I have just setup our company e-mail with a popular online e-mail provider. E-mails will be retrieved from the online server via Thunderbird installed on Windows 7 PC's. I wish to exercise administrative control such that Thunderbird will only connect to the particular account with the particular online e-mail provider I originally set it up with.
Which is to say, I want to prevent users from accessing their personal e-mail (e.g. Gmail, Yahoo, Hotmail, etc.) by simply creating new accounts on Thunderbird.
Is this possible? How to do it? Users are currently non-admin users with program access restrictions enforced via parental controls.
2Mozilla has group policy templates have you tried look at the group policies in that template to see if there is something that woud prevent users from linking other email accounts? – Ramhound – 2014-06-16T10:44:44.320
