I tried to invite someone into a group conversation yesterday, and it\nimmediately bounced, with a message saying that the "Invitation could not be\ndelivered"\nOthers in the group have had the same problem with this particular account.\nI checked with her today, and she has not blocked any of us (and I believe\nher). And we did have a one on one chat today.\n\nAny idea what might have produced this kind of invitation decline, without\nany knowledge on her part, on multiple occasions? We work as a design team\nfrom different cities, bringing someone into a chat is often important, and\nwe'd like to figure this out.\n\n\nAnd while I'm here, is there a reason why the Messenger Help Search can't\nseem to find particular error messages? On more than one occasion, I've had\ntrouble connecting, and when I've gone through the troubleshooting guide, it\ndoesn't seem to recognize the error message number it is giving me. (For\nexample, today, I had Error 81000377 Contact list could not be accessed -\-\nI couldn't find a thing on this. I tried flushing the DNS cache, and\neventually, I got in, but really -\- why isn't there more info online?)\n\nThanks for the insight!
