      How to Execute Bulk Updates of Primary SMTP Address for Distribution Lists

      Like any mail-enabled object managed by Exchange Online, distribution list proxy addresses determine if Exchange can deliver messages to an object. Sometimes the proxy addresses aren’t correct or need adjustment, such as in the case when an organization wants to make sure that all distribution lists have primary SMTP addresses from a specific domain. This article explains how to use PowerShell to adjust the primary SMTP address when necessary.

    Get-DistributionGroup | ? { $_.PrimarySmtpAddress -like "*@contoso.onmicrosoft.com"} | % { Set-DistributionGroup -PrimarySmtpAddress "$($_.PrimarySmtpAddress.Split('@')[0])@contoso.com" -WhatIf }
