    Hello, we tried your solution. At first it seemed like it would work. Unfortunately, the error continues to appear after a few minutes. All computers are now affected. There is no solution at all. Thanks for your help.

    After some testing it must be outlook related. Once I upgraded to latest version the error immediately occured.

    Unfortunately downgrading back to the previous version does not fix the error like already mentioned by C.Gellermann.

    Exact same issue here.

    First noticed January 3rd around 09:00 am. Running on Outlook 2102 (Build 13801.21092 CTR) - Synchronizer Version 16.0.13801

    Readding favorites solves issue for a single sync, same when recreate mail profile.

    Does NOT happen on a fresh installed PC with older Versions :

    Win 10 1909, December patches NOT installed, Outlook Version 2008 (Build 13127.21624 CTR)

    Which AV scanner do you all have ?

    Hi SV&&&,,

    Thanks for the update. May I know which Outlook 365 desktop client version are you using please provide us with the detailed information about this, see About Office: What version of Office am I using?

    Does this issue recently happen such as after update to latest version of Outlook 365 desktop client?

    @C.Gellermann, as you mentioned that "The errors have been occurring since December 31, 2021". If the issue happen after latest update you may use the workaround revert to earlier workable version if it is acceptable for you. Here is the article which has detailed steps listed: How to revert to an earlier version of Office

    Note: If your organization IT team/Office 365 admin manage Office deployment please contact them for revert to earlier version.

    Your patience and understanding will be highly appreciated.

    Best regards,

    Shyamal
