problem deleting messages in inbox

I have 3 email accounts in Thunderbird, all POP3 type via Spectrum.

I’ve been having intermittent problems with one of the accounts, namely that I can't delete some messages in the Inbox. (The Inboxes for the other 2 accounts seem to be fine.) When I try to do so I get a "Thunderbird is not responding" message and everything freezes. I have to use Task Manager to exit the program.

I went to Help >Troubleshooting and cleared the cache, disabled add-ons, etc., but no luck so far.

I would really appreciate any suggestions. If the only remedy is to uninstall and re-install TB, how do I do that?

Thanks!

Matt,

After reading a few more posts here, instead of disabling the Windows Defender real time anti-virus function completely, I created an "exclusion" for my Thunderbird profile folder. That continued to fix the problem.

Then, after a few days, as a check, I removed the exclusion. Lo and behold, the problem remained fixed! So, (fingers crossed), I'm back to normal.

Thanks again for your help.

have you tried disabling your anti virus which may well be locking the inbox?

Try compacting from the File menu and see if that helps.

Generally issues as you describe come from 1. Antivirus scanning locking out the file. (simple expedient of restarting in safe mode with Networking will remove that.) 2. The actual storage file having issues with regard to corruption or allocation. Generally you needs to use the system utilities to "de-fragment" the file system as that will identify file system errors. 3. An oauth authentication window open in the background. Hover your mouse over the icon on the task bar and see if there is a second window showing open. Just about everything fails when there is an "enter credentials" windows open including getting mail 4. An addon might be the issue. Restart from the help menu in troubleshooting mode and continue when prompted. Does that change anything?

Matt, thanks very much for your detailed answer and suggestions.

This problem seems to be both persistent and intermittent. The next time it happens I'm going to try your suggestions. A couple of them I'm not sure I know how to do (complete amateur here) so I may be asking for more guidance at that time.

Thanks again, much appreciated!

Matt,

A strange twist. Now things are back to normal with the inbox for the email address which initially had the problem. But the same problem has now somehow "transferred" to the inbox of a different email address! That is, when I try to delete (or move) a message from there I get a "Not Responding" message and then a long delay before it finally deletes (or moves).

Your first suggestion, though, does seem to temporarily fix things---disabling the anti-virus. But for obvious reasons I don't want to have to take that step each time I want to delete (or move) a message.

Do you have any suggestions?

Again, many thanks.

Andrew
