I'm looking to delete the oldest 1 or 2 years emails, which might be some 16000 emails, and hard to use this Powershell command of 10 emails deleting.ġ. As I'm working with Microsoft engineer, the powershell command he tried is deleting only 10 emails at once. Mailbox full message already showing some 49.4 GB full, still receiving emails, I'm confused how different it is from the normal mailbox?Ĥ. Before taking any actions on this Group, I would like to have a backup of the emails of this Group, can some direct me to any non-powershell option prefarbly? any tools? free or free trial to manage?ģ.

Does deleting emails from O365 Group affect any of members Mailbox? I mean, if an email sent on a group, and all members received it, and when I delete the same email from Group Mailbox, does it delete from member Mailbox? Even if I Checked 'Send copies of group conversations and events to group members'?Ģ.

I'm not familiar with PowerShell to explore and do things.ġ. I looked around, but don't find proper options/solutions for me. Recently, all of the members from one O365 group started receiving Group Mailbox full email.
