Running 64-bit 102.1.2 on Windows 7 (need to maintain Windows 7 as part of my work). When I first upgraded to 102.1.2, the local (synchronized) copies of my mailbox were immediately corrupted. Server copies are fine. I saw, for example, that many key folders had dozens or even hundreds of sub-folders of the same name with a sequence number tacked on (INBOX-0001, INBOX-0002, ... INBOX-1050 for example -- I forget the exact zero padding but it was in the names). I tried a few things then resorted to removing all the local *.msf files for a full rebuild. This is a fairly large set of folders so rebuilds can take a while but this one seemed a lot slower. Then, during the rebuild it would stop and leave some IMAP folders unsynchronized. In some cases this caused filters to fail with "no such folder" type errors. I thought I finally had it fully rebuilt, which involved having to visit each folder, or select sets of folders and compact them. But then, on exit/restart, a bunch of folders were once again out of sync. I have the total messages header set for folders and I'd see big chunks of those empty after restarting -- where I had just painfully got them all sync'ed and showing totals before the restart. The total folder size still shows, but upon visiting the folder it ends up doing a full sync of that folder. Some of these folders have a lot of message so this has become extremely painful. And if visit enough folders it bogs Thunderbird way down running their resync's in parallel (there seem to be a limit to how many though). It can slow Thunderbird way down, to the point of not being able to use it for periods of time ... sometimes the hourglass is also on for a long time (10-20 minutes). The folders are no longer corrupt -- just some subset of them (which seems to move) are continually in a state of resync.
Any ideas appreciated, including any ways to easily resync all folders in a sane way. I have the account set for all to sync but it seems like I either have to visit the ones out of sync or select them as part of a compact operation. Very time consuming and now I'm headed back to the workweek where I need to be able to use this account.
I've checked the physical disk the local folders reside on and it's not reporting any issues (plus I have other things on that disk that are having no issues).
