I was suffering the same problem with my 2003 => migration and it was only after very careful and methodical testing that I got it to work.
First, refer to:
BlackBerry Search Results
specifically, this command:
Quote:
get-mailboxserver Exchange2007 | add-adpermission -user <BESAdmin> -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin
|
After applying the command with your site-specific details, run:
Quote:
get-mailboxserver Exchange2007 | get-ADpermission -user BESAdmin | Format-List
|
and you should get a total of six (6) ADpermission settings (I had originally only gotten two which indicates to me that my first run at applying the settings from command line had not applied correctly).
Once that is confirmed, you will then be able to run IEMSTest.exe successfully.
