How to check your Office 365 tenant for auto-forward rules

Use the following steps to check for any Office 365 auto-forward rules to external email addresses.

In this blogpost I’m using Powershell to check for any existing auto-forward rules to external email addresses.

Step 1 Logon to Office 365 using Powershell

Step 2 Export the mailbox(es) that have either redirect or forwarding

This produces a list of all mailboxes that exist in the organization where the forwaring or redirect flags are enabled

Step 3 Investigate which rules are in use

Step 4 Remove the inbox rule from a specific mailbox

Step 5 Remove all the available inbox rules from all mailboxes (if you prefer)
