Is it possible to add an external guest member to an office 365 group from the outlook 2019 client , NOT the outlook web interface ?
We can add external members to groups from OWA , not when we try via outlook 2019 we get a message about this operation being prohibited due to organizational policy. As the admin I haven’t found any explicit setting to block guess group additions from only the outlook client, since we can add them via owa. Is this just a bad error message and it is impossible to add external group members via outlook , or is there some outlook client specific setting to allow this . No one in our organization uses owa, so it is cumbersome to have to connect to owa just for this purpose.
