Consider the following scenario in a Microsoft Exchange Server 2013 environment:
- A distribution group (DL) and a mail contact share the same display name.
- The alias of the mail contact is the same as the common display name.
- You set an inbox rule for the DL in your mailbox by selecting the where my name is in the To or Cc box option.
This issue occurs because a lookup ignores the SMTP address and returns the wrong recipient by using QueryFilter filter.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
