Read/Unread emails in Thunderbird
I’m facing a problem with the read/unread flag with Thunderbird
Most of the time, when an email is read it becomes unread again after a while.
This happens on most of our accounts, and on Mac and Windows, and doesn’t seem to happen when using another email clients or with same Thunderbird using another email server.
Any idea on where to look or what could be the problem ?
please provide more details such as versions used, logging, etc.
I’m using 8.7.82 on a Debian Buster, logs don’t say anything special.
I found this https://jira.kopano.io/browse/KC-1444
I ran the dbadm, I’ll see after few days if problems still exists.
