Convert export calendar to Outlook to late binding




I have adapted code by Helen Feddema to export calendar items to outlook
using early binding. It works perfectly but the database is multi-user & not
all users have Outlook - Novell Groupwise is used instead by these users.

So the problems are as follows:
1. Users without Outlook installed do not have the Outlook Reference library
file msoutl.olb so they get an error at start up. Will this be fixed if I
just copy this file to their computers along with the database front-end
....or do I need to register this on this machine also?

2. If the above suggestions won't work, how can I convert the code to use
late binding - the main part of the code is listed below - apologies fir its

3. Does anyone know how to export the data into a Groupwise calendar for
users who use that instead of Outlook? There are various Groupwise reference
library files available in Access but I don't know where to start...
