How to: Pulling Exchange Settings From Office 365 Using Powershell

 

This document describes the process of grabbing all mailbox settings from Office 365 Exchange. We use this process a lot for troubleshooting on the back end.

Starting Session with O365:

1. Open up the Azure active directory module PowerShell instance.
2. Store credentials in an object:

   PS C:\WINDOWS\system32> $UserCredential = Get-Credential
   
   cmdlet Get-Credential at command pipeline position 1
   Supply values for the following parameters:
   Credential
   PS C:\WINDOWS\system32>
   

3. Create session object, utilizing credentials:

   PS C:\WINDOWS\system32> $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.of
   fice365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
   PS C:\WINDOWS\system32>
   

4. Now import session

   PS C:\WINDOWS\system32> Import-PSSession $Session
   WARNING: The names of some imported commands from the module 'tmp_ibt3qgi3.fcu' include unapproved verbs that might
   make them less discoverable. To find the commands with unapproved verbs, run the Import-Module command again with the
   Verbose parameter. For a list of approved verbs, type Get-Verb.

Get Mailbox Settings for User:

• Just check to make sure that box exists
• Pull all mailbox attributes by piping to field list (otherwise most will be hidden)
• Pulling Mailbox settings for Universal Messaging (Voicemail):

  PS C:\WINDOWS\system32> Get-UMMailbox -Identity $User_SIP_Address | fl
  
  
  RunspaceId                        : 0cc44215-d538-48d1-b1f3-80e80f1a2b69
  DisplayName                       : $Full_Name
  EmailAddresses                    : {eum:1111;phone-context=4-digit-plan.6cd0fac6-83bf-47c1-acff-f776a07bb8cb,
  ...
  

• Pull junk email settings for the given user

  PS C:\WINDOWS\system32> Get-MailboxJunkEmailConfiguration -identity $User_SIP_Address
  
  
  RunspaceId                  : 0cc44215-d538-48d1-b1f3-80e80f1a2b69
  Status                      : IsPresent, IsEnabled
  Enabled                     : True
  TrustedListsOnly            : False
  ContactsTrusted             : True
  TrustedSendersAndDomains    : {}
  BlockedSendersAndDomains    : {}
  TrustedRecipientsAndDomains : {}
