Previous Office updates allow users to be able to select the new meeting location's history, sort of like an autocomplete feature where in users can use the up-and-down keys on their keyboard to select the previously used location for their past meeting when creating a new event in Outlook calendar. Since organization don't user Resource mailbox (Rooms), we relay on the Geolocation search. Now that users are in Office 365 Apps for Business version 2006 - with Windows 10 version 2004 build, this feature is no longer available.

Have the ability to drag an email as a PDF format in personal folders than having to do the printing feature to convert it to a PDF,.

Add 'Acknowledged' and 'Thanks' buttons to emails that will tell the sender you have seen/appreciate their email, without having to send another, thereby reducing email traffic.

Enable back "Always prompt for logon credentials" for Outlook client/email

Since it has been grayed out and not able to change. Users should have that option due to security risks when using office and outlook.

Make it possible to prompt for user credentials every time or not

The spell check works in the subject line and highlights errors but autocorrect does not work - why not enable autocorrect in the subject like it is in the body of an email/calendar invite

Outlook Task not working properly with To Do Integration, Subtask is missing when it is synced to Outlook

Expand search window on click on the search box

Currently Search box is not much of user friendly and its very small window, if the search window is automatically expanded once user clicks on the search box that would be more user friendly and more productivity

In the task bar, latest icons for Outlook 365 and Word 365 are too similar (blue).
It's confusing.

There needs to be a way to automatically change the theme of Office apps based on what the global Windows theme is set to (light or dark). When dark mode is enabled on Windows, it is very unpleasant to have a bright white background on Office apps. Having it synced to the system-wide global setting will eliminate the hassle of switching the Office theme everyday manually.

Sometimes the owner of a meeting (or, more often, meeting series) is on vacation or changes jobs; it would be nice if they could assign ownership of an instance (for vacation) or the full series (for job changes) to someone else. Also provide an option to create a meeting on someone's behalf without being included in the meeting.

Organize Contact list

I love being alerted 15 minutes before a meeting begins and being able to snooze until 5 minutes before it starts.
However, the reminder window stays open even after I join the meeting I was reminded about, and it's a little annoying. If the window could be aware that I've joined the meeting it's reminding me of and close automatically, that would be very helpful.

A button on a Meeting that creates a new meeting with the same participants (and perhaps subject) as the original.

In Microsoft Outlook 2016, when we forward\reply\reply all to the email with attachments, the attachments are not available and we have to attach them manually. An option to reply all to the email with all the attachments included would be more productive in Microsoft Outlook 2016 as that option is not available as of now.
