We have exchange 2010 and Exchange 2016, All the user mailboxes were moved to Exchange 2016. Now all the connections are redirected to Exchange 2016, Exchange 2010 will be decommissioned soon
After the mailbox is moved to exchange server 2016, We have noticed that any user has changed the password and logged in to domain joined computer and if they open the outlook, the new password used for windows login is not automatically taken for outlook, Instead outlook is asking for user to provide the password, after the new password is provided, the outlook profile is connected. Outlook version is 2016.
I have suspected this could be due to Negotiate authentication when using MAPI over HTTP protocol, So i removed the Negotiate authentication from Autodiscover, MAPI and EWS front end virtual directories in exchange server 2016, After this the authentication method used is NTLM, but the behavior is same when the user change the password and login to windows and open the outlook.
Please share your experience and thoughts on this.
How make the outlook client to get connect the mailbox automatically once the user has logged in to windows using the new password ?
