Hi @MichaelT630 

 

A "quick and dirty" solution, could be to allow Gmail, generate the invitation and restrict Gmail again. The restriction applies only for the generation of the invitation.

 

Or you can restrict the possibility to invite external people to people who have the role "guest inviter":

- These people will be made aware

- A monitoring will allow to follow if guests are created for sensitive domains (like Gmail)
