Title: RE: Exchange 5.5 SP4 Duplicate Messages

To make a long explanation short, the users are accustomed to downloading their email to their laptops so they can do all their email as they travel and plug in when they get to a hotel. Using .ost files and waiting for syncronization once reconnected hasn't been well received.

Email should always be left on the server for the Exchange Side.. Having them D/L all messages locally is bad juju.

I should have mentioned in the original message that the resources in the Private Information Store - Mailbox resources showed he had completely downloaded all messages and the mailbox was empty. When disconnects with POP3 occur, I always send users to OWA to clean out the offending large file (usually a powerpoint presentation).

In the past, when large files and interrupted pop3 sessions occur, users generally try two or more times and find they have many duplicates of a message. The problem I have here is messages are duplicated once and once only, so it appears to me to be a problem in the IS somehow.

If it was with Internet mail, it could be that his POP3 connection crapped out, and it is leaving the message on the server.  And then when it retries, it downloads it again.  You can have him connect to the server using a POP3 viewer (like Lydia) and viewing the headers without touching them. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Help!

I have one exchange box running nt4 SP6a with exchange 5.5 SP4 on it. We migrated from Ipswitch Imail a year ago and everything to date has gone well with Exchange except for one nagging problem I cannot find a resolution to. Duplicate email messages intermittently will occur in various users Outlook 2000 mail client. I originally thought the problem was only with users who have both exchange and internet mail services configured in Outlook 2000. Those people were told to pick one and stick with it. Recently however, a user configured for IMO in Outlook 2000 began receiving duplicate messages as well. This is a remote user, so he dials up to the internet sporadically through the day and checks for email. The duplicates will appear in the first download of the day, but clear up afterward. It is all messages that are duplicated when this happens, not just messages addressed to DL's or multiple recipients. I can locate technet notes on duplicate messages in public folders, but I cannot find any info on problems with duplicate messages in user mailboxes.

Thanks for any help.
