Using classic Outlook for Windows in business environments
So you've gone to the trouble in an attempt to gaslight someone who's rightly frustrated with Microsoft's new advertising system, but given advice that is completely useless and ineffective.
Your instructions: Settings/General/Ad Preferences does not apply as a) There is no "Ad Preferences" under General, and b) Ad Preferences do not apply to Microsoft specific advertising (the very reason this post was made in the first place).
If you're going to be needlessly rude and over confident, at least offer a solution while you are doing it.
