Create Additional Calendars in Outlook

My wife is a heavy Outlook user.  One of the problems I have is that we have a busy and complicate personal schedule around the kids.   Who is doing what changes a lot.  I also have a busy work schedule.  Sometimes those personal "kid's dentist appointment" items clutter up my work calendar.   Sometimes that makes it hard for my co-workers to evaluate my availability on my calendar.   Microsoft Outlook has a solution.  I can create an extra personal calendar for all those personal items and keep them off my main work calendar.  Microsoft Outlook then has the ability to show the personal and work calendars side by side or overlay the two to show a combined view.   Here is there article on how to set up additional calendars:  https://tiny.cc/q5dzf
