I am using EWS (Exchange Web Services) to do various operations with outlook meeting item. One of the requirement is to fetch created meeting and identify if particular participant is mail group email address or individual attendee's email address.

I could get meeting item using FindItem / GetItem however, not sure about how exactly participant's type can be checked.

Can you please suggest if any such option available with EWS ?

Thanks,

You will need a GetItem to see the attendees of a Meeting as FindItem won't return that information. Once you have the recipients you can check the MailboxType property https://docs.microsoft.com/en-us/dotnet/api/microsoft.exchange.webservices.data.mailboxtype?redirectedfrom=MSDN&view=exchange-ews-api . If that doesn't work then try the FindPeople operation https://docs.microsoft.com/en-us/exchange/client-developer/web-service-reference/findpeople-operation. If you using Office365 then doing a Graph lookup is probably a better and eaiser option to find that information.
