Looking for Best Practices

[peter@mxtoolbox.com]

We are a hosted Zimbra provider and I was wanted to ask the community what are some best practices to try to get the best experience for our customers who are going to install the Outlook Connector. I've seen a lot of installs go smoothly, but quite a few where the install crashes, Outlook crashes after the install, ect. If you were going to give somebody instructions on how to go from Outlook connected to either a regular MTA or an Exchange Server, what's going to provide them with the cleanest, most pain free experience? What types of things need to get done after the install to make it feel like it used to?

Right we tell folks to run the Office Update tool to get Outlook up to date, then export their mail to a PST. Upload the PST using that tool, and then install the connector. Is there anything else you can recommend?
