I am using an exchange hybrid environment for the security group I created (onprem). I wish to know whether it is possible to move the group towards being a mail-enabled security group. Also, can such a group be migrated to the cloud?
If you have Universal security groups, then YES, you can convert them to mail-enabled security groups and can be migrated to the cloud. It will also be used to send email to users in that group. If your group type is not universal Just change the group to universal. Shouldn’t be an issue.
And then add the email to the email field and be sure to add MTP:email@example.com to the proxyAddresses attribute. Sync to 365 if that’s your provider.
