I am having an issue with our Outlook clients after migration to Exchange 2013 from Exchange 2007. The clients keep asking for Credentials, even after selecting remember password. So I click cancel, and on the send/receive tab there is a button
that is requesting Username and Password. I click it and it appears to connect. It says it is connected and then either I wait a few minutes and there will be another credentials popup, or I try to send out a mail message and get the same thing.
I'm not having issues with internal clients. And our certificate is working fine. testexchangeserver.com Outlook Anywhere passes. All settings on Client Outlook match. Outlook versions are updated to recent version, 2007 and higher.

Also noticing that every once in a while the Authentication settings under Security tab in the More Settings portion of setup, keep changing to Anonymous. The settings within Exchange Proxy Server also keep changing to negotiate.
I would have like to use NTLM across the board so my mobile users do not have keep entering their information. When I do get the settings changed to NTLM it appears as though it stays connected a little better, but that is until I send a message or if I restart Outlook.
I have been working on this for DAYS and tried every single thing I can think of finding: from changing the settings, rebuilding the autodiscover settings, reinstalled outlook, setup outlook profiles, deleted outlook completely including profiles and many
more things. Has anyone ran into this, and what can I do. I would like to just redo the RPC virtual directories to see if that helps, but cannot find information anywhere. Reinstalling Exchange is NOT AN OPTION as I have already moved the
boxes because it appeared to be working and worked fine in my test environment.
Really hoping someone can help, let me know what else you need. I have to get this going, as I have sales people without mail. I had to move the boxes, as they for some reason were not able to connect to their old boxes after I installed the Exchange
2013 and it was a big mess. Figured it would be easier to move everyone to what I thought was working fine, and ended up being a big mess.
