Invitation reject?

Question

As a moderator of a group I invited somebody to join and got the following message:

"Sorry, we were unable to deliver your message to an ....@hotmail address.

Remote host said: 550 SC-001 Mail rejected by Windows Live Hotmail for policy reasons. Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation problems. If you are not an email/network admin please contact your E-mail/Internet"

Why was that rejected? And what have I to do to invite that person?

Answer 1

hotmail is rejecting them since they see invites as spam. if you have a closed group, you're stuck unless the person wants to use a different addy

if it's not a closed group, send them the link to your group and they can join per the great big Join This Group tab
