We have set up Office 365 Groups within CRM but when we create the new Office 365 group, within CRM it just shows a "Sign in to office 365" window and if you click "sign in" a smaller browser window opens and hangs.
We can access the Group from within Outlook in o365 but not from within CRM.
Any suggestions on how to fix this?
I am logged in as admin in CRM, have tried in Edge, inprivate Edge, IE and inprivate IE and still no luck
