Using Classic Outlook on Windows for personal email, calendar, and contact management
Not sure if you’re still looking for the solution on how to Find the cache exchange mode I have an iPhone so I asked Siri how to change that so you may want to Google it and you’ll get the answer. I have a full description in picture to go on the outlook website. Also use the Mail app but you have to go on the Outlook website, but I’ll give you pictures on how to do it. I hope this helps.
