Understanding the Issue
DavMail is a gateway that allows users to access Microsoft Exchange services through standard protocols like CalDAV, CardDAV, and IMAP.

This can cause the calendar to endlessly attempt to sync, displaying repeated notifications or freezing Thunderbird altogether.
Original Code Example
In order to better understand the troubleshooting process, here’s a code snippet that might typically be found in the configuration of DavMail:

<url>http://yourserver/davmail/calendars/</url>
<username>yourusername</username>
<password>yourpassword</password>
</caldav>
Analyzing the Update Loop Issue
The update loop may arise due to several factors:
- Configuration Errors: Incorrect DavMail or Thunderbird settings can lead to repeated sync attempts.
- Network Issues: Poor connectivity or server outages might cause Thunderbird to retry the connection endlessly.
- Version Compatibility: Outdated versions of either Thunderbird or DavMail can create compatibility issues.
- Calendar Size: Large calendars with many events might overwhelm the system, causing slowdowns and retries.

-
Check Logs: You can find logs in DavMail that might provide more information about the sync issues. Look for error messages that indicate what might be going wrong.

Restart Services: Sometimes, simply restarting the DavMail service or Thunderbird can resolve temporary issues.

Limit Calendar Size: If you have a particularly large calendar, consider archiving old events to streamline the sync process.
