Office365 Powershell One-Liner: Find Emails Stuck in Users’ Outboxes

I wrote this quick and dirty one-liner to help monitor and find stuck emails in Exchange / Office365 mailboxes across a tenant and export the list as a CSV.

Get-Mailbox -ResultSize Unlimited | Get-MailboxFolderStatistics | Where-Object {$_.Name -eq "Outbox" -and $_.ItemsInFolder -gt '0' } | Select-Object Identity, FolderType, ItemsinFolder, FolderSize | Export-CSV "C:\CSVs\Outbox.csv"

Easily Enable Active Directory Recycle Bin in Windows Server 2012 R2

I recently enabled Azure Active Directory (AD) Connect and wanted to turn this feature on. After doing some reading, I found a simple way to enable the AD Recycle Bin.

  1. In the management console, go to Tools > Active Directory Administrative Center
  2. Select Local Domain and in the Tasks Pane
  3. Select Enable Recycle Bin.
  4. Click OK

    NOTE: Be aware this feature cannot be disabled.

  5. Click OK.  Once enabled, wait for AD replication to complete as this is a change made on the configuration partition. This process may take a while should your organization have a large active directory infrastructure.

A very simple enablement of a process that could save you hours of restore time.  Again, this process cannot be reversed once invoked.

Empty the Recycle Bin for All Users with Powershell

On a new client’s server, I ran into an issue where a drive was running low on space and I found that another user account on the server (which had been deleted) had files in the Recycle Bin!

Thankfully, I found this Powershell command which worked to delete the files. All you have to do is open a Powershell console as admin and run the following command:

Get-ChildItem “C:`$Recycle.bin\” -Force | Remove-Item -Recurse -force

You can append -Whatif to do a test run and see what files will be deleted before actually deleting them.

How To: Disable Clutter in Office365

To disable Clutter in Office365 via Powershell, simply do the following:

Connect to Office365 Powershell for your account

Then simply run this command to disable Clutter for all mailboxes:

That’s it! If you want to disable Clutter for a single mailbox, you can do the following:

To do this via the Office365 Portal, just navigate to: Mail > Automatic Processing > Clutter and turn it off!

How to Find Last Logon Time for Exchange Mailbox Users

The last logon time of an Exchange 2010/2013/2016 mailbox user can easily be found by running the Get-MailboxStatistics cmdlet in the Exchange Management Shell.

 

You can further sort the info by including and running the following command:

Get-MailboxStatistics -Server EXCH | Sort LastLogonTime -Descending

And export it to a CSV by adding an Export-CSV option like below:

Get-MailboxStatistics -Server EXCH | Sort LastLogonTime -Descending | Export-CSV c:\lastlogon.csv
