Hi all,

I would like to know whether there's a possible way to centerally manage
outlook add-ins for all clients. meaning enabling all add-ins for outlook
clients (by GPO for example).

Actually, what i would like to do is to limit the connection to exchange
server only to outlook clients that run the add-ins, and that is because
our add-ins enforce some business logics that users will be able to
by-pass without the add-ins.

i will appreciate any simple/creative solution.

Thanks, Kevin.
