Connect the 'Limit availability to specific users' to a dynamic distribution group
Currently the only option to limit the availability for an Outlook Add-in I found is this: https://technet.microsoft.com/en-us/library/jj943757(v=exchg.150).aspx
But this PS takes actually a copy of the users in the distribution list. When people leave or enter a company and get included in the distribution list then they don't get the Add-In and the script must be executed again.
Please extend this or provide another easier (no lets run a script every day) way to limit the availability to specific users.
Without scoping, buttons in the ribbons cannot be used in our company. We don't want everyone too see all applciations. Scoping is needed...

Maybe MS can build in an option to use a scope?
