I too am having trouble reinstalling the msextmz.msi ver.2 after uninstalling the previous version.
A separate question, how do I grant Send As permissions to all mailboxes to a user account on Exchange 2k3? Do I have to create a new account named "Admin" for the MS script included in KB930879 to work or can it be any account? Does it have to be an account that is not a member of the domain or Exchange admins, since they are denied these permissions?
I can get through everything up until the running of the batch file at the end and for some reason after running it, I get prompted for credentials for Outlook after moving past the first user account, even though I have it set to automatically open the account I setup. I'm using Office 2007, XP Pro and Exchage 2k3. Any help would be greatly appreciated.
Thanks
