Wondering if anyone can point me in the correct direction for dealing with a really annoying issue. The last few weeks we have had mail flowing really well and now the following issue has popped up yet again. I have no idea why after everything has been working well. No changes have been implemented anywhere so I'm stumped as to why this has started happening.
The problem is on some of the queues with the following message:
432 4.3.2 STOREDRV.Storage; mailbox server mapi session limit exceeded; STOREDRV.Deliver.Exception:TooManyObjectsOpenedException.MapiExceptionSessionLimit;Failed
Google has not been my friend when looking at this and what happens is that the relevant queues this hits builds and builds and then it re-tries, deals with a shit load of mail and then it starts to build again.
