Return Receipt when e-mail is sent

No way to view message source without opening email...

The Master checkbox used to only select what was on my screen, this made it easy for me to clear batches of email quickly. Now, the checkbox selects everything in a folder, even if I've not had a chance to see it. This is not helpful at all.

Safe Senders all deleted and cannot save new ones!!

Scroll bars are far too narrow, and making the bar mostly invisible makes it incredibly difficult for people with limited eyesight to see, and the tiny size can make it awkward to select.

I am looking at Office 365 as a viable alternative to Google Apps. One of the most useful features of Google Calendar is that I can have multiple reminders specified. So for instance my default is to receive a reminder 2 weeks ahead, 1 week ahead, 2 days ahead and 2 hours ahead.

I can only see an option for one reminder on the Office 365 calendar and can't see how to add more. This is a serious omission. A basic calendar requirement in my opinion.

Years ago it was possible existing users to create alias with "hotmail.com"- or "outlook.com" -domain. Now it's only possible to create alias with "outlook.com"-domain.

However new users (becoming Microsoft Account users) can choose their first email address between "hotmail.com" or "outlook.com" domains. I think this is unfair!

Please, give existing users ability to create new aliases with "hotmail.com" -domain so users can choose between "outlook.com" or "hotmail.com" -domains.

We would like to print the calendar for any range of dates and list all of the scheduled events date and time etc

It would seem a good idea if the Delete button inthe contacts list actually allowed you to delete contacts that are no longer required.

EMail Deletion

Why can't I delete the emails showing on the panel vs having to delete my entire Inbox?? I don't like having to click each one seperately.

In the old view I can select all, and have it select only the visible messages. With this new beta select all seems to select my entire inbox. I would like both options.

Add the One Note choice back as a location to either save or move to.

Allow us to remove the 'Conversation History' folder. I have no use for this and never will. Please allow us to delete it.

Would like a way to re-arrange folders, current their is no way to organize the folders position, when you drag a folder it only allows it to become a sub folder, but I want to move the positions of the parent folders. such as Inbox, Custom Folder, Achieve, Custom Folder, Deleted, Junk, etc.

In Outlook 2010 and later, users can choose to display the total number of items in each folder (rather than the number of unread items). Please add this feature.

If an e-mail was read only on a single click and deleted, it still shows as Unread in the Deleted Items folder. It makes more sense that it shows as Read?

Not good if you want to view in snap mode or on smaller widths as you've not included a responsive design.
To actually use some features you have to view the website and on smaller devices it makes sense to cater for this.

On outlook 2016 I have set up a quick action where I can create a calendar or task directly from an email, copying all the content of the email to the event/task details. Could this be implemented onto the site ?

As title says, don't show folder two times (in favorites section at the top and below) if it's marked as favorite
