Odd issue.
Despite allowing all of my accounts to use activesync from their mobiles(android/iphone), some of my accounts cannot connect.
Using the same devices, I can connect and sync properly using my own credentials.
If I create a new exchange account, I can connect to it just fine using the same devices.
Mobile use seems to be enabled on all of the affected accounts...
What am I missing?
Thanks very much for your time.
