Microsoft did not raise M365 prices for more than a decade, thanks to software efficiencies on top of hardware.

Judge as of 2026-06-04. The core test is whether Microsoft went more than ten years without raising list prices for Microsoft 365/Office 365 (the main commercial suites), counted from launch (2011) to the first general price increase. True: official Microsoft pricing announcements show no general list-price increase for more than 10 years, and Microsoft has attributed this to efficiency gains, or credible sources support the attribution. Mostly true: the no-increase period was more than 10 years, but the 'thanks to software efficiencies' attribution is not supported, or is only Microsoft's own characterisation (a secondary detail). Also mostly true if the period was roughly 10 years (say 9.5 to 10 years) rather than 'a decade plus'. Mixed: the period was clearly under ten years (about 7 to 9 years), or a general increase happened in the period but was minor. Mostly false: there were several general list-price increases during that decade, and only some SKUs stayed flat. False: Microsoft raised M365/O365 prices broadly and repeatedly within the first decade.

   “This is the first "substantive pricing update" for Office 365 since it launched ten years ago, according to Microsoft. There have been some small price changes over the years, but Microsoft's phrasing is accurate.”

2. E2 Microsoft 365 and Office 365 prices to increase next year — here's who is affected Windows Central · 19 August 2021

   “Since its initial launch, Office 365 has increased in value while remaining the same price.”

3. E3 Microsoft cuts the prices of some Office 365 plans IDG News Service (via ComputerWoche) · 16 March 2012

   “As we rapidly add customers, the cost to run Office 365 becomes more efficient.”

4. E4 Microsoft cuts the prices of some Office 365 plans IDG News Service (via ComputerWoche) · 16 March 2012

   “Prices for the four plans for midsize businesses and enterprises, labeled E1, E2, E3 and E4, dropped, in that order, from US$10 to $8; from $16 to $14; from $24 to $20; and from $27 to $22.”

Windows Central reported in August 2021 that the coming increase, set for the following year, was the first "substantive pricing update" for Office 365 since its launch ten years earlier. It also said Office 365 had kept the same price since launch, with only small changes along the way (E1, E2). The 2012 changes in E4 were price cuts, not increases, so the evidence shows no substantive price increase for about a decade [E1]. The only support for the efficiency explanation is Microsoft's own 2012 statement that costs fell as it added customers (E3). That describes efficiency from scale, not "software efficiencies on top of hardware", and no independent source confirms the explanation, so the verdict is mostly true rather than true.
