### Analysis of Worker Logs and Resolving Office 365 Sync Issues

The logs are a goldmine—your worker (`twenty-worker-1`) is actively running Office 365 sync jobs for both email and calendar, which is great news! However, there’s a critical error: **"Application is over its MailboxConcurrency limit"** from Microsoft Graph API, causing the `MessagingMessageListFetchJob` to fail when importing emails (seen at 8:15:44 PM and 8:19:06 PM on Oct 8, 2025, and 3:15:17 AM on Oct 9). This explains why emails might not be appearing in Twenty’s **Emails** tab despite successful connection and calendar sync working fine.

The **MailboxConcurrency limit** is a Microsoft Graph throttling issue, meaning too many simultaneous requests are hitting the API for the account (e.g., `ron@nuvemxp.com` or `scott@nuvemxp.com`). This is common in self-hosted setups with large inboxes (e.g., 823-827 messages per sync) or multiple accounts syncing at once. The calendar jobs (`CalendarEventListFetchJob`) complete successfully (e.g., 2,447-4,530ms), so calendars should be syncing, but email imports are stalling.

Here’s how to fix the concurrency issue, confirm sync, and ensure everything runs smoothly. We’re in `~/twenty_project` with your setup on `https://crm.nuvemxp.com`.

#### Key Log Insights
- **Microsoft Sync Jobs**:
  - `MessagingMessageListFetchJob` (e.g., 4:07:53 PM, 30,679ms): Attempts to fetch 684-827 emails in batches (200+200+200+200+23/27) for `ron@nuvemxp.com` and `scott@nuvemxp.com`. It finds 7 folders but hits the concurrency error.
  - `CalendarEventListFetchJob` (e.g., 4:07:25 PM, 2,447ms): Completes without errors, indicating calendar sync is working.
  - `MessageParticipantMatchParticipantJob` and `CalendarEventParticipantMatchParticipantJob`: Post-sync jobs to link emails/events to CRM contacts (running fine, ~20-256ms).
- **Errors**:
  - `[MicrosoftHandleErrorService] Error: Application is over its MailboxConcurrency limit` (8:15:44 PM, 8:19:06 PM, 3:15:17 AM): Graph API throttling.
  - `Cannot read properties of undefined (reading 'includes')`: Follow-on error from failed token refresh during throttling.
- **Other Jobs**: `CallWebhookJobsJob`, `CallDatabaseEventTriggerJobsJob`, etc., are for webhooks/automations (fast, ~2-96ms, no issues).
- **Cleanup**: `MessagingConnectedAccountDeletionCleanupJob` deleted 326-373 stale messages (normal maintenance).
