After last LEAP software update Gnome Online Accounts complains about the
Exchange credentials being expired. Re-login fails due to "authentication
failure".
When configuring the exchange account using evolution itself and authentication
method set to NTLM, it also can't open the Exchange mailbox due to "401 -
Unauthorized".
The credentials however are correct and work correctly on a fresh Leap install
until all updates up to now are installed. Then it stops working with the
symptoms described.
According to zypper history log last packages updated where samba. (see
attached history)


Reproducible: Always

Steps to Reproduce:
1.Install fresh Leap 42.1 without updates
2.Add a new Exchange account to GOA
3.Check correct functionality using Evolution(-ews)
4.perform zypper update until all latest updates are installed
5.try to use Evolution to open the configured Exchange mailbox
Actual Results:  
Connection with mailbox fails due to 401 - Unauthorized

Expected Results:  
Opening the mailbox

This problem also seems to occur on opensuse 13.2
