Comment 10 for bug 160142

I am using Evolution 2.24.5 on Fedora 10. I don't think the distro is important here. I am seeing this same issue. I typically move my email to an archive folder when I think I am done with it, so I rarely have more than 100 emails in my inbox. However, some of them can be a few weeks old.

This is germane because I will have random incidents where some messages will disappear from Evolution. It's not all messages or even all messages before X date. It's not all messages received after some point in time. Sometimes it will be messages a few minutes old. Sometimes messages from a few days ago. But I will generally still retain some messages both newer and older than the disappearing messages. I have noticed that threads tend to disappear as an atomic unit. The disappearances tend to happen after restarting Evolution which I mainly have to do on reboot, but I believe some occurrences happened when simply changing folders.

The messages are not really gone. I can log into Webmail (Is there any other user interface that screams, "We hate users!" quite so vociferously?) and still get to them. Sometimes moving them to another folder and moving them back to the inbox will cause them to reappear in Evolution, sometimes not.

When messages disappear like this, the unread count for the inbox goes haywire. Sometimes it will reflect the new messages I can see in Evolution. Sometimes it will reflect the new count on the server. Sometimes it will reflect a random number in between.

As reported by others, I only see this with Exchange. I never have problems with my local archive folder.

Seeing the advice above about removing folders.db, I tried to see if I could narrow it down. I did this:
- Shutdown Evolution
- Made a backup of folders.db
- sqlite3 folders.db
- delete from 'personal/Inbox';
- Started Evolution

This worked for me. Just clearing that one table forced a server resync for the inbox folder. It definitely seems like a corruption issue. If it helps, the missing messages were no longer in the personal/Inbox table at all. It wasn't a matter of having corrupt data in the table. I had 39 messages in my table before I purged and 111 after I resynced.
