Fix the function that includes the FROM, DATE, TO, SUBJECT of the original message. Only the date is included, which somehow messes up the grouping by conversation... Outlook will no longer group the emails that are sent without the information of the original message by conversation.

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!

Create Add Project (similar to a task) that users can create/add tasks to.... either "User defined" tasks or "emails" flagged as tasks.
I suspect there are a lot of users who would pay for this addition.
Collaboration feature would be great. Like combining MS Teams with Outlook

add user defined fields for flagged emails

A meeting notification contains a "Join Online" button when the meeting has either a Skype or Teams meeting linked to the item. Clicking on this button currently opens the browser. Clicking on this button should instead start the meeting in the appropriate app (Skype or Teams). Like it does on Windows.

When I get an email from an international colleague, I have to manually translate using a translation service. In Word and Excel there are translate features built right in to the desktop applications. Could an translation feature be baked into the Outlook client? It would be important for business adoption to not log all the contents of mail messages being translated.

Please enable the ability for users to disable the recent addresses function in Outlook for MAC 2016. Users receive automated emails with a noreply address from a user within a tool and since it's in the list of recently used addresses for that user it's selected by mistake and they get a bounce-back message. The list also becomes unusable over time.

My default fonts for mail set in Preferences revert back to Calibri after every auto update. Is this a bug or standard? Can we find a way to stop this annoying behaviour. Thanks

I have a large email collection arranged in a complex hierarchy of folders, both on the server and on my computer. I would find it very useful to tell where each message is stored when I look at the result of a search on all available email folders. Sometimes I am just looking to see if some messages are lost in the wrong folder...

Needing to keep track of the time I work in each task, it would be very useful to have a timer.

Sometimes we need to quote from one email to send to someone else. Give me an option to copy or paste as a quote so the quote indent and attribution follow the text, rather than trying to either make that manually, or to create a reply then copy that into a new message (eg when trying to collect separate quotes from separate responses into one message).

When a meeting is updated with a time or room change either a) highlight or b) add context around, whether the time was changed (context: previous time) and/or the room was changed (context: previous room). Problem: when meetings are updated— especially last minute updates or recurring meetings—it is easy for people to miss exactly what changed and cause confusion.

Contact Groups previously created on OWA and Outlook (PC) should be able to migrate to Outlook for Mac.

We use a 3rd party spelling checker from Druide Informatique called Antidote for Outlook for Mac. Since moving to macOS 10.14 Mojave, the checker is broken. It still works with other applications such as Word, but not Outlook. Our information suggests that Apple introduced security features in macOS that are to blame. We see two options: (a) Microsoft “signs” the Antidote connector for Outlook or (b) Microsoft publishes a new API to be consumed by 3rd parties such as Druide Informatique. Will Microsoft consider either of these options?
