Hello,
I am an independent adviser, and I am trying to help other users in Community with my experience in Microsoft products.
Normally, when printing a calendar in Month view in Outlook, it will automatically select the month containing the currently selected date. But, you may need to print the calendar within a custom date range, such as 3 months, half of year, etc. Please go through these links and the article in it will introduce the solution for you:
