We have two remote users (in Mexico) who have configured their Blackberries to allow access to their work emails. As of two weeks ago, this process was working. For reasons unknown, this has suddenly stopped working but they are still able to access their emails under other addresses. No changes have been made to our Exchange server settings. When attempting to set up the email on their Blackberries, they receive a message saying that their password is incorrect. Again, no password changes have been made. However, we did attempt to change one of the user's password but to no avail.
Any ideas or assistance would be very much appreciated.
