Its seem like a bug to me

Possibility to copy paste recurring appointments in a calendar to avoid having everything to re-enter

Almost every time I close a calendar appointment, Outlook asks if I want to save my changes. There were no changes made to the appointment. How about Outlook doesn't ask to save changes when there were NO CHANGES made by the end user. This has been going on for YEARS. Please fix it.

Allow printing of e-mails from Android smart phones.

Feature to enable to jump to an email folder from a search. When you search for email and find it, enable the folder to be opened from the search result, or provide simple way to go direct to the folder.

Enable Bold, Italics in Subject Line/Location on Calendar

Outlook allows you set a default font and choose your own font for your signature, but no matter what you do, there will always be at least 1 blank line below your signature (in new messages and replies) where the font reverts back to Calibri. This means if you remove your signature, then start typing, you are not in your default font and must manually change it.

I can't imagine there are many people or businesses that still use Telex or Pagers. However, increasingly these days many people have Business and Personal mobile phones. Would it make sense to add these categories to the Phone numbers field in Outlook?

It would be great nice if I could upload attachments to Teams' channel folder. Currently, only folder I can upload is root folder of document library but it is not root folder of Teams. I have to do several more steps to save appropriate folder.

Provide a feature of smart compose or suggested reply in Microsoft Outlook 2016 similar to the lines in Gmail etc.

Like new messages and replies, have the option to include a signature to meeting invitations automatically.

Microsoft should make it easy to convert/create a task to an appointment to make it easy to schedule a time period on a calendar for task implementation.

It will be nice to look through your tasks and then schedule your day based on those tasks and have them nicely shown on your calendar.

Not enough space in the screen to work. Many spaces on the screen use for presentation that reduce the space to work

On the calendar, in the Daily View, Work Week View, and Week View there is a blue horizontal line to indicate the current time. In the two weekly views, I'd like to suggest that the line be darker in the middle when the line crosses the current day of the week. This would help emphasize the current day of the week and make finding 'now' much easier.

Ability to see who deleted an email in a shared mailbox.

It would be great to have an option to open the folder where the message is stored.
So you open a message and within this message you can click on "see in folder" like on MS File explorer.

This would be particularly useful for search result lists...

The ribbon tool bar is too large and taking up too much of my screen. Also the icons on the ribbon bar are too large. The colour range does not have enough choice. The older ribbon bar was much better on office 2010 and has gone south in my opinion. I hate the new ribbon bar and the feel of the system. The system is not an improvement over office 2010

Provide an option or feature to color code different email accounts in Microsoft Outlook 2016. In WIndows Live, we use to be able to color code the different email accounts we had on the desktop version. I want the same ability for the outlook desktop version.

The order of Rules can be changed ONLY by tapping or clicking an UP or DOWN arrow on a SINGLE rule. This is clunky when managing a large number of rules. Develop a method for selecting multiple rules and re-ordering by dragging the selection.
