i want to remove the ad sidebar in windows outlook email

You do realize you  just replied to a 4+ year old post about a different version of outlook.com mail right?

If you use either Chrome or Firefox as your browser, there is a free ad-on that will remove the ads and expand your inbox to use the space where the ads were.

Do a search on "webmail ad blocker". That ad-on is free and there are versions for Chrome and Firefox. Download and install either or both versions (depending on which browser you are using). The ads in outlook will no longer be displayed.

You certainly can, just download a copy of adblock (free), and wallah!

looks like the only way to increase page space even after getting rid of the right-side-of-the-page advertisements by using FIREFOX is by upgrading and paying $20 a year which means I will disable mICROSOFT oUTLOOK email before I will pay their extortion money.

microsoft and mcdonalds getting together and putting up adds on outlook email does nothing more than cause me to never again go to mcdonalds. microsoft is turning into a necessary evil  by forcing phone and alternate email from us. I will quit the account before I allow them to extort that information which is none of their business.
