Hi,
This is weird but my Outlook is working fine now!
Thanks
This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
Hello,
After upgrade exchange server to the cumulative update 22 (CU22), all users receive the following error in Outlook: Outlook requests data from the server.
We check the status of the update and everything seems fine. In the server's Eventviewer, only the information logs.
This is strange because OWA and ECP work fine! The problem is in the Outlook connection and exchange.
Thanks
