Hi，@Mytoast Admin

Thanks for posting your question in the Microsoft Q&A forum.

You want to access M365 group mailboxes, mail-enabled security group mailboxes, and public folder mailboxes through PowerShell. What information do you want to check in your mailbox?

The following is the cmdlet for querying basic mailbox information.

1. Returns information about all Microsoft 365 groups, display names, email addresses，Owners and Privacy.

Get-UnifiedGroup | Format-List DisplayName,EmailAddresses,ManagedBy,AccessType

2. This example show the members of the Microsoft 365 Group named Group2.

Get-UnifiedGroupLinks -Identity "Group2" -LinkType Members

3. Access the mail-enabled security group mailbox named "Test5/30".

Get-DistributionGroup -Identity "Test5/30" | Format-List

4. Access the public folder.

Get-Mailbox -PublicFolder

Hi，@Mytoast Admin

I'm glad to hear from you. I have understood what you are saying.

Generally speaking, PowerShell cmdlets can be used to manage and view some properties of Exchange mailboxes, but cannot directly view the specific email content in the mailbox.
