Encrypting problem

S

SHiSo

Hi all,

i got a little prob with encrypting e-mail via certificates. I've got 2 pcs
(Server Ent. 2003), an enterprise CA on the first one (which is also DC,
AD..) and Exchange Server 2003 on the second. 2 users had their own
certificate, configured in Outlook 2003.

First, digitally signed emails are exchanged between them. After each adds
the user to his contact list and his certificate. After it's normally
possible to send an encrypted message. But unfortunately, it only works out
in one way : user1 <---- user2 and not in the other way: user1 ---> user2.
I've got an error popup:

Microsoft Outlook had problems encrypting this message because the following
recipients had missing or invalid certificates, or conflicting or unsupported
encryption capabilities (...)

So i screwed up during the process for user1 ... Because when i use another
user (user3) with user1, it works perfectly, in both ways ...
I think it might be a conflict, i can see user2 certificate in certmgr.msc ..

Have you got any idea to solve that problem ?

Thx a lot ..
