Accepting invitation as a Gmail User - Password does not work
In our case, previous external users invited from SharePoint show up with the #EXT# after their external mail, with the " @ " replaced with underline as bobafett_live.com#EXT#@constoso.com.
Now Guest users invited from Azure show up as bobafett_live.com@onmicrosoft.contoso.com .
Which in my opinion looks awful and their is no way to change the invitations with the free (O365) version of Azure. I even created a Support request to investigate.
BUT what an Admin can do is change the username in the O365 portal to use a semi-normal style of bobafett_live.com@contoso.com but the change has to be communicated to the external party outside of the Azure/O365 workflows because they cannot login after the change in the username until they are given the new one.
