The number of organizations integrating third-party and line-of-business apps with Teams tripled in the two months to late April 2020.

True: Microsoft's reported data (e.g. the FY20 Q3 earnings call or Teams blog) show that the number of organisations integrating third-party/LOB apps with Teams roughly tripled (about 2.7–3.3x) over the roughly two months to late April 2020. Mostly true: there was a large increase close to tripling (about 2.5–3.5x), or over a slightly different period. Mixed: the increase was substantial but well short of tripling, or the metric was different (e.g. apps rather than organisations). Mostly false: the increase was modest, or the metric was substantially different. False: the data contradict the claim.

   “3X increase in Teams app integrations in 2 months”

8. E8 Nadella: Microsoft Teams Users Nearly Doubled Since Start of Pandemic -- Redmond Channel Partner Redmond Channel Partner (Scott Bekker's blog) · 28 April 2021

   “The number of organizations with more than 1,000 users integrating their third-party and LOB apps with Teams has increased nearly 3X year over year,”

The only sources for the tripling figure are the FY20 Q3 earnings call transcript itself (E1, E5) and press reports that repeat Nadella's statement without separate data (E2, E6). The other press coverage (E3, E4) does not address the metric. A later Microsoft keynote slide (E7) says there was a '3X increase in Teams app integrations in 2 months'. It is also Microsoft's own statement, and it counts app integrations rather than organisations. No independent source or underlying published data checks the figure, so the evidence does not settle the claim.
