Here is the Graph documentation for the properties supported by a contact:

https://learn.microsoft.com/en-us/graph/api/resources/contact?view=graph-rest-1.0#properties. Business phones is listed as a string collection, so you should be able to pass a set of numnbers.

I’m on vacation for the next two weeks, otherwise I would look further.

I’m trying to create new contact records for employee emergency contacts. So need to add multiple phone numbers but it appears MSGraph v1.0 doesn’t support Assistant’s Phone and I’ve scoured the internet for example of how to update Business Phone, Business Phone 2, Business Phone 3, Home Phone, Home Phone 2 and so on without success.

Am I looking for something that doesn’t exist?

No idea. I haven’t done any research to know how to answer that question.

Hi Tony, that has worked! Thank you!

I think the issue that you might be running into is that the Mail Contact object returned by Exchange Online doesn’t include a mobile phone property. It has a Phone property, but not a mobile phone. Personal contacts of the type stored in your mailbox do support a mobile phone property. If you stored the mobile phone number in another property supported by the cmdlet, you’d be able to retrieve it.

Get-ExoRecipient -Identity Jack.Smith -PropertySet All | Fl *Phone*

Phone : +353 1 1947 144

I am trying to include mobile numbers in this script and getting intermittent results. I have added mobilePhone to the contact object but it’s not including them. Any ideas?
$ContactObject = @”

I updated https://github.com/12Knocksinna/Office365itpros/blob/master/PopulateOrgContacts.PS1 to make the check for existing mailbox contacts better. Maybe it will help.

That line just creates a PowerShell list object. It has nothing to do with creating contacts.
