Hello @Swearingen, Chase
It is possible to update cell phone contacts in Office 365 based on email distribution lists. One way to do this is to use the Office 365 Management API to programmatically update the contacts in the global address list (GAL).
Here are the general steps you can follow to update cell phone contacts in Office 365 using a distribution list:
- Create a distribution list in Office 365 for the users whose cell phone contacts you want to update.
- Create a list of the cell phone numbers and names you want to update in the distribution list. You can do this in a spreadsheet or other data source.
- Use the Office 365 Management API to retrieve the current contact information for the users in the distribution list. You can do this by making a GET request to the /users endpoint.
- Update the cell phone numbers for the users in the distribution list based on the data you created in step 2. You can do this by making a PATCH request to the /users endpoint.
- Repeat this process as needed to update the cell phone contacts for the users in the distribution list.
Good luck!
