High CPU utilization on outlook 2007 when opening dialog

[Oren Gurfinkel]

Hello all,
I've developed an add-in to outlook 2007 using IDTExtensiblity2 , When the
add-in get installed on a machine with service pack 2 after a while each
dialog opening and closing result in high CPU utilization.
When I check the running threads in process explorer I noticed that one
thread consume most of the CPU and this thread start address is in
outlook.exe : LoadPrivateMAPI
Any idea ?
Thanks
Oren.

What language are you using? What development platform? Are you using only 1
thread for all of your Outlook object model calls? Using a background thread
for those is a terrible thing to do.

Are you releasing everything? Are you calling the garbage collector if this
is managed code? Have you checked with a profiler to see where your code is
slowing down?
