fix: add In-Reply-To and References headers for Outlook reply threading#1246
fix: add In-Reply-To and References headers for Outlook reply threading#1246
Conversation
Microsoft Graph API ignores the conversationId field when sending emails. Instead, it uses In-Reply-To and References headers to determine thread membership. This was causing replies to be assigned different threadIds, breaking draft cleanup, ThreadTracker resolution, and other reply tracking. Also fixes outbound-tracking test to check the original tracker by ID instead of using findFirst which could return a newly created tracker.

📝 WalkthroughWalkthroughCapture the pre-reply ThreadTracker ID and assert that that exact tracker is resolved after reply. Add a threading header builder and propagate RFC‑5322 In-Reply‑To/References into Gmail and Outlook reply flows; Outlook reply path now uses createReply → update → send. Changes

61-83: Consider guarding conversationId assignment.Line 62 may set
conversationIdtoundefinedifbody.replyToEmail.threadIdis undefined, since the condition on line 61 only checks for the existence ofbody.replyToEmail. WhileconversationIdis optional in the interface, explicitly setting it toundefinedmight not be necessary.The header-based threading logic (lines 64-82) correctly implements RFC 5322 standards:
- In-Reply-To contains the immediate parent's Message-ID
- References combines existing references with the headerMessageId
♻️ Optional: Guard conversationId assignment
if (body.replyToEmail) { - message.conversationId = body.replyToEmail.threadId; + if (body.replyToEmail.threadId) { + message.conversationId = body.replyToEmail.threadId; + } // Set In-Reply-To and References headers for proper threading

229-246: LGTM! Improved tracker verification logic.The addition of the
resolved: falsefilter and capturing the specific tracker ID before sending the reply correctly addresses the issue described in the PR. By storingoriginalTrackerId, the test can later verify that this specific tracker gets resolved, avoiding false positives from newly createdAWAITING_REPLYtrackers.
269-283: LGTM! Correct verification of the original tracker.The switch from
findFirsttofindUniquewith the specificoriginalTrackerIdis the correct approach. This ensures the test verifies that the original tracker is resolved, even if a newAWAITING_REPLYtracker is created after the reply is sent. The explanatory comment on lines 270-271 clearly documents why this approach is necessary.apps/web/utils/outlook/mail.ts (2)
30-30: LGTM! Correct type definition for internet message headers.The optional
internetMessageHeadersfield is correctly typed to match the Microsoft Graph API's Message interface structure.
96-96: LGTM! Comment accurately reflects the threading mechanism.The updated comment correctly documents that thread continuity is maintained through In-Reply-To/References headers rather than just conversationId.

✅ Addressed in 19c22fd
There was a problem hiding this comment.
The code has been reverted - we're now using the original if (body.replyToEmail?.threadId) guard, so this concern no longer applies.
There was a problem hiding this comment.
Commit 19c22fd addressed this comment by completely removing the problematic code block (lines 62-77 in the old code). The entire manual threading logic, including the concerning if (body.replyToEmail) condition and the message.conversationId = body.replyToEmail.threadId; assignment, has been deleted. The code now uses Microsoft Graph's native createReply API for proper threading instead of manually setting conversationId and headers.

incorrectly using the OR operator so headerMessageId is not appended when
references exists; change the logic so References is set to either "<references>

options.headerMessageId when not, ensuring a space-separated concatenation per

internetMessageHeadersfield addition correctly matches the Microsoft Graph API's message type and supports the PR's objective of enabling header-based threading.
61-72: LGTM!The implementation correctly sets both
conversationIdand threading headers when replying to an email. The conditional check ensures headers are only added whenheaderMessageIdis available.
85-85: LGTM!The updated comment correctly explains the threading mechanism and provides valuable context about Microsoft Graph's behavior.

Could this helper simply return early when there is no headerMessageId and emit a literal array instead of pushing into headers? Something like:
if (!options.headerMessageId) {
return [];
}
return [
{ name: "In-Reply-To", value: options.headerMessageId },
{ name: "References", value: options.references ?? options.headerMessageId },
];
This keeps the helper short and swaps the || fallback for ??, so an intentional empty references value isn't overwritten.
Prompt for AI Agents:
In apps/web/utils/outlook/mail.ts around lines 356-374, the buildReplyHeaders function
builds headers by pushing into an array and uses || for the references fallback.
Refactor by returning early when options.headerMessageId is falsy (return []), and when
present return a literal array: [{ name: 'In-Reply-To', value: options.headerMessageId
}, { name: 'References', value: options.references ?? options.headerMessageId }].
Replace the || fallback with ?? so an explicit empty references value is preserved.

Commit c0b0aa4 addressed this comment by removing the buildReplyHeaders function entirely and replacing it with a shared utility buildThreadingHeaders imported from @/utils/email/threading. This approach addresses the conciseness concern by moving the logic to a reusable module, and the problematic code with the || fallback no longer exists in this file.
There was a problem hiding this comment.
Done. Refactored to a shared buildThreadingHeaders() helper in utils/email/threading.ts that's now used by both Gmail and Outlook. The helper is much simpler and returns early when no headerMessageId is provided.
- Create buildThreadingHeaders() in utils/email/threading.ts - Fix RFC 5322 compliance: References now appends headerMessageId to existing refs - Update Outlook to use shared helper instead of local buildReplyHeaders - Update Gmail to use shared helper instead of inline logic - Add unit tests for threading header construction

94-102: Avoid emitting emptyIn-Reply-To/Referencesheaders on non-replies.
Right nowbuildThreadingHeaders({ headerMessageId: replyToEmail?.headerMessageId || "" })returns empty strings when there’s no reply target, and those may end up serialized as blank headers. Prefer only setting these fields whenheaderMessageIdis present.Proposed fix

🤖 Fix all issues with AI agents
In @apps/web/utils/outlook/mail.ts:
- Around line 62-77: The current code in mail.ts sets message.conversationId and
populates message.internetMessageHeaders with standard RFC-5322 headers via
buildThreadingHeaders (using body.replyToEmail.headerMessageId and references),
but Graph /me/sendMail will ignore conversationId and reject/ignore standard
headers like "In-Reply-To"/"References"; instead, remove setting
message.conversationId and stop injecting those standard headers into
message.internetMessageHeaders, and switch to using the Graph reply/createReply
APIs (e.g., call the message reply endpoint for the existing thread/message id
from body.replyToEmail.threadId or headerMessageId) or send raw MIME via the
sendMail MIME option to preserve threading; update the logic in the block that
checks body.replyToEmail and the code paths that call sendMail to use the
reply/createReply or raw MIME flow rather than setting internetMessageHeaders.
🧹 Nitpick comments (3)
apps/web/utils/email/threading.test.ts (1)
10-15: Avoidundefined as unknown as stringin the test; prefer typing the API to match usage.
Consider changingbuildThreadingHeadersto acceptheaderMessageId?: string | null(and treat missing as “no headers”), then this test can passundefinedwithout casting (or just remove this test since the empty-string case already covers “no headers”).apps/web/utils/email/threading.ts (1)
6-19: Prefer returning “no fields” over empty strings to prevent blank header emission.
Given usage via object spread, it’d be safer if “noheaderMessageId” returned{}(and the return type used optional fields), rather than{ inReplyTo: "", references: "" }. This also lets call sites passreplyToEmail?.headerMessageIdwithout|| "".Possible refactor
-export function buildThreadingHeaders(options: { - headerMessageId: string; - references?: string; -}): { inReplyTo: string; references: string } { - if (!options.headerMessageId) { - return { inReplyTo: "", references: "" }; - } +export function buildThreadingHeaders(options: { + headerMessageId?: string | null; + references?: string; +}): { inReplyTo?: string; references?: string } { + if (!options.headerMessageId) return {}; return { inReplyTo: options.headerMessageId, references: options.references ? `${options.references} ${options.headerMessageId}`.trim() : options.headerMessageId, }; }apps/web/utils/outlook/mail.ts (1)
118-147: Optional: avoid the IIFE; compute headers once and assign directly.

Learning: In apps/web/app/api/user/setup-progress/route.ts, Reply Zero enabled status should be determined solely by checking if the TO_REPLY rule is enabled, as it is the critical/canonical rule that Reply Zero is based on. The other conversation status types (FYI, AWAITING_REPLY, ACTIONED) should not be checked for determining Reply Zero setup progress.

The new code in sendEmailWithHtml attaches In-Reply-To/References via internetMessageHeaders when replying, but Microsoft Graph only lets you set custom (typically X-) headers through that field; standard RFC headers such as In-Reply-To/References are ignored/stripped by the service when you POST /me/sendMail (see graph/outlook-send-mime-message docs). As a result the intended threading fix never reaches Outlook, and the change has no effect.
Prompt for AI Agents:
In apps/web/utils/outlook/mail.ts around lines 62-75, the sendEmailWithHtml function
sets In-Reply-To/References by writing them into message.internetMessageHeaders, but
Microsoft Graph strips standard RFC headers on POST /me/sendMail so those headers never
reach Outlook. Remove the code that assigns In-Reply-To/References to
internetMessageHeaders, replace it with a short comment explaining that Graph strips
standard headers and that conversationId is the only reliable field here, and add a TODO
(or a logged warning) directing implementers to use an alternative delivery method (send
raw MIME via the Graph endpoint or SMTP) if true In-Reply-To/References header
preservation is required. Keep the conversationId assignment intact. Ensure the change
is limited to lines 62-75 and update tests/comments accordingly.

Commit 19c22fd addressed this comment by completely removing the problematic internetMessageHeaders code (lines 62-77) that attempted to set In-Reply-To/References headers. Instead of just documenting the limitation as suggested, the code was refactored to use Microsoft Graph's createReply endpoint, which properly handles email threading without requiring manual header manipulation. Comments were added explaining that "Microsoft Graph's sendMail doesn't support In-Reply-To/References headers" and that "Only createReply/createReplyAll endpoints ensure proper threading."
Microsoft Graph's sendMail endpoint doesn't support In-Reply-To/References headers via internetMessageHeaders. Refactored to use createReply + send pattern which properly handles threading. - Refactor replyToEmail to use createReply + update + send - Refactor sendEmailWithHtml to use createReply when messageId provided - Add messageId field to SendEmailBody.replyToEmail type - Remove unused threading header code from Outlook

apps/web/utils/outlook/mail.ts (2)
102-124: Consider explicit subject handling for consistency.The refactored
replyToEmailrelies on the createReply endpoint's default subject handling (typically "Re: " prefix) rather than explicitly setting the subject. While this works for standard replies, it may limit flexibility if custom subjects are needed in the future.Optional: Add explicit subject handling
// Update the draft with our content await withOutlookRetry( () => client .getClient() .api(`/me/messages/${replyDraft.id}`) .patch({ + subject: message.headers.subject?.startsWith("Re:") + ? message.headers.subject + : `Re: ${message.headers.subject}`, body: { contentType: "html", content: html, }, }), logger, );
341-391: Avoid non-null assertions per coding guidelines.Line 346 uses non-null assertions (

Address the interface contract violation for Outlook's empty messageId/threadId returns.
The Outlook sendEmailWithHtml function returns empty string for messageId and threadId because Microsoft Graph's sendMail endpoint returns 202 with no body. This violates the interface contract that specifies both as non-empty strings. While the returned values aren't currently used for persistence, this inconsistency with Gmail's implementation could cause silent failures in future code that depends on these IDs.
Consider either:
- Making
messageIdandthreadIdoptional in the return type to reflect Outlook's limitations - Or exploring alternative approaches (e.g., polling the sent items folder to retrieve the sent message ID after send completes)

Addressed - returning empty id (Graph limitation) while preserving conversationId/threadId. The interface allows empty strings which is acceptable for Outlook.

Commit b141df2 addressed this comment by improving the handling of Outlook's empty ID limitation. The code now attempts to preserve conversationId by using body.replyToEmail?.threadId instead of returning undefined, and fixes bugs where invalid draft IDs were being returned after send operations. While the interface contract still allows empty strings (rather than making fields optional as suggested), the implementation is now more correct and better documented with explanatory comments about Graph API limitations.
