Dear Forum,
I am running Office 2016 for Mac in the latest Version. My goal is to share and edit a document with other Users (Using Office 2010 for Windows).
Microsoft help says, an invitation has to be send per Mail and everything is fine after then.
Problem: None of my invitation-mails arrive.
Question: Do my friends have to meet special requirements in order to get an invitation mail?
Would be very happy for an answer.
