Outlook Cannot Import Eudora Messages When Eudora Mail Is
Stored in a Non-Default Location
This article was previously published under Q257354
SYMPTOMS
Outlook 2000 does not import Eudora messages when the
Eudora messages are stored in a non-default location.
CAUSE
This behavior occurs because Outlook searches the default
Eudora e-mail installation location for messages in the C:
\Program Files\Eudora folder.
Outlook searches for both the In.mbx and Out.mbx files in
C:\Program Files\Eudora folder. If the files do not exist
in this folder location, Outlook 2000 does not search any
further and reports that zero messages have been imported.
WORKAROUND
Use one of the following two methods to work around this
behavior.
For a small number of workstations, the behavior can be
resolved by manually moving your Eudora messages to the
default Eudora installation point:
C:\Program Files\Eudora
-or-
Use REGEDIT to modify the Eudora registry setting to point
to the non-default location where your Eudora messages are
stored. This setting can be found under HKEY_LOCAL_MACHINE
in the following registry key:
SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Eudora.
exe
Modify the value name "Path" (without quotation marks) to
the name of the directory that contains the Eudora
messages. After this has been done, Outlook 2000 can locate
the Eudora messages when you import.
