Rules were set in Microsoft Exchange 2003 and the mailbox was migrated to a Microsoft Exchange 2007 or later server. The rules are not visible in junk mail or transport rules.
- GFI MailEssentials
- Microsoft Exchange 2007 or later
Microsoft Exchange 2007 and later do not show Messaging Application Programming Interface (MAPI) rules for each mailbox without a specialized tool.
You can edit the rules in one of two ways:
- Set up a 32-bit machine with MS Collaborative Data Objects (CDO) installed and use Rules Manager to remotely connect to your Microsoft Exchange 2007/2010 machine.
- Use the Microsoft Foundation Class (MFC) MAPI editor provided by Microsoft to manually delete the rules. This involves logging into each mailbox where the rules are set.
