[SOGo] Calendars locked

[Bob Wooldridge]

One of my users this morning has all their calendars locked.  Both their 
personal calendar and other calendars they are subscribed to. This is in 
Thunderbird (38.2) but the SOGo web interface seems to be working fine.  
If I try to sync or reload, nothing happens.

Any ideas what to do and what has caused this?
