whykillme -> Multiple Users receiving Multiple Mails (14.Oct.2011 3:59:19 AM)

Hello,

Recently several users have been receiving multiple mails at random times that are exactly the same.

New mails they receive now are only received once, but some random mails sent a few days ago are constantly being resent to a user.

For example:

User A received mail X on Day 1 - 3 times, at random times on the day.
User B received mail Y on Day 1 - 3 times, at random times on the day.
User C reveived mail J on Day 1 - 3 times, at random times on the day.

User A received mail X on day 2 - 2-6 times, at random times on the day.
User B received mail Y on day 2 - 2-6 times, at random times on the day.
User C received mail J on day 2 - 2-6 times, at random times on the day.

Newly sent/received mails don't give this problem, but for whatever reason those several mails keep being resent. Could this be a problem that the senders "sent items" box is full or queueing, so sending mails several times? But why are they being sent for several days now?

Mail headers gives nothing of use either, they're all the same except for the time of sending/receiving.

But why did this happen to only a few users, with a few mails, and nothing is happening anymore for new mails coming through, just those that keep coming back?

The mails aren't big of size either, not even 1 MB each. And since this happend several 10MB mails went through just fine.

Using Outlook 2010 and Exchange 2007.

If anyone has had this problem before, please help me out.

Greetings,


WKM
