If you use Microsoft 365 and Paubox's Encrypted Email and/or Inbound Security solutions but are parting ways with Paubox, you'll need to follow these steps to return your email to its original routing.

Part I: Your Domain - Update DNS (SPF) Record

1. Log in to your Domain Host
2. Click on the Control Panel (may also be called DNS Zone Editor, or just DNS)
3. Find the record of type TXT with a value similar to: v=spf1 include:_spf.paubox.com include:spf.protection.outlook.com -all
4. Edit the record and remove only "include:_spf.paubox.com" from the value (leaving the rest of the record in place)
5. Click Save

Part II: Exchange Admin Center - Remove Paubox connector

You will need to use the Microsoft 365 Exchange admin center to remove the Paubox mail flow connector. Here’s how you do it:

1. Go to https://admin.exchange.microsoft.com/ to access the Exchange admin center. If you haven’t logged in already, you’ll need to do that first in order to be granted access.
2. On the left menu, mail flow and then connectors. 
3. Find the Paubox connector and Delete it.
4. Click Save if necessary.

That's it! Thanks for using Paubox - please feel free to reach out to us with any questions, or if you'd like to re-visit Paubox down the road: support@paubox.com
