When opening Outlook and/or opening the Manage Rules and Alerts screen, you receive the error:
There was an error reading the rules from the server. The format of the server rules was not recognized.

- Restart outlook.
- Open Rules again, if you see (client-only) rules again delete them all.
- Create any simple test rule and save it.
- Restart Outlook.
