Hi there, my name is***** few questions for you:
1) If this is something new that just started happening, what's different about how Outlook used to work and how it works now. For example, have you added any plugins to Outlook such as Live Search Map? If so, please disable the add-in and retry it in Outlook. Some plugins have been known to cause that type of problem.
2) It looks like you already know one work-around, which is forwarding the meeting request, if you're the meeting organizer.
3) Another workaround is to go to the Scheduling Assistant, add the name of the person you want to add to the meeting where it says "Click here to add a new name," and then uncheck everyone else. When you click Send, it should only send to those who are checked.
Please give these things a try and chat me back to let me know if it fixes the problem. If it doesn't, I have a few more things to ask you. Thanks!
