Heather_3578not sure if this is the fix but I had the same error on a redirect rule on an inbox. I had set up the rule a year ago and it was working fine until very recently. I followed the instructions on this guide:

The UI is slightlty different as the screenshots in the guide, but you can access the policies screen at the following link:

I haven't tested to see if this is the fix but it's worth a try.

My users set automatic forwarding of there mail messages to another work account. After allowing forwarding for these users in the antispam rule it worked.
