Mail files are created on the server that is specified in your registration preferences. If the Domino Upgrade Service cannot create a user's mail file for any reason - for example, if the specified mail server lacks sufficient disk space - the user remains unregistered and an error is logged.
Because mail conversion requires mail files to be created immediately, you cannot choose the option on the Mail pane of the Register Person dialog box to create mail files using a background process (adminp). An error message is displayed if you attempt to select this option.
Note The options "Convert mail" and "Convert mail ONLY" are mutually exclusive. An error message appears if you select one of these options and the other is already selected.
