Exchange 2013 installed and working - until now. Prompts random users for username/pass
Hi all --
got a very weird issue with an Exchange 2013 install for a client of mine. We have installed and configured Ex2k13 and have had it running in pre-production for a month or so now (incl SSL certs). No issues.
Configured the user bases roaming profiles to use the new exchange accounts after PST migration and all good. Do to the nature of our setup the accounts are configured as non-cached mode.
Now we have *some* (so far about 10 our of 170) users who will open outlook and immediately be prompted for username and password. If the user types in correct username and password (domain\username) the prompt just reappears. If the user hits cancel outlook says "Server unavailable" and outlook bombs out. I should mention that exchange is, at all times, available. The same user which gets prompted for auth can login to OWA without issue.
Can i fix this? Yes - i can. By going to control panel > mail > Delete mail profile and start again. The wizard to add exchange account is re-completed and outlooks works immediately.
Obviously i do not want to have to do this, nor do i have any understanding why this is occuring to begin with since there has been no changes to the config of the exchange server recently.
Any comments and assistance very welcome.
Thanks all!
