Provide an ability to customize the ribbon, like moving features around. I wanted to move the SEND button farther to the right but can't.

Reorganize your ribbon so that functions are grouped together, OR better yet, allow users to customize their ribbons and quick access toolbars for their own needs as users on a Windows platform can!

Allow ability to see Calendar (or tasks, etc.) on right sidebar while working in mail. This was previously very helpful in past Windows versions

If you want to export Zimbra to PST then you can try any professional software like KDEtools Zimbra to Outlook Converter. This software easily import Zimbra file to PST and numerous file formats such as EML, EMLX, HTML, PDF, NSF, OLM, and etc. The tool retains metadata of email during the conversion process. The tool is compatible with all the latest and oldest versions of Windows. The tool also supports Office 365 and Exchange Server account.

The undo feature exists with (ctrl|cmd)-z and in the edit menu, though those locations are pretty hidden. A nice prominent button in the ribbon would be convenient after accidentally deleting mail.

The colorful (blue) one is ugly.

Please add option in settings so I can stop Outlook from requesting confirmation when I am deleting any emails. This is cumbersome also because you require the confirmation with no way to turn it off.

This is needed so sandboxed apps can use script Outlook with AppleScript. According to Apple, it's not a lot of work to implement this:

> For scriptable app developers, implementing support for access groups is relatively trivial, and requires making minor annotations in their app’s scripting definition (sdef) file. - https://developer.apple.com/library/archive/qa/qa1888/index.html#//appleref/doc/uid/DTS40015156-CH1-SANDBOXINGOSXAPPS__INCLUDINGSCRIPTABLEAPPSANDAPPLESCRIPTAPPS-ABOUTAPPLEEVENTSTEMPORARYEXCEPTION_ENTITLEMENTS

Cloud version now has the best usability. The only missing feature is native notifications on meetings. But i love how it filters to show only new content in the email thread. Great job!

I love the idea of the dark mode option, however on most cases I find it hard to read with a dark background due to recent updates. I hopes there's a permanent option to switch to light mode for reading pane, instead of having to push the light switch all the time when scrolling through emails.
Now I gotta turn off the whole dark mode option for reading and efficiency purposes.

In the latest update why have you added having to hold down the control button as well ?

Hello,

I commute between the Slovak Republic and the Czech Republic almost every week. Every time I do so, Outlook shows me an alert:

"The time zone setting for your computer has changed. Would you like to update the time zone setting in Outlook?"

The Slovak Republic and the Czech Republic are in the same Time Zone.

I use fast insider on macOS. My colleague commutes every day and he gets the same alert on the stable track on macOS. This issue has been happening to us at least for half a year already.

The five buttons for Mail, Calendar, People, Tasks, Notes are at the bottom of the page while the rest of the controls are all arranged on the top? Without a touch bar, the mouse is going up and down when working with email and calendar.
It would be fantastic if these controls could be configured to be arranged on the top of the account tree right under the ribbon.

If I view a messages in a Groups mailbox (or a delegated mailbox) in Outlook, the Add-ons are not accessible. This is a real pain and means I have to subscribe to inbox delivery for these Groups when I don't want to. I know add-ons are per account, but maybe there is a way add-on's could be granted access?

Be able to see and insert file types like JPEG, PNG, PDF and other non Microsoft document files located in cloud in either OneDrive or Sharepoint to be able to add it in the “Insert Link” feature when creating or responding to messages.
