Hi Paul,

I wonder how you set up group, in Exchange Admin Center or Outlook client. If you directly click "New Contact Group", it will expand individual addresses when you send a meeting invitation, because it doesn't have own email address.

Meanwhile, enable cache mode in Outlook client and check again: https://support.office.com/en-us/article/Turn-on-Cached-Exchange-Mode-7885af08-9a60-4ec3-850a-e221c1ed0c1c.

If the issue persists, share a screenshot showing you send a emails to a group.

Regards,

Vanessa
