Our Exchange Administrator instaled Exchange 2007 SP1 with a secure SSL connection.
Ever since the install and migration from Exchange 2003 to 2007 the following warning occurs for our Macintosh Client when trying to connect to the mail server.
'Unable to establish a secure connection to [servername] because the correct root certificate is not installed.'
Users will have to click ok to accept and then their mail appears.
Windows users using a non-Internet Exlporer browser will receive this message when trying to access their mail via the webmail client
'Unable to verify the identify of *.companyname.com as a trusted site.'
Looking into ideas/suggestions as to eliminate these problems. With Exchange 2003 we didn't have the need to install root certificates to Mac workstations or Firefox users to examine and accept certificates so we think the problem is on the server side.
