Crossover Office will run Lotus Notes R5. If you look on their supported apps page (
http://www.codeweavers.com/products/office/supported_applications.php) you'll see that M$ Office 2000 has a "Gold Medal" while Notes R5 only has a Silver. What does Silver mean?
"The silver is awarded to applications that install, and run well enough to be usable. However, in our testing, we find that these applications have signifcant bugs that prevent them from running flawlessly.
The most important aspect of a silver application is that CodeWeavers makes a firm commitment to bring all silver applications to the gold level in future releases of CrossOver, and that CodeWeavers will respond to and address all bugs reported in these applications."
According to their message board Notes R6 is a high priority item for them (although I think Photoshop is a bigger one right now) and hopefully they'll have it at the Gold Level real soon.
I tried R5 with Crossover Office and found quite a few bugs that would be 'show stoppers' for most users.
And I don't really think that it should be required to run yet ANOTHER product just to get Notes to work on Linux. There should be a native Linux client.
How are you going to troubleshoot problems with Notes? Is the problem with the client itself? Crossover? or is it a Linux problem. Too many layers cause too many problems.
What I find frustrating also is if you look at the "Lotus Domino 6 for Linux" Redbook (
http://publib-b.boulder.ibm.com/redbooks.nsf/RedbookAbstracts/sg246835.html?Open) on chapter 6 it talks about "Installing the Lotus Notes client on Linux". Now why in the world does IBM leave this in the Redbook when it doesn't work on R6??
