This article explains how to ensure essential emails from Right-Hand don’t end up in your spam, junk, or Clutter folders in Microsoft 365. By setting up some simple rules in the Exchange Admin Center, you can tell the system to always trust these messages based on a special code (called a "custom header") provided by Right-Hand. Following the steps ensures these emails are delivered directly to inboxes without being filtered out. Just ensure the rules are prioritized so they work correctly and aren’t overridden by other settings.
