I have a number of clients with a large number of thunderbird users who have been using it and zimbra with zextras for quite a long time (decades, as far as Tbird goes). A couple of these will soon have an urgent need to use 2FA, due to professional and insurance requirements.
I have been unable to find a clear path to this goal.
Any recommendations? Users are a mix of Mac, Windows and Ubuntu. Zimbra versions are current flavours of 8.8.15_whatever. Zextras is typically a perpetual license, version 3.1.2 is showing for one of the clients that will need action soon. Happy to upgrade/change licenses.
Thanks in advance!
