[Evolution] Office365 multiple shared calendars from an account

[Pete Biggs <pete biggs org uk>]

Hi -

I've been subscribed to a single shared calendar from a delegated
account on an Office365 tenancy for a long time.  The account has just
added another calendar that I need to use and I can't work out how to
subscribe to it.  Any hints?

I can see the new calendar fine in OWA and Outlook so I have all the
correct permissions.

P.
