Assuming your issues are client side as already suggested, when setting up an account in Thunderbird there is an advanced/semi-hidden option to choose between storing the local copy in either mailfile (default) or maildir (option, with unnecessary warning about experimental nature after several years in the software). I strongly reccommend to select maildir format in which case the cached copies of emails are stored as individual fles in a directory, rather than all appended to a single enormous file which has to be loaded into memory each time you start TB, thus massively cutting the client resource overhead.
Our organisation has had at most 20 mailboxes active at any one time, yet my director always had trouble under outlook because he doesn't manage his inbox and outlook stores the cached inbox in a single file with a fixed size limit (which he was exceeding). I made the decision about 8 years ago to move to TB configured to use maildir, and barring periods where my director reinstalls his laptop and forgets to enable maildir on recreating his mailbox, his system he not been brought to a standstill by email since.
About the warning about experimental support - we are using it with imap, even if the local copy has an issue, the server copy is still there, besides which, it appears to have been stable for many years.

Thank you Jim,
I forgot to mention, we do not pull full emails from server, so, there is no local copy.
It just could produce more problems.
Suddenly, our 1.3TByte emails could be easily 2-3TByte, as our users like to send CC to their colleagues, so, 1 copy on server could cause 4-5 copies on clients.
Fortunately my experience with TB accessing folder with 163000 emails is pretty quick, no problem. (I don't like TB, I think it is a crap, but this is my private opinion, nobody cares).
It seems I only have performance problem with imapsync, when I have to migrate some users' thousands of folders into one big folder and on every source folder triggers a full crawling headers of the big folder, which takes time.
I was just curious, what is others' experience with such a large amount of folders.
Thanks!
István
