Configure Email-to-Case (Metadata API)

Configure Salesforce Email-to-Case entirely through the Metadata API (no Setup UI), for headless org configuration. The skill builds a

CaseSettings

source file for the desired

emailToCase

state, then applies it with

scripts/apply-casesettings.py

, which runs

updateMetadata

in two phases — the full

emailToCase

block + Support Settings (Phase A), then routing addresses (Phase B) — and verifies by re-reading. Two phases because a single deploy fails on a fresh org: On-Demand must be live before an address binds (see Rules / Constraints).

Scope

In scope: Enabling Email-to-Case org-wide and setting its toggles (full field lists in Required Inputs and step 4); creating
```
EmailToCase
```
,
```
Outlook
```
, and
```
GmailOAuth
```
routing addresses; applying the change to an sf-CLI-authenticated org via
```
apply-casesettings.py
```
; verifying by re-reading.
Out of scope:
- E2cEasy
  routing addresses — created only through the Service Easy Setup wizard, not the Metadata API; route the user there.
- Authenticating the org — the user authenticates out-of-band (e.g.
```
sf org login web
```
  ); the script reuses that session and never handles passwords or tokens.
- Case object schema, layouts, assignment rules, or Web-to-Case.

Attaching an Agentforce service agent (delegation)

When the user wants an Agentforce Service Agent to answer these emails, configure the Email-to-Case base (the Workflow below), then delegate — this skill never creates or modifies agents.

Gate on org capability first. Attaching an agent needs the org entitled for Agentforce Email-to-Case; that entitlement surfaces as the

BotEmailDefinition

metadata type, so probe read-only before delegating:

bash

scripts/check-agent-email-capability.sh <target-org-alias>   # pins describe to the org's API version

Exit 3 → not entitled: stop, tell the user, and configure the plain Email-to-Case base only — make no Agentforce agent or channel-wiring changes. Any other non-zero is an unreachable org, not "not entitled" — fix auth and re-run. On exit 0, delegate:

Agent creation →
agentforce-generate
, omitting the Service Customer Verification topic (unsupported on the email channel) and including an Escalation subagent so the agent can hand off to a human — on email, escalation transfers the case to a service rep, and without the subagent the agent can't escalate.
Wiring →
service-agentforce-channel-configure
Branch C.

Required Inputs

Gather or infer before applying. Ask only when a wrong assumption would produce a broken or incorrect result:

Target org alias — the sf CLI alias/username of an already-authenticated org. The script obtains the session with
```
sf org display
```
and
```
sf org auth show-access-token
```
; it does not log in for you.
Routing address(es) — for each:
```
routingName
```
(unique label),
```
addressType
```
(
```
EmailToCase
```
default, or
```
Outlook
```
/
```
GmailOAuth
```
),
```
caseOrigin
```
, and
```
casePriority
```
. The platform rejects the address if
```
caseOrigin
```
or
```
casePriority
```
is missing, so treat all four as required in the source file.
Customer-facing email address per routing address — ask explicitly for each, in address order; never guess, default, or reuse from earlier context. Not stored in the source file — passed at apply time via
```
--routing-email
```
(one per address; the script fails closed on a count mismatch).
Support Settings — Default Case Owner & Automated Case User — preserve-first, never assumed:
- Independent, preserved per field. Each configured field is left untouched; change one only if the user asks (
```
--overwrite-support-settings
```
  ). Ask only for the field(s) unset.
- For each unset field, ask (never default to the authenticated user): Default Case Owner type (
```
User
```
  /
```
Queue
```
  ) + value (active Username or Queue DeveloperName) →
```
--owner-type
```
  /
```
--owner-value
```
  ; Automated Case User type (
```
User
```
  /
```
System
```
  ) —
```
User
```
  needs a username,
```
System
```
  needs no value →
```
--automated-type
```
  /
```
--automated-value
```
  (+ optional
```
--system-user-email
```
  for System when the org's automated user doesn't exist yet).
- If any value is invalid, the script fails — get a valid value and re-run; never substitute or guess.
- Pass
```
--use-authenticated-user
```
  only if the user explicitly asks.
Case defaults per address (optional) —
```
createTask
```
,
```
saveEmailHeaders
```
, and an optional per-address Default Case Owner (
```
caseOwner
```
+
```
caseOwnerType
```
), opt-in per address (see step 6): omitted by default so cases fall to the org Default Case Owner / assignment rules. When set,
```
caseOwner
```
(active Username or Queue DeveloperName) must be paired with
```
caseOwnerType
```
(
```
User
```
/
```
Queue
```
); the script validates it against the org, failing closed if absent.
Org-level toggles (optional) — set only if the user asks. Two containers: the emailToCase
section (
```
enableHtmlEmail
```
,
```
notifyOwnerOnNewCaseEmail
```
,
```
enableE2CDeduplicateAttachments
```
,
```
showWordCountInComposer
```
, plus
```
enableE2CSourceTracking
```
,
```
overEmailLimitAction
```
,
```
unauthorizedSenderAction
```
), and top-level Support Settings (
```
enableDraftEmails
```
— plural element name, a sibling of
```
emailToCase
```
). See step 4's table for container/UI-label mapping; top-level scalar toggles apply in Phase A.

Defaults:

enableEmailToCase

and

enableOnDemandEmailToCase

default to

true

(both required — On-Demand before routing addresses);

addressType

defaults to

EmailToCase

. Support Settings have no default — preserved if set, otherwise elicited (never the authenticated user).

Workflow

All steps are sequential.

Confirm the org (and its type) — confirm the target org alias is authenticated (
```
sf org display --target-org <alias>
```
). The apply script checks the
```
Organization
```
row and refuses to mutate a production org (non-sandbox, non-trial) unless
```
--confirm-production
```
is passed — enabling Email-to-Case is permanent and org-wide. If production, tell the user and confirm before re-running with
```
--confirm-production
```
. Sandboxes, scratch orgs, and trials deploy without the flag.
Elicit the routing email(s) — ask the user for the exact customer-facing email address for each routing address (never assume, default, or carry a value over from earlier). Pass them to the script via
```
--routing-email
```
in the order the addresses appear in the source file.
Load the template — read
```
assets/CaseSettings.settings-meta.xml
```
for structure and field placement. Its comments are authoring guidance for you — never copy them into the output. Emit only the elements you set; the output must be comment-free, matching
```
examples/CaseSettings-two-addresses.settings-meta.xml
```
.

Enable the E2C switches, then confirm the optional toggles — set both

enableEmailToCase

and

enableOnDemandEmailToCase

true

(both required; On-Demand must be on before routing addresses can be created — the script enables it in Phase A before Phase B). Then handle the non-required convenience settings, which the template turns on by default:

UI label	Field	Container
Enable HTML email	`enableHtmlEmail`	`emailToCase`
Eliminate duplicate email attachments	`enableE2CDeduplicateAttachments`	`emailToCase`
Show word count in composer	`showWordCountInComposer`	`emailToCase`
Notify case owners on new emails	`notifyOwnerOnNewCaseEmail`	`emailToCase`
Enable Email Drafts	`enableDraftEmails` (top-level `CaseSettings` )	Support Settings

Before enabling these, tell the user exactly which will be turned on and let them opt out (e.g. "I'll also enable these optional settings: … — let me know if you'd like to skip any."). Remove any the user opts out of; keep the rest in their correct container (four inside

<emailToCase>

enableDraftEmails

at the root). Never silently enable these or any other optional flag the user didn't agree to. Confirmed toggles apply in Phase A.

Pick the correct surface per routing address — for each address, decide by
```
addressType
```
using
```
references/routing_address_reference.md
```
. If any requested address is
```
E2cEasy
```
, stop and route the user to the Service Easy Setup wizard instead of emitting Metadata for it.
Populate routing-address fields — for each
```
EmailToCase
```
/
```
Outlook
```
/
```
GmailOAuth
```
address, set
```
addressType
```
,
```
routingName
```
,
```
caseOrigin
```
, and
```
casePriority
```
(all required — the platform rejects the operation with "Missing caseOrigin"/"Missing casePriority" if either is absent), plus any optional case defaults. Do not put
```
emailAddress
```
in the source file — it is supplied at apply time via
```
--routing-email
```
. Do not set the read-only fields
```
emailServicesAddress
```
or
```
isVerified
```
— the platform manages them. See
```
examples/CaseSettings-two-addresses.settings-meta.xml
```
for a complete multi-address example.
Per-address Default Case Owner (opt-in). Ask one address at a time whether cases from this address go to a specific owner or fall to the org Default Case Owner / assignment rules (the default) — different addresses can route to different owners. If the user declines, leave
```
caseOwner
```
/
```
caseOwnerType
```
out of the source file entirely (the template ships them commented out). If the user opts in, ask for the type (
```
User
```
/
```
Queue
```
) and value (active Username or Queue DeveloperName) and set both
```
<caseOwnerType>
```
and
```
<caseOwner>
```
— the platform rejects
```
caseOwner
```
without its type.
```
apply-casesettings.py
```
validates it against the org and fails closed if absent. Do not guess or reuse the top-level Default Case Owner.
Determine Support Settings (Default Case Owner + Automated Case User) — run
```
python3 scripts/apply-casesettings.py --target-org <alias> --input <source-file> --verify-only
```
and inspect
```
defaultCaseOwner
```
/
```
defaultCaseUser
```
/
```
useSystemUserAsDefaultCaseUser
```
. When the user names a value, write it into the source file (
```
defaultCaseOwner
```
+
```
defaultCaseOwnerType
```
;
```
defaultCaseUser
```
, or
```
useSystemUserAsDefaultCaseUser
```
+ optional
```
systemUserEmail
```
) — the scored, versionable artifact; the script also accepts these as flags. Leave each field the org already has as-is — omit it and it is preserved (override only if the user asks — then
```
--overwrite-support-settings
```
). For a field unset and unnamed, ask; never assume the authenticated user (
```
--use-authenticated-user
```
only if explicitly asked).
Validate the source file — run
```
python3 scripts/validate-casesettings.py <path-to-source-file>
```
and resolve any reported errors before applying.
Apply to the org — run:
bash
```
python3 scripts/apply-casesettings.py --target-org <alias> --input <source-file> \
    --routing-email <email-for-address-1> [--routing-email <email-for-address-2> ...] \
    [--owner-type User|Queue --owner-value <username-or-queue-devname>] \
    [--automated-type User --automated-value <username> | --automated-type System [--system-user-email <email>]] \
    [--confirm-production]
```
Provide exactly one
```
--routing-email
```
per routing address, in document order. Supply the owner/automated flags only when the org's Support Settings are not already configured (step 7); if configured, omit them and they are preserved. If the script rejects a value as invalid, relay it, get a valid value, and re-run — never fall back to the authenticated user. If the script reports production and exits, do not add
--confirm-production
yourself — confirm with the user first (step 1). The script applies Phase A (support settings + toggles), then Phase B (routing addresses), re-reads to verify, and exits non-zero on any fault.

Confirm the result — check the JSON summary:

verified.enableEmailToCase

verified.enableOnDemandEmailToCase

are

true

verified.routingAddressCount

matches the address count, each

phaseB

entry is

status: created

(or

already_exists

), and

supportSettings.action

preserved-existing

set-from-input

set-from-authenticated-user

. Use

--verify-only

to re-read without writing.

Configuration is complete after step 10.

After setup — post-completion guidance

The items below are not workflow steps — present them to the user once setup is confirmed.

Forwarding (required for real inbound mail)

Always give the user this guidance — it is how inbound mail to the customer-facing address actually reaches Salesforce:

Your routing address now has a Salesforce-generated email services address. To receive inbound mail, configure your email system to forward mail sent to your customer-facing address (e.g.
support@company.com
) to that generated services address.

End-to-end proof (Act 3)

Offer to prove inbound email creates Cases — a live round-trip; skip it if the user declines. The skill never sends email — it orchestrates two human actions, then verifies with SOQL: (1) Address ownership — Salesforce emails a confirmation link;

isVerified

flips only when the human clicks it. Tell the user to click it and wait. (2) Send a test email — ask the user to send one real email from an external mailbox to the routing address's Salesforce-generated email services address (not the customer-facing address, which only receives mail once forwarding is configured), report the sender, and wait. (3) Verify with evidence — then run:

bash

python3 scripts/apply-casesettings.py --target-org <alias> --verify-cases \
    [--supplied-email <external-sender-address>]

Read-only: it queries

Case

where

Origin='Email'

(last 3 days, optionally narrowed by sender) plus the linked incoming

EmailMessage

rows (

Incoming=true

ParentId

= the new Case), and exits non-zero if no matching Case has a linked incoming email (mail not processed yet — wait and re-run — or address not verified). On success it prints the

Case

EmailMessage

evidence with

proven: true

Rules / Constraints

Constraint	Rationale
Apply via `apply-casesettings.py` (two-phase `updateMetadata` ), never a plain deploy or a minimal `emailToCase` patch	A single deploy fails on a fresh org; the full `emailToCase` block (not a field-level flip) is what provisions On-Demand before addresses bind. See `references/apply-mechanics.md` .
Write only the top-level fields the skill owns; never echo the whole `CaseSettings` record	The platform re-validates every top-level field in the payload (e.g. Case Feed → Chatter); sending only `emailToCase` + `enableDraftEmails` + Support Settings avoids unrelated failures and needs no Chatter prerequisite. Omitted fields keep their values via field-level merge.
The customer-facing email must be explicit user input ( `--routing-email` ), never in the source file and never assumed	Prevents a guessed or stale address from being provisioned. The script fails closed if `--routing-email` count ≠ address count.
`CaseSettings` `fullName` is always `Case`	It is an org singleton settings type; the script targets `Case` automatically.
Support Settings are preserved per field if configured; never assumed if not	Default Case Owner and Automated Case User are independent — each configured field is left untouched (unless `--overwrite-support-settings` ), and only an unset field requires an explicit, org-validated value (fails closed otherwise). The authenticated user is used only with `--use-authenticated-user` .
Automated Case User "System" and a named `defaultCaseUser` are mutually exclusive	`--automated-type System` sets `useSystemUserAsDefaultCaseUser` and must not carry a user value; the platform rejects both.
The script reads → patches → updates (append-only for addresses)	It merges onto current settings, so existing routing addresses are preserved; a duplicate `routingName` / `emailAddress` is reported as `already_exists` . New addresses are emitted before existing ones ( `updateMetadata` replaces the collection wholesale and would drop an existing address that a new one follows; a runtime guard fails the run if any existing address is dropped). See `references/apply-mechanics.md` .
`EmailToCaseSettings` is never applied directly; `enableEmailToCase` cannot be turned off once on	It is written only as the `emailToCase` child of `CaseSettings` . The platform permanently enables the feature after the first `true` apply; never rely on setting it back to `false` .
Production orgs require explicit `--confirm-production` ; never add the flag unprompted	Enabling Email-to-Case is permanent and org-wide. The script fails closed on a non-sandbox, non-trial org (and one whose type it can't read) until the user confirms. Sandboxes and trials are exempt.
Proving inbound Cases is a read-only step the user triggers; the skill never sends email	`--verify-cases` only queries `Case` / `EmailMessage` after the human verified the address and sent a test email. Fails closed until a Case with a linked incoming email exists.
`E2cEasy` addresses must use the Service Easy Setup wizard	The prebuilt `service_case` queue binding and `isVerified` flip are not reproducible through the Metadata API.
Never write `emailServicesAddress` or `isVerified`	Both are read-only, platform-generated; the script strips them if present.
The generated source file contains only the elements being set — no XML comments	Template/example comments are authoring guidance, not output. Copying them bloats the file (gold is comment-free) and CLI-example comments with `<placeholder>` tokens can fail XML validation. Put explanation in your chat reply, never in the `.settings-meta.xml` .
