Microsoft exchange

[Jim]

When I was using windows98 I was able to open the address
book for my Corel WordPerfect Office7 using Microsoft
Exchange EXE 4.0 .
Now that I have upgrade to WindowsEP, Microsoft Exchange
EXE 4.0 does not work.
I have tried the compatability utility, but still cannot
get Microsoft Exchange EXE 4.0 to work.
Any suggestions?
