So background, we used to have a exchange server on site, Last year we migrated Exchange Online and things have been good. Recently going through office renewals and we decided to go for Office 365 so I have been testing Office 2016 version. Upon installing and configuring Outlook 2016 I am constantly getting the following error every time outlook is opened. The domain it was trying to get the certificate for was for the old local exchange server.
I have to think it's the domain controller or group policy that trying to push the certificate down to individual machines as this is a new machine that was setup in the last month. I looked at my domain DNS and it's all pointing to the correct locations from what I can tell.
Any ideas on where I can look stop Outlook looking for this old outdated expired certificate?
