Outlook SSL Certificate warning

Hi,

We just moved a client to Office 365 from GoDaddy POP email, so never had an Exchange server and no email certificates.  Now every time they open Outlook (various versions, happens to all) they get the SSL Certificate warning and you have to hit yes.  The warning was for a self-signed cert called Sites.  I have removed it/deleted it from the server and on a test machine, but it still pops up?  Does anyone know how to make it stop?

Thanks,
Rob

Hi,
If you did a migration from Godaddy to Exchange online(Office365) you dont need a certificate.
You just make sure there is no HTTPS traffic scanning enabled in your firewall.
You can try testing https://testconnectivity.microsoft.com/  Office365 outlook connectivity.

Thanks

Hi,

Not sure what you mean, I know I don't need a certificate, and the one that is popping up in that message has been completely removed from the server, so not sure why Outlook is still having it popup?

I actually found a registry change to make to ignore the alert, so we are good now.
