Reset redemption status for a guest user (Preview)

After a guest user has redeemed your invitation for B2B collaboration, there might be times when you'll need to update their sign-in information, for example when:

  • The user wants to sign in using a different email and identity provider
  • The account for the user in their home tenant has been deleted and re-created
  • The user has moved to a different company, but they still need the same access to your resources
  • The user’s responsibilities have been passed along to another user

To manage these scenarios previously, you had to manually delete the guest user’s account from your directory and reinvite the user. Now you can use PowerShell or the Microsoft Graph invitation API to reset the user's redemption status and reinvite the user while retaining the user's object ID, group memberships, and app assignments. When the user redeems the new invitation, the UPN of the user doesn't change, but the user's sign-in name changes to the new email. The user can subsequently sign in using the new email or an email you've added to the otherMails property of the user object.

Reset the email address used for sign-in

If a user wants to sign in using a different email:

  1. Make sure the new email address is added to the mail or otherMails property of the user object.
  2. Replace the email address in the InvitedUserEmailAddress property with the new email address.
  3. Use one of the methods below to reset the user's redemption status.


During public preview, we have two recommendations:

  • When you're resetting the user's email address to a new address, we recommend setting the mail property. This way the user can redeem the invitation by signing into your directory in addition to using the redemption link in the invitation.
  • When you're resetting the status for a B2B guest user, be sure to do so under the user context. App-only calls are currently not supported.

Use PowerShell to reset redemption status

Install the latest AzureADPreview PowerShell module and create a new invitation with InvitedUserEmailAddress set to the new email address, and ResetRedemption set to true.

Uninstall-Module AzureADPreview 
Install-Module AzureADPreview 
$ADGraphUser = Get-AzureADUser -objectID "UPN of User to Reset"  
$msGraphUser = New-Object Microsoft.Open.MSGraph.Model.User -ArgumentList $ADGraphUser.ObjectId 
New-AzureADMSInvitation -InvitedUserEmailAddress <<external email>> -SendInvitationMessage $True -InviteRedirectUrl "" -InvitedUser $msGraphUser -ResetRedemption $True 

Use Microsoft Graph API to reset redemption status

Using the Microsoft Graph invitation API, set the resetRedemption property to true and specify the new email address in the invitedUserEmailAddress property.

Authorization: Bearer eyJ0eX...  
ContentType: application/json  
   "invitedUserEmailAddress": "<<external email>>",  
   "sendInvitationMessage": true,  
   "invitedUserMessageInfo": {  
      "messageLanguage": "en-US",  
      "ccRecipients": [  
            "emailAddress": {  
               "name": null,  
               "address": "<<optional additional notification email>>"  
      "customizedMessageBody": "<<custom message>>"  
"inviteRedirectUrl": "",  
"invitedUser": {  
   "id": "<<ID for the user you want to reset>>"  
"resetRedemption": true
