It is possible to add a subject line to a new conversation. I suggest to create a dense view for a channel. Instead of several lines (name&date, subject, 4 lines of content, See more, replies summary), I suggest to have 3 lines: name&date, subject, replies summary. Then have less space between entries. This way, I can easily find relevant conversations in a busy channel to add another message.

I would love to have an easy to use protected (access-controlled) space for sensitive files, Personal Vault would be great for Business OneDrive!

Turn Off Suggested Attachments in OWA O365. This give the end user the option to use it or not. We've had several complaints about this feature being dangerous as a user could inadvertently add a sensitive attachment by accident and send it. Being a Hospital with 30,000 + users you can see how this is a valid concern.

When planning an appointment there are 5 options: Free, Working elsewhere, Tentative, Busy and Out of Office.
Is it possible that you change the option 'Free' into 'Available'??? ‘Free’ is very confusing.

Currently there is a limitation where we cannot use the phone system add-on on Office 365 Business Premium License. This hinders small business using teams as Phone System solution, if they don't want to upgrade to Office 365 E3 or higher.
simply make the add-on available is my suggestion

Simply put: I like dark theme in calendar. I do not like dark theme for reading mails.
Right now the dark theme switches both to dark. I would like separate settings.

Actuellement, les jour disponible sont noir et les jour occupé sont gris pale. Une bulle de couleur autour des dates disponibles serait apprécie.

I would like the default of "end on" to "no end date". I own a house cleaning business. Most of our clients are recurring for years. We started noticing that a random client would disapear from the calendar. I took us a while to notice that MS 365 programed all recurring appts to end at about 6 mo. This default has cost us!

Often discussed question, but as a company it is very important to have a straight, uniform and trustable outside representation, including external user can see the profile photo of outlook 365 users to know, with whom they are communicating.
May you implement this as a function?

set default calendar setting for all new created users

In 365 online, if I accidentally hit the trash can icon instead of the flag or unread or even just selecting the email, there is no undo button - I have to go through my deleted emails to find the one I accidentally deleted.

I'm very disappointed that you no longer have the Military Home Use Program download. We are not looking to spend $70 per year in order to access work files on our home computer. We do not like subscription services. You should offer download options.

Whenever I'm using any of the Office 365 web application and use the app shortcuts to jump to other web apps, the new app opens in the same window.

Ideally, it should open in a new tab.

Microsoft Support Duplicated my Documents in Documents and One Drive and they cannot currently be deleted in 1 step vs. individually. Need Microsoft to develop a fix for this problem.

Like the title says, instead of making people who upgrade their license go through reinstalls, provide an easy method to upgrade the software within the app to save time and admin hassle.

Workflow is not working. Although approval gibven, it hangs
Very poor "development"
Usless

Having considerable difficulty with setting up email Domain with SquareSpace platform. SquareSpace is not among the platform-sites having specific information about setting up the connection with Microsoft. Plus, SquareSpace has two methods available for accomplishing this, but one method involves adding an extra expense for the website. We don't think establishing the connection with Microsoft should necessitate an extra billing opportunity for SquareSpace. Please add SquareSpace to the current list of those website platforms having specific domain settings available for Microsoft users. ; - > thanks

STOP "SAVE FILE AS" WHEN "BLOCK DOWNLOAD" IS SELECTED. Currently when sharing a file, if "Block Download" is selected, the user can still "Save As" which enables the user to download the file albeit with a different name. So Block Download really does not Block Download. Recommend when "Block Download" is selected, option to save on local drive is deactivated to prohibit download.
