Our users have been complaining about an issue were Outlook will hang for 7 minutes with an hour glass when try to access the Delegate Access window to add or remove delegates from their mailbox. After 7 minutes the Delegate Access box will come up and the user does not have other issues editing the delegate list.
I am able to reproduce this issue on my workstation. Using procmon I found that over a 7 minute window the application searchindexer.exe started many processes of itself with durations longer then one second. (below is a screen shot my procmon capture.) Also during this time the Outlook application would show a bubble stating that it is trying to access the CAS Array. My company is running Exchange 2010. We do not allow any RPC access to any of the Exchange servers including the mailbox servers. All Outlook traffic has to be Outlook Anywhere traffic over https.
I know the searchindexer.exe process is the Windows Search service but I am not sure why it is being access during a delegate change. I am looking for any help in regards to this issue.
