I have an environment running Exchange 2013 which migrated from Exchange 2010. Some of the users has been asked for change password after Outlook has launched,
Our environment are using both Outlook 2010 and 2013, this happened for both Outlook 2010 and 2013.
The message asking for changing password show in the outlook windows right conner. But when the user click to it, the message is gone and the user is working as normal.
It happened randomly, could you please guide me how to fix this annoying problem? Thank you.
