I just finished setting up an active directory server 2012 to replace our 2008 server. I used the FSMO roles to make the new server the primary server. I'm having an issue with Microsoft Excel documents (we use Office 2010) opening in read only for most users. No one else has the document open, and there is no way that I can see to make it editable. The user has security rights to make changes and could make changes on the 2008 server. Any ideas?
