Current Apple Mail (Catalina) is rudimentary and shows considerable lack of love from the Company, but Outlook certainly beats it as far as making it consumer unfriendly - locking down the Ribbon and Quick Launch bar, while embedding features within these I don't want / will never need.
I keep returning to Outlook for Mac to see if someone cares at Microsoft, but apparently not. For this, I subscribe and pay a yearly fee?
Maybe I'll just stop kidding myself and delete the product entirely...
To not to be able to customize the Ribbon or Quick Bar in Outlook 365 is counter-productive. Features I do not use often enough are stuck there, while any Add-Ons I might consider I simply won't do - simply adds to the clutter.
Goodness knows the Ribbon in other Office apps is a cluttered mess too, but at least I can put items in the Quick Bar and - for the most part - Hide the Ribbon. No such luck here.
May consider going back to Mac Mail / Contacts / Calendar instead.
Having used other other Office software, I get the Ribbon is, unfortunately, locked - but to then deny access to customize Quick Bar is user-unfriendly. Not intuitive and a, frankly, bad idea by some there.
And reviewing this and other Forums, its certainly been noticed.
Especially, perhaps, in the Personal version of 365 - where not all the bells and whistles of Outlook (for business) are not immediately required - the ability to Hide the Ribbon, but have user-customized quick links to often-used tasks would be welcome.
As it is, it's distracting bloatware. And tied to subscription access, not really desirable. Just sayin'.
