It 'just works'.
I've got Office 365 for Business for my personal email. Comes with OneDrive for Business (built on SharePoint) with 1TB storage, all the Office apps, Bing Chat(GPT) for Enterprise, Outlook app on Android/iOS etc. etc. Integrates perfectly on Windows.
The email service is great, works as expected and emails don't go undelivered with great spam filtering.
Can't think of a better provider. I used to be with Google Workspace but after transferring my Google account it's irreversible and can't go back to a 'personal' account while losing access to many Google services like (I know it's dead now) Stadia. Had to create a new 'personal' Google account and transfer everything over manually after doing a takeout - lost a few things like my old YouTube account and Google Play purchases.
