Office365 and subscribe via ics

8218967 shared this problem 1 month ago

I've subscribed to a publicly shared Office365 calendar (*ics), but the Mailbox calendar never imports the calendar items; additionally, when I refresh the calendar from Mailbox' Calendar app, it throws the following error:

ErrorThe supplied recurrence rule is invalid. Please correct the rule and try again.

So, is it something about Mailbox ... or Office365 ... that prevents the calendar from being refreshed?

The error makes it sounds like the iCalendar file is malformed or has a malformed or unsupported reoccurrence rule. You can try checking your iCalendar file in an online validator and see if that gives you more detailed information about the problem.
