[Office 365] Delete a user account sitting in Recycle bin

Normally, user accounts that are deleted within Office 365 sit in “The recycle bin” where they can be recovered if needed. You can’t, however, delete users from that gray area within the web GUI. If you wanted to, say, delete and remove the license from a user and create a non-licensed shared mailbox, you’re boned without emptying it from the recycle bin first.

Before you start,you’ll need Microsoft Online Services Module for Powershell


To remove a specific user account from the Recycle Bin

  1. Connect normally, except add in connecting to the MSO server
    1. $LiveCred = Get-Credential
    2. $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $LiveCred -Authentication Basic -AllowRedirection
    3. Import-PSSession $Session
    4. Connect-MSOLService -Credential $LiveCred
  2. The ReturnDeletedUsers switch returns accounts found in the recycle bin. To return all:
    1. Get-MSOLUser -ReturnDeletedUsers
  3. If you find the account you want to remove, it’s a simple cmdlet to do so: where “Email Address” is the upn of the actual account
    1. Remove-MSOLUser -UserPrincipalName “Email Address” -RemoveFromRecycleBin
  4. If you’re removing an account in order to recreate it, you’ll have to wait 5-10 minutes before O365 will allow you to recreate over the deleted account.

If you don’t have a problem nuking them all, you can empty all via piping the get to the remove

#Haven’t tested this one; have a nagging you may need to fill an array and foreach through all the elements actually.

Get-MsolUser -ReturnDeletedUsers | Remove-MsolUser -RemoveFromRecycleBin -Force


Common PowerShell Commands for Office 365

Here are some commands that are handy to use for Office 365.

#Assign user credentials to variable “LiveCred”

$LiveCred = Get-Credential

#Connect to your Cloud-hosted Exchange using the credential stored in #LiveCred

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $LiveCred -Authentication Basic -AllowRedirection

#Import Cmdlets

Import-PSSession $Session

#Close your session

Remove-PSSession $Session

#Grant Bob Barker calendar (or any folder) rights to Adam Sandler’s. The field within ” ” can be either the user principal name or primary alias
#Possible   rights:  Ownder, Publishing Editor, Editor, Author, Contributor, Reviewer, Custom
#Note: practice-wise (for your own mental check), the account being given access is normally to the right of the account to which you are assigning the right.

Add-MailboxFolderPermission -Identity “The.Dude:\Calendar” -AccessRights PublishingEditor -User “Test Guy”

#View permissions on a folder

Get-MailboxFolderPermission -Identity “The Dude:\Calendar”

#View all accounts that have mailbox access beyond SELF

Get-Mailbox | Get-MailboxPermission | where {$_.user.tostring() -ne “NT AUTHORITY\SELF” -and $_.IsInherited -eq $false}

#The export to a file version of above

Get-Mailbox | Get-MailboxPermission | where {$_.user.tostring() -ne “NT AUTHORITY\SELF” -and $_.IsInherited -eq $false} | Select Identity,User,@{Name=’Access Rights’;Expression={[string]::join(‘, ‘, $_.AccessRights)}} | Export-Csv -NoTypeInformation mailboxpermissions.csv

#Grant user Send-as to identity

Add-RecipientPermission <identity> -AccessRights SendAs -Trustee <user>

#View all boxes that have Send-as attributes on them

Get-RecipientPermission | where {($_.Trustee -ne ‘nt authority\self’) -and ($_.Trustee -ne ‘null sid’)}
