Connect your Microsoft 365 mailbox to automatically verify payload delivery status, collect EML data and verify attachment and link integrity.

Prerequisites

  • A Microsoft 365 email account for testing
  • Permissions to authorize OAuth applications
  • The email address validated in delivr.to

Setup Steps

1. Navigate to Settings

Go to Integrations in your settings.

2. Find Your Validated Email

In the Mailbox Integrations section, locate the validated email address you want to integrate with Microsoft 365.

3. Sign In with Microsoft

Click Sign in with Microsoft.

4. Authenticate

Enter your Microsoft 365 credentials. If you have an existing session, verify you’re signed into the correct account.

5. Approve Permissions

Review the permissions delivr.to requires:

Permission Purpose

Read mail in all mailbox folders Check Inbox, Junk, and other folders

Note: Access is limited to the specific mailbox you authorize. delivr.to cannot access any other accounts in your tenant nor make any changes to email contents.
