CAUSE
This issue may occur when there is information in the Exchconn.ini file that is not correct.



RESOLUTION
To work around this issue, correct the information in the Exchconn.ini file. To do this, follow these steps.  Start a text editor, such as Notepad, and then open the Exchconn.ini file.

The Exchconn.ini file is located in the following folder, where  is the hard disk drive that Exchange Server 5.5 is installed on:



Important Before you make any changes to the Exchconn.ini file, make a copy of the file for backup purposes. The information in the CONTROL section of the Exchconn.ini file must appear as follows:

[CONTROL]

title = Microsoft Exchange Connectivity Controller (Command-Line)

rootdir = :\Exchsrvr\Connect\Exchconn

If the information is not similar, replace it with this text. The information in the LME section of the Exchconn.ini file must appear as follows, where  is your organization name,   is the name of your Exchange site, and   is the name of your Exchange server:

[LME]

ORG=

SITE=

SERVER=

If the information is not similar, replace it with this text. Verify that the LME-NOTES section has the correct Lotus Notes foreign domain information. Save the Exchconn.ini file, and then quit Notepad. Click Start, click Run, type regedit, and then click OK.
