Write Microsoft Teams Number to OnPremise AD

Let’s perform Teams Magical Spell Today which has been requested by Customer’s Telecom Team.

Requirement is to Write the Microsoft Teams assigned number to Onpremise AD attribute i.e. Business Phone.

PowerShell Script shared in this post will fulfill the requirement.

Parameters Used:

##################################################

[Parameter(Mandatory = $true)]

[string]$domain,

[Parameter(Mandatory = $true)]

[string]$ADattribute,

[Parameter(Mandatory = $true)]

[ValidateSet(‘True’,’False’)]

[string]$reportonly,

[Parameter(Mandatory = $true)]

[int]$countofchanges

#################################################

$domain : Your tenant name for example techwizard.onmicrosoft.com àtechwizard is the value that needs to be entered here.

$ADattribute: Attribute in Active directory that you want Teams assigned number to be written for example: telephonenumber

$reportonly: True or False (True if you want that it should just report and False if you want it to write to active directory)

$countofchanges: This is threshold, it depends on environment (first time you can make it large enough to process everything and after that on subsequent run you can select the lower number)

Modules used:

Skype for Business online
Azure AD
Active Directory (It is part of remote server administration tools )

Script will generate CSV report which will show the telephone numbers that are already present, that are updated and accounts that are not found in local AD (may be because these are cloud only)

It will also generate detail log inside the logs folder.

Download the script from Github or install it from Powershell gallery.
