Windows – Can’t see messages in Skype

Your computer's noise reduction feature (assuming it has one) may be incorrectly telling Skype to cut out your outgoind sound. I am on a Mac, and have what seems to be the same problem, so here is what I am trying:

1. I did the "Echo" test to hear a recording of a call, and I could hear my voice cutting out.
2. I went in to System Preferences -> Sound -> Input tab
3. I turned off "Use ambient noise reduction".
4. I did another Echo call, and did not have the cutting out issue.

I don't know whether this will fix the issue the next time I have a long call, but it's at least something to try, if your system has a similar "automatic adjustment" feature that tries to reduce your background noise for callers.

You need one member of the group who is a friend with all of the other members of the group, and he has to start the group chat (by adding all the other members).

The friends status must be confirmed, ie the others must accept the request-just sending a request is not enough.

Also all the members' privacy settings must be set as the picture you uploaded in case any of them aren't friends with any other of the members.

Also refer here:

the user that you are trying to add to a group chat is not on YOUR contact list, so you cannot add them to any group chat.
