Integration of Apple CryptoToken Kit to be able to use SMIME/PKI functionality for Mail En- / decryption.

Changing 365 accounts? how can we transfer our saved Autocorrects from one account to the other?

Stop using ESC button to switch app from full screen mode to window mode . It's irritating!

Add a function to allow buttons to be added to the ribbon

Please make it more prominent, when Outlook isn’t connected to the server. The status bar on the bottom right of Outlook for Mac is not that noticeable.

It would be great to have a more clear signal when Outlook is offline.

Why can't we have Visio for Mac, as we do for PCs? In fact, why can't we have exactly the same software functionality for a Mac as we do for PCs in general? But my main ask is for Visio!

Please and the Feature to Outlook for Mac (This Functions are working in Outlook APP Windows)

While scheduling assistant allows you to select "Show Work Hours" when Work Days are made in Outlook preferences, it would be great to reflect the work days as well when using Scheduling assistant. For eg. If M-F are set as my work days, I should only see those days in scheduling assistant and not Saturday and Sunday;

Be able to export and import of local and server rules for outlook. There is a general import export which could be enhanced to allow this. It would be very helpful for profile clean-up This way one could separate the good stuff, then drop the junk and import the good stuff again in a refreshed profile.

In older (possibly non-Mac) versions of Outlook I was able to view my calendar on the right side of the Outlook window, while I was also reviewing my email.

We work with a number of clients and have several Office365 accounts. When I am no longer active on a client, the Office365 account for that client gets disabled. Outlook then pops up the update password panel each time I open Outlook. It looks like the only option I have is to delete the account, but I need to keep the emails for reference and retention purposes. It would be great if there was an account preference to set the Account to Inactive so that Outlook no longer attempts to update anything (email and calendar) on the Account.

The new icons are very very very ugly. That pure white over light gray is unappealing and they are all so similar that I need a few seconds of thinking and reading what they are before I can press them.

PS: How sneaky is it that I have to agree to be bombarded with stuff to submit my feedback?

So many useful features (recalling message, importing holidays) are not available in latest Outlook for Mac, it's disappointing! Basically MS is sending a message for NOT to use Outlook in Mac (particularly for corporate users)

The "Report an issue" option has disappeared from my Outlook Help menu. It's been gone for some time now, but I used to rely on it quite a bit when I found issues in the fast release builds. My Outlook client is not managed and the feature is not disabled in prefs.
