Unable to save message in shared mailbox
Hello,
I have a curious problem. We are running a Debian bookworm server with dovecot 2.3.19.1. We have a lot of shared mailboxes and most of them are behaving just fine.
But we have a problem with one shared mailbox: Users aren't able to save messages in it even though they have the right to. This issue popped up, when a user This mailbox is set up like every other shared-mailbox, so I don't think it's a permission problem. We tried it with several users giving them the same access rights and always got an error when trying to save a mail in the shared mailbox.
I didn't find anything that could help in the log files. Even after
turning on mail_debug I can't even see the try to save a message in
the logs.
Some of the things I've tried so far without any success:
- doveadm force-resync
- increasing the quota for the shared-mailbox
- disabling the quote for the shared-mailbox
- recreating the Sent folder in the shared-maiblox.
Does anybody have any idea how I can debug this further or where the issue could be?
Mit freundlichen Grüßen

I found this very very old mailing list post: https://dovecot.dovecot.narkive.com/xBrr4hMG/save-failed-to-inbox#post39 It seems to be kind of similar to my problem but it's 18 years old and about dovecot 1.x.
On a whim I tried temporarily disabling the quota (and imap_quota) plugin. And I was able to save messages! So it looks like it's related to the quote plugin, just like it in the 18 year old mail thread.
But I still have no clue how to properly debug or fix this.
Any help or ideas would be appreciated!
Sincerly,

Oh and I think I didn't mention it: copying and deleting works. It's just saving mail that's affected.
