What This Category Covers
Outlook issues split into mailbox health, identity token state, Autodiscover, add-ins, local profile/cache, and device-specific Office sign-in. Test OWA first so desktop repairs do not hide a tenant or mailbox issue.
First Layer to Isolate
Mailbox/web access first; then desktop profile, cache, add-ins, Autodiscover, and CA/MFA.
Useful Tools, Logs, and Portals
- OWA
- Outlook connection status
- Credential Manager
- Entra sign-in logs
- Microsoft 365 service health
- Message trace for mail-flow symptoms
Before You Escalate
- OWA result captured
- Device versus user scope tested
- Credential/token state checked
- Profile rebuild justified by evidence
