We are part of a big company with multiple brands. We would love to create multiple (at least two) Office 365 company themes (these ones: https://support.office.com/en-us/article/Customize-the-Office-365-theme-for-your-organization-8275da91-7a48-4591-94ab-3123a3f79530). In addition to this, we would love to set them based on their domain.

It is interesting to be able to modify the labels on the Office help page ( ?) in the main navigation.
As this navigation bar is located on almost every Office 365 service (SharePoint, Outlook...) it would be convenient if each administrator of the tenant could control and customize the information that is relevant or not.
It will therefore be easy to find information that you want to push to the majority of the tenant's users.
- To be able to move the labels,
- Be able to add links easily

The new dark mode theme is great, but it overrides the customized colors defined in the organization theme settings. It would be great if we could define an organization-specific theme color for users who choose dark mode.

The themes are too few and too minimalist, please add more themes. Suggestion: Space theme. It would make the experience alot more personal

Before the latest Office 365, users were able to pin often-used apps to the nav bar. It was described in this link:

https://support.office.com/en-us/article/Pin-apps-to-the-navigation-bar-in-Office-365-d536512c-b0f7-49fd-b8db-a8a967e23f23

That feature was nixed. It would be great to have it back.

Restore Pin to Navigation bar in Outlook Web access. In previous layout, it was possible to Pin the Calendar and Mail to the top bar. That feature is no longer available.

Ability to add additional functionality to the Suite Bar. The two primary features would be adding menu items for the user photo menu and integrating custom Help with the Question Mark. Adding Help that actually integrates with the built-in help system available on the question Mark icon.

An admin would like to be able to pin tiles on the Navigation Bar for all users.
* It is not application launcher.

<Background>
A user's company will start using Office 365.
Admin would like to customize "SharePoint", "Outlook", and "OneDrive" titles on the Navigation Bar for initial setting.

*English follows Japanese

■Title(件名)：
ナビゲーション バー のサービス名ロゴの編集を可能にしたい
Enable editing of the service name logo in the navigation bar

■Description(内容):
ナビゲーション バーの [OneDrive] や [Outlook] などのサービス名が既定で入り、変更不可である為、カスタマイズ可能にしたい
Since it is currently not featured, I would like to have the service name logo on [OneDrive] and [Outlook] in navigation bar be automatically filled by default and be customizable.

I get used to the current look and feel of outlook. Then I get an update that changes that look and feel. I see no added value to the changes and I have to relearn where buttons/menus/icons are and what they represent. So, Just stop it please. I am sorry if it might cause some devs to lose their jobs but please stop or allow an opt out.

We need more themes for outlook...
Especially for the kids with school accounts who cough desperately need new themes. Like books, beaches, sports, beaches, animals, magic, magical animals... things like that.

I would like you to implement the following features:
・ to create customized themes and set them as per users or groups theme.
・ to turn on high contrast mode or customize the color contrast on a theme for users who have a color vision deficiency.

For the company logo in the Office 365 theme, 200 x 30 pixels and 10 KB is just too small. If you company logo has any text in it, it looks terrible. It'd be nice to be able to position to the left or even replace the Office 365 logo with it.

O365 Pro Plus is not suitable for a corporate environment. O365 Pro Plus seems to be optimized for tablets and touch screen devices. These are not used in the office setting and even less in call centers etc. The looks, feel and function of this format is clunky and cartoonish. Please add a classic mode so that we in the corporate environment can revert to a more user friendly mode.

When I look at my Sent Items folder in archive, I only see my name instead of the name of the person I have sent the message to.

There is good language support in some of the Office 365 suite such as SharePoint. But the Office.com interface and other features this doesn't have the same options.

For example Welsh, is only shown partially on some of the Office 365 interfaces.

With the new Apps Dashboard, this option does not seem to have any sense now and this article seems outdated: https://support.office.com/en-US/article/Customize-the-navigation-bar-in-SharePoint-Online-D5E8DC9A-73F8-45E4-93B4-8E55B546A5AF

Recent updates keep resetting quick access toolbar and ribbons user customization. The Office suite offers ribbons and quick access configuration Export and Imports. The importing function already validates the settings to insure we don't import discontinued settings no longer available after the updates.

Would be nice if Microsoft was automatically backing up our user configuration and restore what is still good after the updates instead wiping it all without warnings. Got burned few times before I started to export-import manually on a regular base to prevent having to redo it all manually each time MS decides to wipe them.
