I have been using outlook mail ever since it was hotmail.com. The whole product has deteriorated in last 5 years. UI has been clunky and non user friendly. They wanted to monetize email and ended up adding all these integrations with third party ads further downgrading the UI performance. Either the product team behind outlook web mail has no clue what a good UI product should like or the company overall does not care of outlook anymore. For us, we are stuck with this clunky email service which was once an epitome of good user experience.
