How to disable shared mail in Lotus Domino

Technote (FAQ)


Question

An administrator would like to disable shared mail on a Lotus Domino 6 server and restore full copies of shared messages to each recipient's mail file. What are the steps necessary to accomplish this?


NOTE: Domino 8.5 no longer supports the Shared Mail also known as the Single Copy Object Store (SCOS) feature. If a server contains mail files that contain shared mail, or the object store databases exists on a Domino 8.5 server, they will continue to be accessible. However, no new mail messages will be created by release 8.5 or up that are shared in the object store. This includes new mail delivered, and the ability to use the object store link utility to link a mail file's messages into the SCOS.

During server startup, informational warning messages will appear on the server console and logged to the system log with information for the administrator. The information will list the mail files that currently contain mail messages that are shared in the SCOS, and the shared mail object store files that exist on the server. For example:

    10/22/2008 08:31:20 AM   <mailfilename>  is linked to shared mail, please unlink this database from shared mail.  

The goal is to unlink all the mail files that are using shared mail in order to be able to take advantage of the superior disk saving features of Domino 8.5.

Answer

NOTE: Prior to disabling shared mail on a Domino server, it is important that you create a full backup of the shared mail database and the associated user mail files.

1. Verify the number and size of the messages in the shared mail database. Use this information to determine if there is enough available disk space on the server to store complete copies of the shared messages in each recipient's mail file. At the server console, type the following:

Load Object Info -full <mail>
* where <mail> is the name of the directory containing the user mail files.


2. Record and disable the existing Shared Mail configuration

Information of the server(s) should be recorded in order to properly plan and apply the steps outlined in this document.

Record Shared Mail information
Go to the Shared Mail Setting tab in the Server document and record the following information:

2a) Mail file usage of shared mail.

This is obtained by running the following on each mail directory and piping or making a copy of the output results.

object info -full <mail>  


2b) Shared Mail File configuration in the Shared Mail tab in the server document.

This is obtained from the Domino Administrator client. It contains all the information about the directories where the shared mail is contained.

Disable Shared Mail
The Shared Mail tab in the Server's document contains a field called shared mail , this must be set to none. Save the changes and then recycle the server.


3. Unlink all mailfiles from the shared mail database.

Perform a garbage collection on the user mail files:

Load Object collect -force <mail>
*where mail is the directory for user's mail files (to unlink only a specific mail file, run the unlink on that mail file explicitly)

Load Object Unlink <shared_directories>
* where <shared_directories> is the name of the directories for the shared mail databases recorded in 2b above.

Load Object Unlink <mail>
* where mail is the directory for user's mail files (to unlink only a specific mail file run the unlink on that mail file explicitly)


4. To confirm that the shared mail database is empty, issue the following command:

Load Object Info -Full <shared_directories>
where <shared_directories> is the name of the directories for the shared mail databases recorded in 2b above.

and on the user mail files:

Load Object Info -full <mail>
* where <mail> is the name of the directory containing the user mailfiles.


5. Shut down the Domino server and then delete the shared mail database at the operating system level.
