Remove Invalid ProxyAddress From User Account RRS feed

  • Question

  • I stumbled on the script titled " Export User Names and Proxy Addresses to CSV File" (https://devblogs.microsoft.com/scripting/export-user-names-and-proxy-addresses-to-csv-file/) and I must confess that it is very good and seems to be the solution to the issue am facing.
    I have an Exchange server 2013 environment, I recently discovered that about 60% of the total mailboxes in the organization have three ProxyAddresses each. 
    First : SMTP: xxxx@domain.com
    Second : X.400 xxx

    Third  :  UserSamAccountName

    The issue

    Whenever  I tried to migrate any of the users/mailboxes with the three ProxyAddresses to another Mailbox Database, I get an error saying that the user account contain an invalid email address.

    Upon finding the script, I see that if I could export out the three ProxyAddresses to a CSV for all accounts, I have another script that can use the CSV as input and remove the third ProxyAddresses from all the affected Users/Mailboxes.

    I need your help on how to create a third column for ProxyAddress_3 using the script or any other method to resolve the issue.
