Florian,
I dont agree that this is an uncomon wish !
To be able to recieve signed and encrypted emails in e-mail clients is absolutely needed feature for us !
And for archiving - dont forget that for Enterprise CA, we have all the keys of staff members. OR in MS Certificate Services - someone ( admin by default ) can open all encrypted files and mails of the users.
You dont try to tell me that this bug will not be fixed , do you ?
Because with Outlook connector 10 - i can see signed and encrypted mails without any problems, even against Scalix 11 server. So the problem here is exactly in Outlook connector.
For SWA - to be able to see that the message is signed is no big work to be done ( one icon in front of the message ). For encryption in SWA - i agree that this is huge work, because of certificate handling.
