Steps to reproduce
Win 11 26H2 - after auto update to 159 10/31/2026 when opening TB previous mail was not shown for one account, folder tree was not in sync (noting the condition occurred often but was "intermittent").
Actual results
Folder inbox would sometimes show but not sync. Closing and re-opening TB would change behavior, occasionally working normal (proper sunc) after successful using the subscribe function and if it was successful TB worked normal until closed and reopened. Checked folders on IMAP server, everything was present and working normal. Removed and recreated the affected account, no change. removed and reinstalled TB (same profile) no change. Created test profile with affected account, no change.
Down graded to version 158 everything is restored to normal operation, even with original profile. This occurred on one lap-top and one desktop both 26H2 and both resolved after 158 was reinstalled.
Expected results
Previous mail should be shown and new mail sync when opening TB
Note: no changes in settings were made prior to issue only the update to 159
I see after posting (sorry) this is the behavior reported more thoroughly in Bug 2087454
I assume proper procedure is to mark this as duplicate to 2087454 - Thank you
