Still, it would be nice if you report this to Vandyke. If you do, please cc me.

Changing WinSCP to SFTP version 3 and removing the colon (:) from after "Mailbox" did the trick.

When I log onto that site with SFTP version 5 and browse from root, there's a colon after "Mailbox". When I log onto the site with version 3, there's no colon. Very strange!

So solution is:
WinSCP: set SFTP version 3
Remote directory: /Mailbox/FOOORPTS/INBOX

Thanks for the pointers.

It could be related. Have you tried setting the SFTP version to 3? Also try to seek help from Vandyke support.

I get an invalid handle error when initial SFTP remote directory is /Mailbox:/FOOORPTS/INBOX

I can navigate to the directory manually after login just fine.

WinSCP version 4.3.2 (Build 1201). I got the error in prior versions as well.
