XADM: MTA Converts (a) to (040)a(041) in Message Tracking

ID: Q249349

The information in this article applies to:

Microsoft Exchange Server, version 5.5 SP3

SYMPTOMS

If you send a message to an Outlook contact or personal Address Book entry that contains an encapsulated RFC-822 address, for example:

C=us;a= ;p=microsoft;o=msft;s=user;DDA:RFC-822=user(a)domain.com

you may find that the message tracking logs in the Microsoft Exchange Server Administrator program incorrectly show the (a) translated to (040)a(041). As a result, the above address appears as follows:

C=us;a= ;p=microsoft;o=msft;s=user;DDA:RFC-822=user(040)a(041)domain.com

CAUSE

The Exchange Server message transfer agent (MTA) is incorrectly translating the parentheses (), which are then written to the tracking log.
