When selecting Rules and Alerts from the home page of Outlook, you will receive this error.
This can actually be caused by a number of issues, such as:
- Corrupt rules
- Broken search folders
- Corrupt Outlook profile
To fix this issue, try the following (in order of less destructive)
- Run Outlook.exe /cleanrules from the command line. This will remove all rules from Outlook and Exchange.
- Delete all search folders and create a default search folder with Unread mail as the default
- Re-create the Outlook profile. This is a last resort, but in most cases will work. This indicates something wrong with the local configuration of the Outlook profile
