I see a double standard here...
The fix, supposedly, has been implemented as a necessary security measure. But there has been nothing done, and probably won't be anything done, to prevent admins from being mailbox enabled.
MIKE: As a general best practice, you really shouldn't have someone reading their email or surfing random web sites while logged on as domain admin. What if an administrator's curiosity about that purported new Anna Kournikova pic gets the better of him for a second? I know this is inconvenient. But ignoring this best practice isn't just less than optimal, it's close to reckless.
As a best practice, yes I agree that we all should be dilligent and follow best practices... However, if we are allowed to mailbox enable admin users, you should be obliged to provide information to fix what you have broken.
