The new Outlook update puts a yellow background highlight on flagged messages. It is awful to look at an inbox full of yellow highlights. Please remove this highlighting or allow it to be disabled.

Ability to see who deleted an email in a shared mailbox.

Would like to see more color options for themes like the online version has. The limited options all look kind of bleak and don't give room for a personal touch.

Whenever we cancel a recurring meeting , each time it as "only this meeting " or whole series.

It would be good to have an option where it allows us to select some number of meeting invites.

For Example: If a recurring meeting is sent for 3 weeks. and if user want to cancel the meeting for 1 week , the popup should have option to select from and to dates and to cancel all 5 days meeting invite at once.

It would be great if we could search calendar items in the calendar regardless of how the calendar is added.

It would be good, very good, that if I have several email accounts: Account 1, Account 2, Account 3, etc.

If, for example, in Account 1, I add an email address to "Blocked Senders", Outlook also gives me the option of adding that email address to the "Blocked Senders" in the others accounts.

The same for the "Safe Post."

Add option to email all invited attendees even if you didn't organize the meeting.

Makesit hard to know which Folder you are in.

Since moving the search box to the title bat, you removed the title. Word, Excel, and Powerpoint are fine.

I opened Outlook acct & icons on ribbon changed. Offer option to use old icons/ opt-in or out choice when making such changes

add a quick link under the "delay delivery" menu to "send message at 8 AM the following business day" so that I don't have to configure every email I am sending to my team over the weekend.

Do not change the history of meetings that have already occurred when make changes to a recurring meeting for future dates.

Time stamp on emails, replies, etc should be accompanied by time zone.

Enhanced email search - search multiple criteria (similar to Gmail) Sender, recipient, date, folder, keyword, subject, etc including Wildcard search.

automatically return an email to a blocked sender

Set the option to keep all meeting invites in inbox regardless of the action taken; even if declined.

When typing an email, many times it will fill in the rest of the email address and could be the wrong address due to an error. How can the incorrect email be deleted so it is not readily there to be used?

It's about time to add a dark mode on the Outlook Today Screen. It's a pretty useful feature but it just don't make sense to have a white background on a dark mode setting.

Please provide the unread email count badges on taskbar. It is so useful to know what drops in our mailbox while working on different task in different window. It will save 30 second to 1 minute. You can imagine how powerful feature would be and there is no doubt that a lot of resource hours ( No of current users * 60 Seconds = x number of hours ) can be saved adding this feature.
