This is one of the must have programs for your PC or Mac. As of this writing the cost is $12.50 per month for Outlook, Word, Excel, PowerPoint, Publisher, (PC only) Access (PC only). You also get 1 TB of storage on OneDrive with a Microsoft 365 subscription. With a subscription everything stays updated automatically; no need for a one time purchase. Well worth the price in my view. Microsoft Office 365 works perfectly on a Mac.
