We have had customers report that all shared calendars disappeared in 6740. In 6744 - installed this morning, the customer can see personal calendars, and attempt to re-share shared calendars, but it only lasts for moments and then this error (or similar) is produced:
Did not have shared calendar connections with; currentUser <a href='mailto:USER...
This is repeatable on all domains on the server that have shared calendars.
