Cannot Open Imap folder with Multiple threads in read/write mode - getting denied. It only allows one thread.
This article is expressing my same issue and refers to Exchange Throttling:

However, I have increased all throttling in a new throttlingpolicy I created just for this user to unlimited. I have set Imap eventlogging to high for both imap and imap BE. I'm still not seeing any indication why Exchange could be blocking another thread to open that same folder in read/write mode.
How can I further debug this or fix this?!
