Problems with Calendar invites and gmail?

Problems with Calendar invites and gmail?

Hi there

Sorry of this is a well documented topic...

I successfully invite multiple users to an event
and I receive their email responses but only some
of these people's responses are shown in the
calendar event itself.

So I receive an email notification that they are
attending (or not attending) but the calendar
event still shows some of them as having
NOT responded.

Any ideas please?

It seems to be mainly SOME gMail users (but not all)!

Thanks

Dan
