Outlook to use procedures written in Excel VBA

[Tony29]

I've tried the Outlook VBA forum for this but no luck. I have VBA code in
Outlook, Access and Excel which have calls to procedures
which are in fact common across all of these applications. I can put the
common procedures into an .xla so that they are available to .xls workbooks,
but how do I put them into a single repository so that they are avaiable to
any application? At the moment I have copied those common procedures from
the .xla to the applications which also require them thus creating a
maintenance problem.

Thanks in advance
