Updated: 6-August-2019

Purpose

Using Exchange server you can mark external messages using a transport rule. The common way to do it is to prepend a Subject line or a message text with a phrase like "[EXTERNAL]".This method has at least 2 disadvantages:

TagExternal does not change the subject line and body to mark a message but assigns a special category to a message. You can define this category (a text string) yourself.

About this demo version.

TagExternal demo version prepends "[TagExternal DEMO]" to the tag you defined to mark external messages.

F.A.Q.

Q. I am having trouble getting the program to work. When I enable the transport agent, I get 1052 and 16023 errors in Event Viewer and the Transport service will not stay running.
A. Make sure that you have placed the software files to C:\Program Files\IvaSoft\TagExternal folder. Also note that Exchange server uses the Network Service account for the Transport Service credentials and it seems this account didn't get security permissions to TagExternal folder. Try to add Network Service account read permissions to that folder.
