MS Outlook 2024 LTSC automatically gets closed and later not getting open
In Outlook 2024 LTSC, the application suddenly stops and closed automatically. Later troubleshooting, it is observed that it doesn't even open in safe mode. Tried to create a new profile where it is ...
Based on your description, the issue does not appear to be related to the Office installation itself, since reinstalling Office did not change the behavior.
The more significant symptom is that Outlook is unable to discover the Exchange mailbox and instead redirects to a Microsoft 365 sign-in page when creating a new profile. This may indicate an Autodiscover configuration issue, a hybrid environment misconfiguration, cached credentials, or a problem reaching the Exchange services.
I would recommend checking:
- Autodiscover functionality for the affected user.
- Outlook Connectivity Test (Microsoft Remote Connectivity Analyzer).
- Windows Credential Manager for stale Microsoft 365 or Exchange credentials.
- Exchange virtual directories and Autodiscover SCP configuration.
- Whether the issue affects only one workstation or multiple devices/users.
Since Outlook is also crashing before opening, reviewing the Windows Event Viewer (Application logs) for Outlook crash events and faulting modules may provide additional clues.
