I'm using usual way for updating updates.php, but it looks that Integrator-31.0.3 doesn't call updates.php script when it is used in Thunderbird 52.

Will update them in the next few days.

With a user profile that previously used thunderbird 48 I can see the calendars and the address books (though, as the original report says, there are no subscription buttons).
If I create a new profile (my provisioning scripts generate a profile with the minimum account data, thnderbird fills in the gaps) I cannot see the address books and the calendars.

With Thunderbird and active Inverse SOGo Connector 31.0.3 it is not longer possible to move contacts between address books (local address books doesn't work also any more)

With Thunderbird 52.0.1 and SOGo Integrator 31.0.3. Thunderbird dosen't sync anything on startup. Calendars and adressbooks which were created before the 52.0.1 update won't disappear, but they won't sync new entries either. At this point the integrator is basically unusable, since there is no way of downgrading to an older thunderbird or lightning version.

Fixed!

We'll release new extension with next week's release of 3.2.9.
