hi,
custom toolbar icons(buttons) apply only to the pc being customized as does
all customizations. It does not apply to files or other PCs.
you can customize someone else PC with a macro but doing so without the
other persons knowlege or permission is considered impolite(you may be
altering their cumtomizations) and many consider this action as a virus.
you can copy you icon(button) and distribute it to your users but this is a
hassel for all parties.
A worksheet command button is about your only workable alternative. It is an
object assigned to the sheet and will travel with the file.
sorry.

Is it possible to customize a button in a toolbar (the button will start a
macro in the the workbook), and make it available to end users when they open
the spreadsheet? I created the button on my PC, but when I emailed an end
user the spreadsheet he did not see the button...

If it is not possible through the toolbar, is a worksheet button the only
other alternative?

Thank you for any help.
