I have problem with reading mail ( using xp_readmail). I use ASE 12.0 on
WinNT 4.00.1381, and I think I configured XP_Server and Outlook properly. I
can send mail using xp_sendmail and it works. But when I want to read
e-mails, there are errors:

No message retrieved and/or deleted because none found.
Sybmail encountered CMC Error:
The specified message reference is invalid or no longer valid (for
example, it has been deleted)..

But I can see my unread messages in Microsoft Outlook.
Could someone help me ?
