Block Users from adding an E-mail account
Hi Everyone.
I'm trying to block all our users from being able to add a personal E-mail account(webmail, Gmail etc) on the outlook client but i'm not sure if i can block this from the firewall.

Hi Thobela
This should be doable by combining application control with destination fqdn or ISDB.
E.g.:
Enter your E-mail address. We'll send you an e-mail with instructions to reset your password.
