Hi,
I have one user who has a problem when switching to the Calender in Outlook. After switching to the Calendar, memory usage for Outlook climbs until it reaches the maximum and becomes unresponsive. The process then has to be killed in the task manager.
This happens on all PCs using that account.
It happens even in safe mode.
It happens even with a brand new Outlook profile.
Running DebugDiag and trying to capture what was going on it seemed that MSO.dll was making millions of allocations, possibly for event handles.
Function MSO!Ordinal1712+81 3,752,079 allocation(s)
Function MSO!Ordinal1712+81
Source Line
Allocation type Heap allocation(s)

That's from early on in the leaking behaviour when it is easier to get the dump finish properly.
Any ideas?
