I migrated from a Courier-IMAP setup via imapsync. Everything worked great but my users have a minor issue in that the "Drafts" folder has like 20 unread messages in the folder list. And first off there aren't ANY messages in the folder and the option to "mark this folder as read" is grayed out. To clear it out I've tried:
1 - composing a new message
2 - saving it as draft (the unread count now becomes 21)
3 - going to the Drafts folder and marking the message as "unread"
4 - when I right-click on the folder I can now select "mark this folder as read" but clicking on it doesn't do anything
5 - I move the message into the trash and it subtracts the count and it becomes 20 unread messages again... *sigh*
Like I said, not a MAJOR show-stopper issue but a minor annoyance. I don't know enough about Zimbra's underlying structure to figure out how to solve this one. Is the unread count stored somewhere like in the SQL database that I can reset it by hand?
