Restore user mailboxes (mailbox recovery) in Exchange Online

1. Install Azure AD Module
2. Open the Microsoft Online Services Module (shortcut from the desktop)
3. Run: $cred=Get-Credential.
   
   Note

   When prompted for credentials, type your Office 365 administration account credentials.

Solution:
Restore the AD user and run directory synchronization, which will “soft match” the AD user object and the Azure AD object, including reconnecting the “soft deleted” mailbox.

1. Connect to Azure AD PowerShell. In the same PowerShell window, connect to Exchange Online remote PowerShell
2. Restore the onPremise AD User
3. Run a Delta Directory Sync
4. Apply a new exchange online license to the newly created Azure AD object
5. Use the New-MailboxRestoreRequest to merge the content of the “soft deleted” mailbox to the active mailbox. See an example in the screen capture below:
   
   
    

1. Connect to Azure AD PowerShell. In the same PowerShell window, connect to Exchange Online remote PowerShell
2. Attempt to delete mailbox using by using the Remove-Mailbox cmdlet on the affected mailboxExample: From the Exchange Online PowerShell, run: Remove-Mailbox 
3. If step 2 fails, skip to step 8
4. Restore the on-premises AD User
5. Run a Delta Directory Sync
6. Apply a new exchange online license to the newly created Azure AD object
7. Use the New-MailboxRestoreRequest to merge the content of the soft deleted mailbox to the active mailbox. See an example in the screen capture below:
   
   
    
   

Solution:

Restore Inactive mailbox and perform a “soft match”

1. Connect to Azure AD PowerShell. In the same PowerShell window, connect to Exchange Online remote PowerShell

2. Connect the Soft Deleted Mailbox to a new Azure AD Account with the steps below:
   

   1. If the tenant IS NOT using SSO (Single Sign-On), run the cmdlet:
      New-Mailbox -Name "UserName" -InactiveMailbox -MicrosoftOnlineServicesID UserName@contoso.com -Password (ConvertTo-SecureString -String 'Pa$$word1' -AsPlainText –Force)
   2. If the tenant IS using ADFS (Identity Federation), run the cmdlet:
      New-Mailbox -Name "UserName" -InactiveMailbox -MicrosoftOnlineServicesID UserName@contoso.onmicrosoft.com -Password (ConvertTo-SecureString -String 'Pa$$word1' -AsPlainText –Force)

3. Restore or create a new On-premises AD user. Ensure that the on-premises account’s Primary SMTP Address matches the Primary SMTP Address of the Office 365 object. Change the on-premises object’s address to match if it does not.

4. Using Azure Active Directory Connect to run a Directory synchronization will “soft match” the On-Premises account with the new Azure AD account.
   

1. Connect to Azure AD PowerShell. In the same PowerShell window, connect to Exchange Online remote PowerShell
2. Run: Get-msoluser -returndeletedusers -userprincipalname user@contoso.com |Select-Object ObjectID
3. Run: Get-mailbox user@contoso.com |Select-Object ExternalDirectoryObjectID, UserPrincipalName
   •If the Object IDs match from step 2 and 3, then follow continue to step 4
   •If the Objects ID’s do not match from step 2 and 3 please call support
   
4. Create a new On-premises AD user and ensure that the on-premises accounts Primary SMTP Address matches the Primary SMTP Address of the Office 365 object.
5. Ensure the UPN of the AD user object matches what was returned in step 3
6. Wait three hours for the account to replicate to the Online services
7. If the Mailbox did not reconnect please call Microsoft Support
   
   

1. Restore or create a new On-premises AD user and ensure that the on-premises accounts Primary SMTP Address matches the Primary SMTP Address of the Office 365 object.
2. Ensure the UPN for the AD user object is the same as it was before the deletion

Solution:

1. Connect to Azure AD PowerShell. In the same PowerShell window, connect to Exchange Online remote PowerShell
2. Run: Get-Mailbox -Softdeletedmailbox user@contoso.com |Select-Object ExternalDirectoryObjectID
3. Run: Get-Msoluser -ObjectID 
4. Check if the ExternalDirectoryObjectID values from step 2 and step 3 match.
5. If they do, soft-delete the Azure AD user by Running Remove-Msoluser -Userprincipalname user@contoso.com
   • • Run: $DelUser = Get-MsolUser -UserPrincipalName User@contoso.com -ReturnDeletedUsers
     • Restore-MsolUser -ObjectId $DelUser.ObjectId
6. After 5 minutes, restore the Azure AD user using the steps below: 
7. If the ExternalDirectoryObjectID values from step 2 and step 3 do not match, it means there is a duplicate Azure AD user. Please contact support.

1. Login to the Office 365 porta at http://portal.office.com and check the user’s license status
2. Check to see if the user has a valid license. If user doesn’t have a valid license, apply an Exchange Online License.
3. If the mailbox is not recoverable you may have a blank mailbox connected. While it is unlikely that we can recover your data you can call into support.
   

1. Connect to Azure AD PowerShell. In the same PowerShell window, connect to Exchange Online remote PowerShell
2. Run: get-mailbox -identity User@contoso.com |Select-Object ExternalDirectoryObjectID
3. Run: get-msoluser -objectID < specify ExternalDirectoryObjectID from step 2> -returnDeletedUsers |select-object
4. Confirm that the MSOLUser is returned from step 3 and then, simply restore the deleted MSOL user back to an Active user using the steps below:
   • Run: $DelUser = Get-MsolUser -UserPrincipalName User@contoso.com -ReturnDeletedUsers
     Run: Restore-MsolUser -ObjectId $DelUser.ObjectId 
5. Login to the mailbox using the UserPrincipalName and verify you are able to access the mailbox.
   
   

1. Using the on-premises Active Directory Users and Computers, move the user to an Organizational Unit that is not filtered in directory synchronization. To determine the type of filtering setup in your organization, follow this article
2. Force delta synchronization 
3. After synchronization is complete, confirm that the user is present in Azure AD (through O365 admin center ->Active users). The mailbox will get re-connected to the Azure AD user automatically.
   

1. Connect to Azure AD PowerShell
2. Check License on the object using:
   get-msoluser -userprincipalname user@contoso.com |Select-object Licenses 
3. If license property doesn’t hold any value, the mailbox is not recoverable.
4. Using the on-premises Active Directory Users and Computers, move the user to an Organizational Unit that is not filtered in directory synchronization.
   To determine the type of filtering setup in your organization, follow this article
5. Run a Delta Directory synchronization
6. Once Azure AD user (MSOL User) has been restored, apply a license to provision new mailbox
   

1. Connect to Azure AD PowerShell. In the same PowerShell window, connect to Exchange Online remote PowerShell
2. Next, determine the state of the soft-deleted mailbox.
   Run: Get-mailbox –softdeletedmailbox –identity "<UserPrincipalName of the user>" |select-object IsInactiveMailbox
3. Based on the value of IsInactiveMailbox, take the appropriate steps:
   If IsInactiveMailbox is True:
   
   1. Run: Get-Mailbox "<UserPrincipalName of the user>" -softdeletedmailbox| Select Name, DisplayName, MicrosoftOnlineServicesID, ExchangeGuid 
   2.  Run: New-Mailbox -Name "<Name from Step 2>" -inactivemailbox "<ExchangeGuid from Step 2>" -MicrosoftOnlineServicesID "<MicrosoftOnlineServicesID from Step 2>" -Password (ConvertTo-SecureString -String 'Pa##w0rd goes here' -AsPlainText -Force) 
   3.  Using the on-premises Active Directory Users and Computers, move the user to an Organizational Unit that is not filtered in directory synchronization.
      To determine the type of filtering setup in your organization, follow this article . The Azure Active Directory user will soft-match to the on-premises Active Directory user.
   If IsInactiveMailbox is False:
   
   1. Run: Undo-SoftDeletedMailbox user@contoso.com -WindowsLiveID user@contoso.com -Password (ConvertTo-SecureString -String 'Pa$$word1' -AsPlainText -Force)
   2. Connect to Azure AD PowerShell 
   3. Run: get-msoluser -userprincipalname user@contoso.com
   4. Once you verified that the MSOLUser is returned in the previous step force a delta sync from on-premises Active Directory. It will soft-match to the user in Azure Active Directory.

Solution:

1. Force a delta synchronization to sync the on-premises Active Directory user to Azure Active Directory
2. If in an Exchange Hybrid environment
   1. Provision an Exchange Online mailbox for the user
      Enable-RemoteMailbox "UserName" -RemoteRoutingAddress "User@contoso.mail.onmicrosoft.com “
   2. Assign an Exchange online license to the user through the Office 365 portal.
3. If not in an Exchange Hybrid environment, simply assign the Exchange Online License for the user
