Editing Microsoft Office 365 (section)

===Forced Diagnostic Data Transmission===
Versions other than the Enterprise or Education volume licensing editions do not allow turning telemetry off fully. Moreover, the setting is configured to the least private setting by default.

Office transmits data about 23 000 to 25 000 different types of events<ref>https://www.privacycompany.eu/blog/impact-assessment-shows-privacy-risks-microsoft-office-proplus-enterprise</ref> (other reports in context of the German BSI audit speak of 30 000 types of events) to Microsoft. Microsoft can adjust the level of detail transmitted remotely. This can go up to every single keystroke being broadcast live to Microsoft servers in the background. 

Given that it is not uncommon in some countries even for hospital to run consumer versions of the software, the privacy implications are tremendous. It cannot reasonably be assumed that any data entered into nor any interaction with a Microsoft Office application will stay private.
