We have 2 servers running Exchange 2013.
Everything seems to be working without problems for the email associated with the Windows account (domain joined)
However if I try to add in Outlook a second account it asks for the credentials every time outlook is restarted (tested in outlook 2010 and 2013)
I also noticed that for the email associated with the windows domain account, in the Security tab, the Logon network security is set to Negotiate and the Encryption is activated.
For the other account it always reverts to Anonymous Authentication.
How can I fix this so the credentials are saved and Encryption is activated?
