At the moment calendar and task-list just can be used in separate screens. It would be very useful to implement both features (calendar & task-list) in the main screen of outlook, where mail view and folder structure is located. Windows-version of outlook already delivers this function by a so called "popup"-function, so please make it possible for mac-users, too. thanks.

Microsoft removed the feature for you to select which Category to show on a Calendar i.e. Grid View. You used to be able to do this by clicking on the Triangle next to a Calendar in the Sidebar which would display all of your Categories. Then you could pick and choose which Categories to display on your Calendar. Now that this feature is removed, you must use Filters, which would be OK but Filters only support List View. Feature removed in 16.19 or 16.20 update.

When scheduling a meeting, the colors that are assigned to a meeting, via a Category, aren't being displayed when the Scheduling tab is active

Every time there is a change in agenda, or a meeting shortened to 30 minutes instead of 45, the calendar sends the changes to everyone as an email. If things need to be updated frequently, the people in the meeting get a barrage of emails which is confusing and unnecessary. Please allow the option of sending notifications or not for each change made to an invite. It would be much easier if some changes were able to be made without notifications.

Need to be able to update meeting details such as the description or adding a new participant without emailing all the participants every time.

Let's say I've been invited to a meeting. I want to be able to keep track of questions I have, ideas to bring up, agenda items to propose, etc. just so I won't forget them. Items should be visible only to me.

If you have several calendars from several mailboxes, it should be possible to select the calendars to which you want to get reminders. Right now you'll get reminders from all calendars. Alternatively only show reminders from the main calendar like in Outlook for Windows

I'd like to import a csv file into my Outlook calendar and have it creating appointments from it (same functionality as available for Outlook PC).

Enable the ability to customize (add/remove/reorder) ribbon items.

Ensure the calendar on Outlook for Mac updates automatically when I send a meeting response. Terrible looking at my calendar and then not seeing meetings I have already responded to. This seems to be a new bug.

I just found out that IMAP calendars will no longer sync with Outlook 2016. Calendars are such an important part of business services, I'm not sure why this was removed!

I work from home once a week, so I created an appointment for my remote day and selected "Working Elsewhere" for "Show As". However, in Scheduling Assistant, I am the only one who sees this status, so when someone is looking to schedule a meeting, I appear "Free". Please fix this issue so that Scheduling Assistant shows Busy, Tentative, Free, AND Working Elsewhere status. Thanks.

Provide a small icon view for the ribbon. Access to ribbon is useful, however the current ribbon takes more screen real estate.

Our company uses Gmail. Most users use webmail which I find difficult to manage and difficult to follow threads/conversations. I would prefer to use Outlook. I am a consummate folder user. If I'm trying to get away from Gmail webmail, why make me go back to webmail to create and organize folders? Also, would appreciate the ability to access the corporate address book. This is for Outlook 365 on a Mac.

Really need to be able to configure default views for every app and app section.

Create a new meeting based on the attendees and notes of a current meeting. This could be used to setup a follow-up or continued discussion for that initial meeting. Include in the details of the new meeting the original meeting date/time as a reference.

I have a large number of appointments in my calendar that recur. It seems that only an auto reminder e-mail of detailing the full series is available as opposed to individual reminders on individual days of the series.
Individual reminders would be a great help.

In the previous version of Outlook for Mac, the user could drag an existing event from one calendar and drop it into another calendar, like a shared calendar, simply by dragging it over to the right-side menu and hovering over the calendar the user wanted to move it to.

In the latest version, that doesn't seem to be possible anymore (16.20).
