I will really appreciate any help on this please. :unsure: :unsure: :unsure:

Could you provide a screenshot or more information about what is happening. The meeting form includes three text boxes for name and email fields that can be used to search for contacts and users. The search results can be used to add invitees to the meeting. This section is located at the bottom of the edit meeting form.
