Hi,<br />
<br />
I have started to migrated users from Exchange 2010 to Exchange 2016. Everything is working fine. I have only one issue..with Outlook. User migrated need are asked for credentials. They have a message. &quot;Your administrator has mad changes&quot;<br />
<br />
They need to introduce the passwor. It is by design?<br />
<br />
Or have I configured something incorrectly?<br />
<br />
Thanksss
