Comrades, I've written tens of thousands of email messages over the past 20 years for work. Outlook is part of the requirement in this process, though I also use other services. After over 20 years, I'm done with it because of two things "copilot" and "editor." I even took MS's advice and downgraded to the "classic" form of MS-365 (NOT to be confused with MS-13 or MI6) to be rid of copilot. Nevertheless, these infuriating "features" remained unchanged, nagging me with every word I typed. Not only that, but "editor" would flag American spellings as misspelled, which is fine, as I usually use British spellings, but then would flag British spellings as incorrect style! Not THAT's helpful, eh?
Anyway, I figured out a workaround that works for me. I've had a Yahoo! Mail free account since 1998! I simply synched the Outlook account to the YM account. Now all of my Outlook sends and receives go to the YM queue with all of the garbage removed, but sends still retain the Outlook address. A word about YM: I've had this account that long. It's been great. The only time it was not great is when they punished us for using an advert blocker to get rid of the right-hand sidebar ad. It forced us back into a primitive 1990's version of the interface. We complained bitterly. Instantly, that restriction was removed. I don't mind getting a few email line ads in with my regular mail. By the way, YM's spam blocking is extremely good. Even with my account being in over 30 historic breaches (including YM's biggest ever), and almost 30 years of exposure, I still get very little spam in my main box. It very neatly collecting in the spam box, for my amusement apparently, and the filters of regular spammers are easily customizable. The maxim is that for every violation of our trust and privacy there is a work-around waiting to be used to squash it!
