Please allow us to change the Sent From email from no-reply@sharepointonline.com to something else. I send emails using WorkFlows and need to have the Sent From address be something I can define from a field in a list or library.

In SfB on premises you have the ability to set "EnablePresencePhotoOptions" to true under New-CsClientPolicyEntry.

This then allows you enable users with the ability to specify a URL for a profile picture in the SfB client.

In SfB online, you're unable to run New-CsClientPolicyEntry, and/or can't enable EnablePresencePhotoOptions.

A a result you cannot specify a publicly accessible image URL for profile pictures and meetings with user external to your Office 365 will be presented with the default blue avatar picture.

Add a setting to the planner application to be able to set the default location attachment files are saved. Currently attachments uploaded are saved in the root folder of the SP site that hosts the plan. If the plan was created thru a Teams Channel the attachments get saved in the root Documents folder of the Team which results in a mess especially across multiple channel plans.

Please add week number on calendar.
Once we click on date at the bottom right, we can see calendar, but to see which week we are in, we need to go to outlook calendar.

In Publisher 2010, one had the option to print using a CMYK colour scheme, which is required by the commercial printer that does the printing of my newsletter. The functionality has worked well for many years. When I upgraded to Office 2013 (on an Office 365 subscription), I see that the feature was removed (i.e. one can only print in RGB format). Why was this feature removed, and can it be reinstated?

Problem syncing document libraries with metadata in columns. A lot of companies are using metadata columns in document libraries for search and other reasons.

When printing from Excel online (in either IE or Chrome) the paper type is defaulting to A4 instead of Letter.

When creating a task, notifications should go only to the owner and assignee by default. You can change it to:

Entire group
Assignee only
Assignee & Owner

Currently when we share files through One Drive and SharePoint, a file URL forms automatically, and we cannot rename the URL.

I suggest that URL forms based on our custom domain instead initial domain, so it looks much more professional to those who we wish to share the files to.

When creating documents on Excel offline, as a British user the standard date format is always set to DD/MM/YYYY. When this is then uploaded to OneDrive and people work on the document online it automatically displays the date as the american MM/DD/YYYY, which causes all sorts of issues, especially with formulas and especially if people are entering dates once the document is online.

Allow creation of playlists in Microsoft stream. This should be able to be controlled by admins to create training series', etc., or by users for custom playlists of their favorite videos.

In a larger organization 300+ users, we find that the autocomplete cache over time gets filled with contacts that are infrequently used yet sometimes staff end of sending internal emails to these contacts that should have been sent to an internal contact instead.

Would like ability to reset/clear the autocomplete cache for OWA or to disable it for certain users or all users.

In Google docs etc, you can add a comment (just like office 365) but you can @mention. We use it a lot for collaboration and we are trying to migrate to Office 365. This missing feature, while not a show stopper, is causing some groups real pain.

Currently, OneDrive for business can be automated to a point where adminstrators can launch OneDrive Setup but the user still has to key in their email address to set it up. This makes it harder to ensure folder redirection for every user works. If we could allow the first time setup to be automated, Orgaisations can ask users to restart their workstation once to confirm folder redirection will take place.

I am a big fan of the Office calendar but currently if a meeting or appointment gets cancelled I end up deleting it from my calendar. I would love it if there was a way to set appointments as cancelled in the "Show As" section but keep it on my calendar with a on/off toggle for my recorders.

Allow tracking of whether the members of your team have viewed a message that you have posted in Teams, similar to Facebook Messenger/WhatsApp.

Actually it is not possible to obtain a free Exchange Server 2019 activation with a hybrid key. For earlier Exchange Versions this works trough HCW, but not with Exchange 2019: "Please note that HCW does not provide a 'hybrid key' for Exchange Server 2019. If you need a hybrid key, the latest version that it is available for is Exchange Server 2016."

This is not customer friendly at all - so please add Exchange 2019 to this feature.
