Considering the last price increase was almost 4 years before this one goes into effect, most of those are pretty modest 1-4%/year increases. In line with inflation. The notable outliers are F1 and F3 which got a lot more expensive

Apparently F1 and F3 are "Office 365 for Frontline Workers". F3 is kind of like Office 365 Basic, F1 is stripped down to mostly read-only access plus Microsoft Teams
