Re: Do Microsoft Office 2013 patches apply to Microsoft Office 365?

From my understanding if you deploy 2013 using click-to-run, updates for office are automatic and cannot be managed.  If you deploy Office 2013 using MAK or KMS activation like you would have in 2010 updates are pushed out through whatever policies you have in place.
