I'm trying to track down an certificate error on most of our machines. When outlook opens, version doesn't seem to matter, an error saying the name on the security certificate is not valid. The name on the certificate is EXCHG03.ourdomain.com. We use office 365 as our exchange hosting but the error indicates we use to have an exchange server. Digging through AD Sites and Services, I found references to Microsoft Exchange in the services section. I also found references to EXCHG03 under the Microsoft Exchange section. I found the following article http://techhead.co/removing-exchange-from-active-directory/ doing previous searches for a fix, but I'm worried if I try this it will effect our current office365 exchange server.

Does anyone know if this would be safe? Will it solve the issue of outlook security certificates?

I believe the exchange server was 2003.
Currently have 2 AD servers, with a 2008 R2 system as FSMO master and the other system 2003.
Desktops with the issue range from XP-Win7 and Outlook 2003-2013.
