e.g. user+test@example.com. This feature is already built in Gmail, see: https://gmail.googleblog.com/2008/03/2-hidden-ways-to-get-more-from-your.html

Do you want me to keep you signed in?
When I tell you not show the message again, stop showing the message. It's a work computer that is shared, I'll never want to stay signed in.

When I indent a bulleted list, it correctly moves from 1. to a. to b., etc. However, when I outdent, the bullet moves to 3. instead of 2.

When hovering over a flagged mail, the flag becomes a recycle bin :(

Referring to the article at https://www.ekaru.com/blog/sent-items-folder-in-outlook-only-shows-my-name, how is the same thing done on Outlook for Office 365?

For Outlook / Office 365 - add a new Reading Pane setting option called "Auto". On initial load, or Window resize, Outlook checks the browser's aspect ratio. If it's portrait (height > width) the Reading Pane will be shown on the bottom; otherwise, it will be shown on the right.

This will help with rendering on mobile devices when they are rotated; it will also help desktop users who have monitors with different rotations.

I have imported a second copy of the same email using IMAP via Thunderbird, and both of them contain Date: Sat, 1 Oct 2016 00:19:05 +0200 (CEST) under "View message details" (when using online web interface) (The language of localization is Slovak), and their source code is also totally exact when compared via Thunderbird, yet the web message viewing front-end differs, as the old correct message says Sat 2016-10-01 0:19, and the new copy says Sat 2016-10-01 1:19.

When replying to or forwarding an email, especially when it has opened in the Reading Pane and has attachments, it is difficult to distinguish the Subject field from the body of the reply/forwarding email, which makes it hard to drop the cursor in the right place.

Can MS either add a visible border to the reply format (the blue border around this field would be perfect) or use a light background color in the fields of the reply email (different background colors for different fields of the email would be perfect).

Possibility to select an option so that every meeting you schedule in outlook is a Teams meeting and contains the information to join
This should be available for the user to configure but also for the admin to force for all users in the organization

It is much recommendable to incorporate the function of the whole mails back up like what the Outlook can provide for Export.

Suggest to enable copy of Pin Excel / PDF Files and paste it to e-mail body as attachment. This would save a lots of time from browsing and searching all over again from the folders. Alternatively make the "suggested attachment" the be the path of the frequently used attachment file, that enable the latest updated file to be attached. Currently files shown at the this menu are from previous e-mails that is not updated. It is not reverent as an attchement in the next e-mails.

Pop outs not working when I click "Reply All" on a meeting. Most up to date version of Firefox in use. https://outlook.office365.com/mail/deeplink?version=2019121602.15&popoutv2=1

Tell me how to stop this.

Suggestions:
Before Every Logout from outlook.com send Automatic Notification, Message "Empty Deleted Items Folder - Yes / No" on the screen.

By this feature you will always clean your Trash, Get more organized, your outlook.com will be more Neat & Clean.

If you like the suggestion then plz let me know.

Same suggestion is given to Yahoomail, Gmail & Outlook.com on 25-December-2019.

Let us see who first implements it.

I would like to have an option to stop delivering notification to attendees for the change on a calendar item.

"Your colleagues" is listed on the contact card in Outlook on the Web.
But it cannot be hidden.

Implement settings that can be hidden.

It takes a few hours for changes on calendar items to be updated if the organization sharing or individual sharing was enabled. It’s inconvenient if we have an urgent matter to be registered in the calendar, because it takes time to let users know that.
I would like you to improve the update timing faster.
