I have an AD/Exchange 2010 setup that usually works pretty well. However, after installing Outlook 2010 on the server and choosing to "remember the password" for a user who is not an administrator, whenever I start Exchange Management Console or Exchange PowerShell many functions are not available to me (cannot "edit") and it seems like I am connecting as the user.
Same advice as HopelessN00b:
- Do not install an e-mail client on your mail server
- Do not let non-admins access your mail server
- Do not cache credentials on your server.
To remove the "cached credentials", go to:
Control Panel -> User Accounts -> Credential Manager
You should be able to delete them here.
