Exchange 2013 Asking for Credentials
Hello,
I have a relatively new install of Exchange 2013 running on Server 2012. It has been up and running for about a month with no issues. I purchased and installed a cert from Godaddy about a month ago and installed it and, again everything was working fine. There are only 4 users. A couple of days ago it stopped working. All users upon opening Outlook or accessing their mail on their phones were asked the for the dreaded Windows Credentials”. Of course it does not matter what user and password you enter it does not connect. This includes the domain admin and password. When I went to look at the server I could not access the ECP. I had to go the IIS Manager, Default Site, and Bind both port 443 to the cert I installed from Godaddy. I can now access the ECP but I do not see anything unusual. All services are running. The event shows schannel errors. I have seen this before when there is a cert problem but this has been running for a month with no issues at all. Any help with this would be appreciated.
Thank you

Thank you Will. Yes, I tried a slick and reload of the active sync account and it will not connect. This is not only on the phones, there are 3 PCs that can longer connect as well.

I should note that the 3 PCs are hard wired on the same network as the Exchange server.

I see you are from Kitchner. Do you know a Robert Joliffe?

I have attached a screen print of one of the PCs when they open Outlook. Please note the Connect to address.

I ran the Outlook Connectivity test and I have attached the results in a html file.
Have you tried to check the IIS logs which are located in the default directory c:\inetpub\logs\logFiles\W
I would then use the following link below which will identify what the ActiveSync error codes mean.

That will give you a good starting point for troubleshooting.
