This article describes how to use the Microsoft Exchange Server InterOrg Replicator utility to share free and busy and public folder information. The InterOrg Replicator utility consists of two programs, the Microsoft Exchange Server Replication Configuration utility (Exscfg.exe), and the Microsoft Exchange Server Replication Service (Exssrv.exe). Using these programs, you can coordinate meetings, appointments, and contact information between members of two different Exchange Server organizations. Additionally, message types can automatically be converted to posts and added to public folders, which can then be replicated.
Using a configuration file created by the Replication Configuration utility, the Replication Service continuously updates information from one server (designated as the publisher) to one or more Exchange Server computers (designated as subscribers). Schedule+ free and busy information is replicated from publisher to subscriber only. For this reason, you must have two free and busy sessions to bi-directionally update free and busy information. Public folders can be replicated from publisher to subscriber or bi-directionally. You can configure the replication frequency as well as message and folder replication logging, and how much processing power you want devoted to the replication process.
There are a number of steps you can take if you encounter problems with the InterOrg Replicator tool.
Enable logging on the Public Folders or Free/Busy Session Configuration tabs.
Check the Ex00yymmdd.log and Ex01yymmdd.log log files for any errors.
Use the application Event Viewer to make sure there are no errors. Configure the Event Viewer with a 2-MB size, and configure it to wrap as needed.
Verify that you have granted the appropriate permissions to root folders and the ExchsyncSecurity Folder. If not, you will receive the following error message.
Event ID 116 Source Exchsync Type Error Category None
Mailbox user (username) does not have enough security to replicate to server [servername] on session 'Session Name'.
WARNING: Create subfolder access is not available to '[SERVERNAME]\Foldername, skipping. WARNING: Write access is not available to '[SERVERNAME]\ Foldername, skipping. WARNING: Write access is not available to '[SERVERNAME]\ Foldername \ Foldername,skipping. WARNING: Read access is not available to '[SERVERNAME]\ Foldername, skipping. WARNING: Read access is not available to '[SERVERNAME]\ Foldername \ Foldername, skipping.
Verify that for each mailbox on the publisher server that you want to replicate free and busy information to, a corresponding custom recipient exists on the subscriber server. If none exists, create one. The SMTP address of the mailbox is the unique key that is used to match mailboxes to custom recipients. If a corresponding custom recipient does not exist, no free and busy information will be published.
If no free and busy information is displayed after you verify that the custom recipients do exist, quit, and restart your client. This forces your free and busy information to be written to the server. The next replication cycle will then publish your free and busy information.
