My customer has a user base of Outlook 2007, 2010 and 2013. I need to disable Outlook signatures.
For Outlook 2007 and 2010 I can use the ADM templates.
I cannot find any ADM templates for Outlook 2013, only ADML and ADMX.
The customer's existing GPO structure uses the Classic ADM templates extensively. I realize these can be upgraded to ADMX, but do not want to impact the infractructure to do a conversion of all their templates and leverage the central store.
Instead, I would like to GPO a reg hack to disable the signatures only for Outlook 2013 and use the ADM templates for 2007 and 2010.
My question is what are the registry settings to do this in Outlook 2013?
