Since December 2022, compacting is not working properly. I have set TB to ask me whether to compact when 100 MB would be saved. This has worked fine for years. Since December, I receive a pop-up advising that 237 MB or slightly more can be saved. After compacting, the message repeats every hour or two.
Compacting is actually, working except for the 237 MB chunk of data that either can't be compacted or doesn't really exist and fools TB into thinking compaction is needed. For example, if I set the compaction threshold to 500 MB then the mailbox will grow and I will eventually receive a reminder to compact when more than 500 MB can be saved. Compacting at that point does indeed shrink the mailbox. But, immediately thereafter, if I set the threshold back to 100 MB I get a message that 237 MB can be saved by compacting. Thus, the compact request repeats endlessly, all day long.

I can't take it any more. Does anyone have a suggestion for forcing TB to re-examine or re-index my inbox in a manner that correctly determines its size and ends this nuisance?
