we have the following problem. Using a GroupWise (18.1) together with a X.509 certificate under windows 7 does not work.
The certificate can be included and used for signing emails, but after 1 day (few hours) the client is reporting errors. No e-mails can be saved or send.
The only way to solve the problem is to remove the certificate, reinstall it and then send or save the e-mail.

There is no other error message. Using the same certificate with an administrator account seem's to work for a longer period.

Using Thunderbird or outlook with the certificate has never shown this kind of error ...

Any idea ?
