So I recently moved from CommuniGate Pro to the Open Source version of Zimbra (yeah ). One very strange behavior that I have not quite been able to figure out ....
I used imapsync to move the mail store from CGatePro to ZCS. During the migration weekend, I ran imapsync multiple time while I was waiting for DNS propagation to take effect. During different syncs, I noticed on my BB (using a BIS connection -- no BES), that some older messages would start to show up as new.
My initial thinking was that it was related to the imapsync. However, since the migration finished, and imapsync has not been run in well over a week, I am still getting random reports of this phenomenon from both BB and iPhone users.
I have not been able to find anything in my logs, but a pattern that I have noticed is that whenever it happens to me, or to other people in my department; it seems to happen after opening up an IMAP client (Entourage, or Mail.app) for the first time in several days (we are trying to get everyone to use the web client). I have also had Outlook users report this behavior, but they have never been willing to own up to having opened Outlook (since they are not suppoed to be using it).
Is there any chance that I am on the right track here? Could some sort of re-index, or scan of the mail store cause certain messages to be reported again as "new"? Mind you they never show up as Unread in the ZWC, or in the ZDC, or in the IMAP client (Mail, Entourage); they only show up on the phones.
I have made a good faith effort to warn all of my smartphone users about this, but my concern is that they may not always notice it; and reply to a client about something that is outdated. It won't take too much loss of face before I am having to look at migration plans that don't involve ZCS as the destination.
