It is very disappointing that a very common daily use feature as using an adressbook/contacts in outlook is not supported by Microsoft. Please add this feature!

Turn focused inbox off by default. This threw a lot of people off when it was automatically turned on. Easy to turn off but non-technical users are not going to find that solution.

Please add integration for Time Machine Backups. Having the ability to restore mails by just clicking on Time Machine would be a major win. Standard Apple Mail provides the ability to navigate through the mails and restore lost or deleted mails within program window, but unfortunately Outlook does not have this feature at the moment.

I manage a huge number of accounts (gmail, personal domains, hotmail) and all time that have necessary to migrate to a new computer, all account configuration reset. In export menu, must be have a option "account configuration".

Outlook for Mac is not able to send out email as (or on-behalf) a Distribution Group, and always got error message with meaningless error code. However, Outlook for Windows is able to use a Distribution Group as the "From" to send out email long long time ago. This is a very important function for a team who facing users, for example Customer-Support Team or Operation Team.

Display multiple timezones on the calendar view, this feature is supported for Outlook for Windows and I really miss it. Having teams split between GMT and PST its a really handy way to schedule joint sessions.

Since the update to Version 15.38 (170801) - unicode charters in subject lines are not displayed correctly when the initial email is received. Its fine if the email is forwarded on and then replied to - but any emojis using unicode e.g. =?utf-8?Q?=F0=9F=8C=89?= is not displayed correctly

reinstate the ability for a rule to be included in send/receive

As a Vim user I have a habit of tapping Esc twice even when unnecessary. However, on Outlook for Mac this takes the app out of full-screen. No other Mac application I know does this, and it's rather distracting to have Outlook suddenly exit full-screen, so I'd like to see it removed.

Incoming mail can often contain formatting that has ludicrously small or large font choices made by the sender. I need a way to view the content of the messages without styling by default.

See above Change the ability to change the view for contacts so that you can see them as a business card.

Have just bought Office 2016 to run on my new Mac and frustrated that you cannot synchronise the Contacts or the Calendar with my gsuite like I can on a Microsoft computer. Can you help please

Outlook seems to scan all folders, possibly calendars, before attempting to retrieve new emails. (Alternatively, email delivery and retrieval appears glacial when compared to other clients, making it feel like Outlook isn't very responsive)
