share a calendar

[meyersroman]

If you have access to or share a calendar with another Outlook user, is it
possible to enter an appointment on both calendars simultaneously

Dear meyersroman,

the short answer is no. You could try to use a synchronization program to
sync both folders.

A list of sync tools:

Maybe it helps.
