Get your Treo to work with your corporate Excahnge Server

Our IS department didn't support Treo 700p or 755p and I suspected that it had to do with our security certificate.  Versamail 3.5 is more careful about self-signed certificates than previous versions were – and since 3.5 is installed on the 700p and 755 – these devices won't work without installing the self-signed certificate.  It's pretty easy.  What you need:

a) The Palm Certificate Modification Tool

b) The certificate from the company's exchange server.  May need to get this from your IS department.

If you are a company IS person reading this – then you can do most of the work for your users.  If you are one of those users – and the IS folks have done this for you – follow along from step #2.

  1. Using the Palm Certificate Modification tool and the .cer file for your exchange server, create a .pdb file.  Call this certs.pdb.  Follow the directions on Palm's website to do this.  Once you're finished – you can delete the modification tool, since (unless you change the certificate) you won't need the tool or the .cer file anymore.
  2. Have a file called certs.pdb?  Double-click on it to launch the Palm install tool (yes – I'm assuming that you have installed the Palm Desktop software and Hotsync manager installed on your PC.  If you don't you will need to do so now – using the CD-ROM that came with your Treo, or you can download from the website).
