Outlook 365 (classic) freezes syncing subscribed folders via IMAP
Since when are you experiencing this issue? When did it work correctly the last time?
Which add-ins do you have installed?
Disable the non-default ones (especially any security suite which integrates itself with Outlook) and try again.
See; Enable/Disable add-ins - Robert 365
Note that you are using an almost month-old Current Channel (Preview) release. There have been 5 new releases since then. Update to the latest build and see if you can still reproduce the issue. Also try using the non-Preview build and verify whether the issue goes away then.
Things breaking or not working as expected can happen more frequently when using the Preview/Beta releases.
Sorry for the delay in answering you. Trend Micro has just published a major update for their Maximum Security and wanted to see if the issue continues. It does, unfortunately.
I experience the synchronization freezes for several months now. I do not recall the exact time, but it is a good while ago when it started. I will try disable the addins, following your link - thank you. I have no active add-inn showint in OL options. there are several inactive ones: 4Team OL premium support; MS access OL add-in for data collection and publishing; MS Exchange addin; MS VBA for OL addin; and OneNote notes about OL items. the one from 4Team is likely Sync2 that I use for syncing Calendar, Contacts, and Tasks with Google.
I do not use Current Channel, never did. It's likely installed with a Win 11 or MS 365 update. I was not even aware of it untill your reply. Where is it located and do I need it, or can I force stop it, uninstall or get rid of it somehow?
Thank you very much for looking into my very annoing issue.
