Remove the deep link function by double click on the message. It is so annoying. If I forget and double click on the message, I get the deep link popup window which takes a century to open.

Some of my letters become invisible after sending the mail.

The delete button is right in the middle of the message preview where I want to click to view message, and then it suddenly shows up and I accidently delete the message. I think it should be moved to the far left of the message, out of the way.

It would be able to have a secondary manager option in the Outlook details, which shows as a dotted-line on the org chart. It would make things a lot easier for these AGILE and Consultant organisations

Annoying forwarding notification (Email is being forwarded to ...) every time I open the office web-app. Ofcourse I know that the email is being forwarded. There should be a way to disable the notification.

AIP labels don't show until after the user clicks Encrypt then Change Permissions. This is a clunky experience for the end user and hides a nice feature.

On the Office365 Webmail service, when names have middle name, initials don't appear correctly, e.g., "Doe, John Smith is appeared as "DS" not "DJ" although "Doe, John" is shown as "DJ".
However, the Outlook App shows initials correctly. Both "Doe, John Smith" and "Doe, John" are shown as "DJ".

When I delete an auto complete email address in the new web outlook on the web it reappears next time I open the OWA. We should be able to delete an old or incorrect email address from the auto complete file or process

In the day view, the appointments display in alphabetical order, but they're in seemingly no order when printed.

I like the my day view in the mail tab, but every time I go to a different tab, like calendar or contacts and go back to mail I have to open my day again.

Wrong name associated with a particular contact's email address. I tried deleting contacts, and re-entering them correctly; however, the same incorrect association keeps being inserted automatically in my email messages - very frustrating

Why is there no way to contact MS about problems with Outlook?

With the old Outlook Experience, you could ensure that any items added to a shared calendar by another person you were sent an email notification. The actual setting was "When someone updates an event or task on this calendar, send details of the change to:"

This seems to not be available with the new Outlook experience, or hidden somewhere that is not easy to find.

Could you please add this back in, as it is most useful for Shared Calendars, and available with other email/calendar services such as Google.

I tried dark mode and wanted to start a new mail. My signature is displayed as a white block. I can select the text which makes it readable but it uses a white background?

I lobe that you released Outlook as a Progressive Web App. Look forward to seeing the rest of the online Office suite becoming PWA's as well. Great work Microsoft.

In my calendar I'd like to start a new day at 3:00 AM in stead of 00:00 AM. This because my evening activities show up in the next day if they pass 00:00 h. Would be nice if I can change these times manually to later in the night.

Selected calendars will toggle off when Chrome is relaunched and sometimes when the calendar page is refreshed. Calendar view defaults back to just the individual user calendar.

I dont want to see any adds with spiders or other insects please!! Now i cant use my outlook anymore because of the add.

Currently there is no function to confirm that the scheduled item has been deleted.
現在、予定アイテムを削除したことが確認できる機能がない。
It is inconvenient because it is not possible to confirm what schedule item was registered before.
以前どのような予定アイテムを登録していたか確認ができないため、不便である。
Therefore, I want a function such as strikethrough so that I can confirm that the scheduled item has been deleted.
そのため、予定アイテムを削除したことが確認できるよう取り消し線などの機能がほしい。

when replying all by meeting in an email, and selecting Teams on the calendar invite, the Teams conference info is not included. Can't use this feature and a client called wondering where the conference info was even though I selected the Teams button in the calendar invite.
