Moving the Directories for Storing Mail Data

You can move the directories that store mail content to another location
on the same or another partition. Use this option when disk space is
insufficient on the current partition to serve larger data volume or
amount of mailboxes and you want to move all mail content to a new,
larger volume.

To move the mail content directories to another location, follow
these steps:

1. Log in to the Plesk-managed server as a user with administrator
   rights by using Remote Desktop.
2. In the Windows Start menu, select All Programs > Plesk >
   Plesk Reconfigurator. The Reconfigurator application window
   opens.
3. Select the Change Plesk Mail Data location option.
4. Specify the destination directory name. If the directory does not
   exist, it will be created.
5. Click Next. During this operation, Plesk’s services will be
   restarted.
