I have just installed RC1 of desktop, however, I have been having this problem for at least the last 2 Desktop Releases.
We are running Version 5.0.8_GA_2462.RHEL5_64.NETWORK Jul 9, 2008 on the server.
So, I have Desktop installed, I can run it, however presently I can only see mail from last August and prior - when I last successfully used it. The status on my account name when I hover over it is as follows:
'Status: Invalid or untrusted server SSL certificate. Please go to edit screen of Account Setup to revalidate settings'.
Yep, that makes sense. So next I click on Account Setup or Setup depending on the skin I"m using (and I've tried several just in case it was a skin issue).
And then I get a lovely 500 error page beginning as follows:
HTTP ERROR: 500
Thus, I can't edit my account settings and sort out the certificate issue.
All help very much appreciated! Let me know if I need to provide more details on any of this. (I have searched the forum, but can't seem to find anyone else having this issue).
