I like how fast it is at searching my calendar for an appointment or event versus Outlook where you have all day long if there's something in your inbox/calendar not matching up with what someone else has added (or they've changed their mind). It could be faster but we're getting used to this speed after years using Office 365 ProPlus which isn't nearly as quick when editing appointments! This makes our life easier because its easy enough even without any special training from IT staff members who work primarily within Microsoft products so no more having them spend time setting everything back again just minutes later - only then are things working properly now instead waiting until late evening hours before being able access anything important via emails etc.,.
