About this article

In this article we will be creating and configuring connectors to route e-mails through the Templafy Email Signature Server in the Exchange Online Admin Center.

    Add the Templafy managed DNS SPF entry to the DNS records for each sending domain. To ensure the Email Signature Server is identified as authorized to process mail for your domains it is important to add the Templafy-managed DNS entry for your cluster region., [essprod0|essaue0|essuse0].templafy-ess.com, to the DNS SPF record for each domain that may be sending emails through the Templafy Email Signature Server for processing. nslookup -type=txt templafy.com An example (SPF Record): v=spf1 include:essprod0.templafy-ess.com -all SPF entry Configuration, Setup, and Verification.

  Outbound connector validation is REQUIRED for Microsoft Exchange (through Exchange Online Protection) to trust the connectors.

  • Provide an email address from inside of your domain.

  • Click [+]

  • Click [Validate]

  • There will be a three-step validation progress bar. This will take one to two minutes to complete.

  If the second step of the test fails. Check if other connectors are already configured that could be intercepting the incoming validation email. Add an Exception for the built-in senderO365ConnectorValidation@<yourrdomain.tld> to this other connector's mail flow rule.   If the connector had previously been saved in a failed validation state. Open the connector and at the bottom of the pane click [Validate this connector]. Repeat the validation process as described above.
