In this post, we explore how to use PowerShell to create a report about distribution lists and their owners. The script is quick and dirty, but it works, and the code will run on both Exchange Online and Exchange Server and generates both HTML and CSV outputs. We also look at whether it’s possible to speed things up by using Microsoft Graph API calls. As it turns out, because we’re interested in owner information, it’s no faster to retrieve distribution lists using the Graph. However, as shown in a second script, the Graph is great at retrieving membership information.

You can configure Exchange Online distribution lists so that they reject messages sent to them as BCC recipients. I’m not sure how much use this feature will get, but it’s nice to have it anyway. PowerShell is the only management tool to configure distribution lists for the new block until Microsoft gets around to updating the Exchange Admin Center.

Now that we know all about the different email addresses used by Microsoft 365 Groups and Teams, the question arises of how to include a team channel as a member of a distribution group. As it turns out, there’s a simple way and a more complicated way.

Exchange Online distribution lists can be used to populate the membership of Office 365 Groups or Teams by applying a little PowerShell magic. Here’s how.

If you run a hybrid Exchange deployment, you probably have some on-premises distribution lists that you’d like to move to the cloud. Office 365 offers no way to do this, so it’s up to PowerShell. Instead of starting from scratch, you can use a script created by Tim McMichael of Microsoft and amend it to meet your needs. PowerShell is just great.
