I've been doing some investigating and apparently a user's birthday date (the one that shows up on Delve) is not stored in a property inside the user's own office365 account object.

I'm trying to create a PowerShell script in Azure where I can update a user's birthday with a value that is currently in a SharePoint list. As of right now if I could find out how to even set the birthday property hard-coded, that would be some progress.

Get-MsolUser and Set-Msoluser don't work because as I stated previously the birthday date isn't there for some reason, but I can retrieve a user's birthday utilizing Microsoft Graph and sending a GET request to this URL of the API https://graph.microsoft.com/v1.0/users/{user_id}/birthday.

The response of that request is what I would like to be able to automatically set, but I can't seem to find a way to do so.

  • I believe I found the answer to my question here: docs.microsoft.com/en-us/graph/api/… will update if it works

  • Did you try this? Do you want to perform this using PowerShell or Microsoft Graph? Jan 14, 2021 at 15:56
  • I saw that but didn't follow through because I didn't think that Delve and SP user details would be connected, I was only looking for office365 user properties.

  • And I want to perform it with powershell, but if cmdlet didn't exist I was considering creating a script to invoke a rest method and patch the birthday dates that way

You can set the birth date using Set-PnPUserProfileProperty in PnP PowerShell.

For Example:

Set-PnPUserProfileProperty -Account '[email protected]' -PropertyName "SPS-Birthday" -Value "01/14/2020"


enter image description here

Update from comments:

I tried running the graph query https://graph.microsoft.com/v1.0/users/{user_id}/birthday. This also returns the same birth date:

Update Birth date using Microsoft Graph:

Method: PATCH

  • Would this update the Delve "birthday" property as well?

  • Yes it will. Check the command I used and the output in updated answer. Jan 14, 2021 at 16:21
  • This sets the value to the UPSA which isn't a Graph query, what the OP was asking about. UPSA will be going away so I'd suggest the Graph route.

  • This is one-time thing that I need to run in order to update our employees' birthday dates @TrevorSeward, do you recon the graph approach is better? One problem I found is that my account doesn't have access to change other people's properties. Is there a workaround for that?

  • I tried running the graph query https://graph.microsoft.com/v1.0/users/{user_id}/birthday. This also returns the same birth date as I set using PnP PowerShell. see updated answer. To update the user profile properties of other users, you will need administrator permissions. Jan 14, 2021 at 16:34

It finally worked. Here's the code to change one single user's birthday date (...where $creds name is the name of a credential created on the azure automation account used to run the script, with full sharepoint admin privileges given on the admin site (the same site used as url)):

Connect-PnPOnline -Url https://xxxx-admin.sharepoint.com/ -Credentials $creds

Set-PnPUserProfileProperty -Account '[email protected]' -PropertyName "SPS-Birthday" -Value "01/14/2020"```
