Hi everyone
Over the weekend our sec admin was applying patches to one of our Exchange 2013 servers (CU11). He mentioned that the Windows Updates failed and rolled back. I am still waiting for details from him on what exactly failed. OWA/Mailflow is functioning. The only strange thing is the page we're directed to after logging into ECP (Exchange Admin Center).
The Sec admin that applied Windows Updates and had to roll back can view the ECP page without any issues. The rest of the admins here see a page similar to the screenshot below after logging into the Admin Center. This lead me to believe it's permission
related? maybe something went wrong when the patch rollback occurred with permissions? I will continue to dig through logs and update this thread if I find anything.
Thank you in advance for your insight,
