Hi,
Whenever our users publish their Projects they get this error:
<error id="40512" name="ExchangeSyncGeneralProcessingFailure" uid="5b9af4d1-00d1-4556-95e4-05e496700ad2" teamMemberUid="2bf044d1-357c-4bc7-8133-5152a44488df" exception="System.ArgumentException: An item with the same key has already been added.
This only started to happen last week and the ULS Log doesn't provide any more information. The Job queue shows a number of errors for "Exchange Server Task Sync" with a job state of "Failed but not Blocking Correlation". Does anyone know what could be causing this? The users were able to publish their projects successfully before. We are using Exchange 2010 SP2 rollup 6 and Project Server 2010.
Thanks.
