Many folks reply all to a mass email, providing feedback like "Great Job" or "Look forward to this" to hundreds of employees instead of the responsible party. There should be a warning that asks you if you are sure to send this email to 13,000 people at once? This would be a fail safe for when people hit reply all instead of reply.

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.

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.

Always show the full email address of a sender in the view pane. This is a major security risk that the email address of a sender is hidden and requires several clicks to view. Default should always be to show the full sender email address.

I hate that the new unread email count for any box is aligned to the right. I cannot find anything online on how to fix this. PLEASE change this back or at least give the user the ability to determine if they want the count number next to the folder name or aligned differently.

stop stealing screen real estate for the thing I want to use it for: the contents of my email.

It'd be great to reduce the new size of the "from", "to" and "CC/BCC" columns in both the Popped Out New Email window and the inset 'reply' window. There's a lot of "dead-air" above the line where one writes the email

Please add the email SNOOZE option to Outlook for Windows--to match the SNOOZE feature that already exists in OWA/O365.

This is an incredibly handy feature that I use daily in Gmail when I need to follow-up later. Snooze is much easier than adding a follow-up reminder to the message.

Thank you

to have the option to set the option to display/highlight email from specific people in your email box to a different colour - so that they can be clearly identified at a glance

Set the option to keep all meeting invites in inbox regardless of the action taken; even if declined.

Provide a pop-up reminder for users who create a meeting invite with WebEx as the location but do not have a WebEx meeting attached when they attempt to send the meeting invite (similar to the pop-up reminder for users who have 'attach' in the message but no file attached)

When I'm writing an email, I would like to be able to type an email from my contacts into the "to" bar and have outlook autocomplete the email without me having to go to the contacts menu.

The online version of office 365 allows you to set a rule/setting that will allow you to undo a send for up to 10 seconds after hitting send. Please give that feature to the full version of Outlook.

Ability to Print all attachments at once from an email

Hi,While replaying to mail, kindly add option replay with attachment which is very useful to business communication. presently we have to select attachment and paste in new correspondence.

Sometimes you need to rename attachments and the only way is to sabe it to PC and then attach again.

Reduce padding (or add option to configure) in message list to fit more messages.

The setting could be a similar like Word has to switch between Touch/Mouse mode, but would be better if it had manual control how many pixels a user wants. This could be under View Settings > Advanced View Settings > Other Settings, for example.

Allow a sort option in the "Deleted Items" folder to sort by the date/time the item was deleted, rather than the original send date. This would allow easy location of recently-deleted items.

Add "Thank You" and "You're Welcome" buttons in an email, so that when a recipient clicks on the buttons, the original sender gets a brief pop-up text message saying "Thank You", rather than getting yet another email in the inbox that just says "Thank You". And if the email has multiple recipients, then the "Thank You" pop-up text is only sent back to the original sender. This will reduce the volume of useless "Thank You" emails that end up cluttering our inboxes.
