I perform many roles within my company, and I really wish I could have the ability to switch between multiple e-mail signatures when composing e-mail via the Outlook 365 platform

Adding multiple calendars to Outlook on the web is time-consuming. Therefore, I would like to add "calendar" at once.

<日本語訳>
複数の予定表を Outlook on the web に追加するのは手間がかかります。そのため、複数の "予定表" 一括で追加する機能を要望します。

It would be great if we could control sending a notification of changes which is automatically sent every time when users change the setting of the shared calendar.

I use four different email addresses and I want to be able to distinguish them.
By having From emailaddress visible,
not just To, Copy and Subject.
Now I need to double check which email I´m using.

+
Showing the true sender emailaddress
in my inbox, not just senders nickname and shortening. From my point of view the sender can call him/her self anything between heaven and ..., but by showing the real address I instantly know if its the right or fake person writing the message.

I have my email set to reply as default, never reply all. However, this setting seems to do literally nothing. When I open an email and scroll to the bottom to reply, it still says reply all. The setting seems to only control default reply in the reading pane but I have the reading pane disabled. Why have a setting that doesn't accomplish anything? I just emailed my entire department a private report which you can imagine is mortifying. PLEASE ALLOW ME TO DISABLE REPLY ALL.

Remove suggested files for the attachments. It does not work and takes up room.

Since I always sign "Kate," why does the system keep trying to prompt me to use "Kathleen?" It's an annoying feature, and it seems to me that once I've typed various forms of "thanks, Kate" numerous times, it should prompt me by suggesting that name.

Users who have a reviewer permission of the Outlook calendar can see peoples’ calendar item details such as event title, location, organizer by clicking the event. If any Teams meeting is scheduled, its URL can also be visible to reviewer users, even if they are not invited in the Teams meeting.
So, I would like to hide the URL of Teams meeting from non-attendees.

Why did outlook start "nudging" me to reply to an email? I don't need or want this. In fact, it is kind of irritating. How does this junk get activated without me asking. And I really don't want to take the time to search for the solution to de-activate stupid features like this.

Previously, clicking Inbox while a message was selected would deselect all messages. This is what I want!

Now it selects the first message and instantly marks it read, which is INCREDIBLY stupid! How am I supposed to deselect all messages now??

We have two different resource mailboxes which has similar name and we would like to distinguish these two by icons. In order to make this possible, we are hoping to be able to change icons of resource mailbox.

Every time I try to refresh the Outlook tab with the ⌘R shortcut, I end up making a new reply, but to get rid of this would mean turning off keyboard shortcuts entirely. Please, please, PLEASE change this.

I sent lots of emails and there isn't a button for template or maybe the icon has changed.

The "Let me select which message to read first" option no longer works even after changing the option, saving, reselecting the option, and then saving. The first email opens in Outlook web even when the "Let me select which message to read first" option is selected.

It would be great we could switch the Add online meeting option from Skype Meeting to Teams Meeting after sending the invitation in Ootw calendar.

Although there is a different range of themes, it'd be nicer if there were more as some of them are distracting or too childish.

If I want to share my contacts I should use Outlook clients to do so. But it would be more convenient if I could use Outlook on the web to share my contacts with others.

In the mail outlook view, we can select the calendar sidebar. Please provide a feature to pin the calendar sidebar.
