Command Line Syntax

DLManage.exe [Add/Remove/ViewMembers/ClearAll] [Args]

Syntax: DLManage.exe Add [Username] [GroupName]

Remove
Removes a user from the specified distribution list or security group
Syntax: DLManage.exe Remove [Username] [GroupName]

ViewMembers

Multiple group names can be specified for any of the above commands by separating group names with a comma (no space before or after the comma). If any group names contain spaces then the group must be enclosed in speech marks, as shown in the above example.

Log File
Each time DLManage runs it will write to a file named DL-Log.txt in the same directory that the application is being run from (if the file does not already exist it will be created automatically). This file will contain details of any changes made or any errors encountered and should be reviewed after each execution of the program if you were not able to see the on screen output (for example if the app is set to be run on a scheduled task).
