- Cause 1: Autodiscover isn't configured correctly for the domain suffix.
- Cause 2: Users don't have the correct licenses.
- Cause 3: Group creation is disabled through the Outlook Web App (OWA) policy.
Resolution for Cause 1:The Modern Groups feature uses the domain in its primary email address when it contacts Autodiscover. By default, this domain is *.onmicrosoft.com. To resolve this issue, configure Autodiscover to allow Outlook to connect to the group.
Resolution for Cause 2:To view and participate in groups, users need both a OneDrive for Business license and an Exchange Online license. If a user isn't licensed correctly, advise them to contact their administrator to resolve the issue.
Resolution for Cause 3:An administrator may have disabled the permission to create groups. This permission can be disabled through the OWA mailbox policies. For more information about how to administer modern groups by using Remote PowerShell, see Use PowerShell to manage Office 365 Groups.
