I'm using rackspace calendar for myself, along with two colleagues.

I'm unable to send an invite for meetings to my colleagues in the calendar - whenever I create an event, and add the person I want to the "Invite" (via their email address) - I get an error message after sending that tells me;

"An error occurred while sending invitations. Please try again shortly."

I've had this error for three weeks.

Any similar experiences or knowledge of why this could be happening please?


Please help….


I didn't find the right solution from the Internet.
