How to remove the MobilePhone from my Public Folder contacts?


In case you want to remove the "MobilePhone" property for all your public folder contacts, you can use this script. The same reasoning applies for other properties, with the mention that you need to load the corresponding extended property for them.

 

Prerequisites:

-The script requires EWS Managed API 2.2, which can be downloaded here: https://www.microsoft.com/en-gb/download/details.aspx?id=42951
-You need to be connected to Exchange Online when you run the script (copy/paste it into a Notepad file and save it with the extension ".ps1"): https://technet.microsoft.com/en-us/library/jj984289(v=exchg.160).aspx
