APPLIES TO


 * Microsoft Mail Connection Gateway 3.2

This article was previously published under Q91648



SYMPTOMS
The following error can occur when version 1.0 of the Microsoft Mail Connection imports names from Microsoft Mail for AppleTalk Networks into the postoffice for Microsoft Mail for PC Networks

Error 900: (line X) Alias already exists.

where the X in (line X) is a line number corresponding to an AppleTalk name in the import stream.



CAUSE
There are three possible causes (see the RESOLUTION section below for corrections):

 Two names in the AppleTalk Mail directory are not unique within the first 30 characters. PC Mail limits alias names to a maximum of 30 characters, so the first 30 characters must be unique. Otherwise, PC Mail generates the error to prevent a duplicate alias. PC Mail generates the error regardless of whether you use automatic or manual propagation.

For example, the following names in the MSIMPORT.IMP file sent across the gateway cause PC Mail to generate two Error 900 messages:

A Network Manager@MSMail Server #04455

A Network Manager@MSMail Server #09876

A Network Manager@MSMail Server #9656867

 Version 1.0 of the Microsoft Mail Connection may sort the AppleTalk user list incorrectly prior to exporting changes to the PC Network. As a result, the Microsoft Mail Connection may export names that it exported previously. Because the names already exist, PC Mail generates the Error 900 message. If you add one or more AppleTalk names to the Postoffice Address List (POL) using the -A option for IMPORT.EXE and an alias identical to that name already exists in the POL, PC Mail reports the Error 900 message. It does this for any type of alias supported by Mail for PC Networks and its gateways.



RESOLUTION
The following resolutions correspond with the causes listed above:


 * 1) Make all AppleTalk names unique within the first 30 characters before you export them.
 * 2) Incorrect sorting: Update the gateway to version 1.0b.
 * 3) Alias conflict: Choose an appropriate solution from these three:


 * 1) * Exclude one of the names from the POL.
 * 2) * Rename the UserID or ServerID on the Macintosh to make it unique.
 * 3) * Change the alias for the name already in the POL.

For more information about MSIMPORT.EXE and automatic name propagation, refer to the appendix of the &quot;Microsoft Mail Connection&quot; manual.
