External users who do not have an @usca.edu email account can be added to a 365 Group.
NOTE: You must be a Group Owner to add an external user.
To add an external user to a 365 Group:
Sign into Office 365 and navigate to your Group
Click the "members" link as shown below (1)
Click "Add members" (2)
Enter the email address for the external user into the search box (3)
Click the address in the dropdown (4)
Click Save to add the user (5)
The external user will be sent a welcome message like the one shown below
If the external user has already signed into another USCA 365 Group, they can use the same password they used previously. If they have never signed into a USCA 365 Group with the listed email address, they will be prompted to set a password.
