Make it so you can have an option to make the theme go across the entire page instead of just the top, and add custom themes.

I hate the new look and would like to return to Classic

Option to revert to previuos 365 Premum email format.

The new version is very awful to use, wastes space, why does the catagory thing need to have the name on it, columns now acnnot be narrowed.

THIS IS MUCH LESS ACCESSIBLE FOR FOR DISABLED PEOPLE.

How to schedule/delay sending emails onweb not an option - needs to be.

This needs to be fixed as the frustrating delays far outweigh any of the benefits of the new version

Using MS Forms, I would like to embed a simple survey form or questionnaire in email messages, without the recipient having to open another page to access the form.

This means that in the body of the email, the questions would be displayed and placeholders for responding to them.

My organizations SKYPE search is gone. It runs slow. Just plain bad.

Not sure who thought this was an upgrade.

outlook desktop has the ability to attach an email ("outlook item") to a calendar invite. I don't see a way to do this on office365, but would love to have this capacity. It instructs the people on the calendar invite about the email background via attachment.

I prefer classic view of calendar (colored bars for events), as both color-coding and size are easier on my eyes while working extended periods at a time. Not sure why this was removed?

We need to check whether equipment is returned. So, it would be nice to have a feature that can flag for returned equipment or send a mail and/or pop up a notification when the booking expiration date comes.

the new version makes the text flash on and off when I move the mouse. how about give and option to switch back to the old version?

If you register a recurring item in a delegate meeting room, you have only two options to Accept all items or Decline all items in the invitation sent to the delegate.
So, please allow the delegate to decline only one recurring item meeting room has a double-booked events on the same day.

We would like to restrict users from calendar sharing if the users try to do it by themselves.

We would like to alert to a user or perform an action if multiple domains are in the To or CC lines in order to avoid sending a mail by mistake.
We need this functionality for users to use emails in a secure manner.

We would like to view the display name registered on the sender’s client when receiving mails from other clients than Outlook. Currently, the display name is shown as its set in Office 365. It will be more convenient if we could receive mails with sender’s display name showing.

When using the reminder for the first time, a large number of events added by other users would be shown in the reminder. So, it would be great if you could implement a feature that can set the period for each event appearing in the reminder view.

Please please make the Delay Delivery feature available in Office 365 Outlook. That is the best feature and when I'm working at night and want to send emails to staff without making them feel compelled to respond, delay delivery would let me accomplish that.

Thanks,
A

Currently, you cannot change the calendar group list for the user/meeting room calendars after they got added from the Add calendar option in Outlook on the web (you can select the list “when” adding calendars).
Also, the shared calendar cannot be moved from People’s calendar after it is approved.
This behavior is very inconvenient, so we would like you to implement the feature that can change group list for a calendar “after” adding it.

Previously, it was easy to find a meeting room because all meeting rooms or room list distribution groups was shown in the calendar in Outlook on the web. However, the new design is difficult to use because the search doesn’t return results like before by using the search keywords. Also, we have to be familiar with the search keywords to get expected results. So, please revert to the previous behavior.
