Using classic Outlook for Windows in business environments
Not surprising... Microsoft has a collab with Samsung to pre-install MS apps on Samsung phones or at least a variant of Samsung phones. Microsoft and Google are in head-on competition, so Microsoft takes every chance to stab Google. In Chrome browser, if if I switch Bing to search, it will only nag me once. However, if I switch to Google for search or web apps in Edge, it will constantly nag me and import my Google Chrome data without consent. Microsoft is the new evil in tech.
I am very sure it's not the mail app or calendar app, it's the EAS protocol access stack.
