How to Enable Users to Receive Copies of Email They Send to Microsoft 365 Groups

It might seem like a small thing, but some users are upset when they don’t receive copies of their messages sent to Outlook Groups in their Inbox. A new setting allows users and administrators to control if they receive copies of messages from groups, but only when the user is a subscriber to groups (Follow in Inbox is turned on). In this article, we explore how to set the EchoGroupMessageBackToSubscribedSender control via OWA options and PowerShell, and how to sign up to be a group subscriber by yourself or with a little help from an Exchange administrator.

How to Manage Client Read Receipt Settings in OWA and Outlook for Windows

A reader request asked how to force users to send read receipts. This is a client-side feature so the settings involved differ from client to client. We explore how to control them in OWA and Outlook for Windows. A mixture of PowerShell and system registry settings help create a solution. We’re leaving figuring out how to manage other clients to our readers.

Stopping Users Updating OWA Autosignatures

If an Office 365 tenant goes to the bother of creating nice OWA autosignatures for users, shouldn’t we also removed the ability to edit the signatures in OWA settings? RBAC seems like the right way to do the job, but in this case, the way RBAC restricts options by removing the right to run cmdlets or parameters means that the block affects other OWA settings. Fortunately, the Exchange developers thought of this and provide an option in OWA mailbox policies to save the day.

How to Update OWA Signatures with PowerShell

OWA stores user signatures in mailboxes, which makes it a lot easier for Office 365 admins to update signatures centrally with just a few lines of PowerShell and some HTML magic. OK, maybe more than a few lines… but it’s a lot less complicated than it is to mess around with the system registry and points the way to how Microsoft might introduce cloud signatures for all Outlook clients.
