How to send mail from or on behalf of an O365 group


This how-to explains how to send email from or on behalf of an O365 group.

Please see this support article from Microsoft:

Send email from or on behalf of an Office 365 group


Be default, group members and owners cannot send mail as or on behalf of an O365 group and this is not a setting that can be managed by a group owner.

If you need to send mail as or on behalf of a group, please submit a helpdesk support request after creating your group and specify who needs to send as or on behalf of the group.
