On the Windows version, a blue bar on the left in the message list shows the (un)read status of the email. With one click there, you can toggle between the states. There should also be a one-click toggle on the Mac version of the email list.

Right now there is only a shortcut to toggle through all open Outlook windows (command + ~), but I often want to toggle just between several open mails, say to copy something from one mail and paste it into another, without going to Outlook-Window and click on the mail I am looking for.

Please add an option to set the maximum size for attachments like in the Windows version of Outlook (Registry value MaximumAttachmentSize). This would be helpful to handle internal large messages and to adopt mail size to corporate constraints.

A lot of emails (especially automated emails from internal systems) are sent as "plain text".

Right now these are displayed in tiny Times New Roman, which makes them hard to read, especially data that uses the monospaced nature of "plain text" for formatting, like lining up columns of data.

Outlook for Mac should allow the user to select the font and size to be used when reading (as well as replying to!) plain text emails.

When hovering over a truncated subject in the message list, I would like to see the full subject displayed in hover text. This should probably be generalized to all the fields in the message list, but the Subject field is the one that's most often an issue for me.

Document differences between clutter and junk, and algorithm behind 'focused' view.

I am very surprised that Outlook got rid of the AutoBCC option. CRM's (for example, Salesforce) have an AutoBCC feature so that you can log incoming and outgoing emails directly to a salesforce account. Without this, it is difficult to track what you are doing between email and CRMs.

Since the delete icon is the only icon that is always used, please move it to the outside of the icon list, I often use the delete to move through messages clearing out junk. It is wasteful to keep having to chase down the trashcan icon.

I want to be able to close the preview pane when I'm done reading a message, so that I just see the list of emails (e.g., in my inbox). If my email list is short, I can click on the white space between the end of the list and the beginning of the reading pane, which returns me to my list with no preview, but that's trickier when the list is longer than one screen length.

Please give users the option of turning Junk folder off or on in All Accounts.

This "feature" was introduced without prior notification or consent in an update and it is not possible to configure if you do not want them to appear. Now email is much more difficult to read, and there is no option to remove the distracting gridlines. I cannot understand why the Mac versions of office do not have the same option/features as the Windows versions. In Windows you can turn this grid off quite easily, on the Mac version of Outlook, sorry, you are stuck with annoying gridlines.

The latest update to the Outlook client (15.32) on mac adds horizontal grid lines to the message list (preview pane turned off), but added no discernible option to turn them off. The visual clutter really slows me down and I'm surprised MS would make such a significant, draconian (and completely arbitrary) change to the interface without giving users the option to revert it. Was this even user-tested on customers who had Outlook already configured without the grid lines? Please surface an option to turn them off ASAP.

remove gridlines that came in update 10.12.4. i do not mind if it is an option but you have cluttered up my inbox to where it is unreadable now.

Sometimes when working I don't want to be interupted everytime a new message comes in-I need to hold off on receiving mail, though I need to stay online to plan, review calendars, older emails etc (so Work Offline" isn't an option). Push is great when you want to be in constant contact, but it doesn't help you focus. I would like to have a Mail Snooze button that would let me choose to not receive new email for 15/30/1hr/8hr etc. Let me work uninterrupted.

Please make it possible to view the ruler in an email message.

Replies to emails should not display separately. It takes up way too much space in my inbox. The email thread should just show as a new email when someone replies but on the same line.... if that makes sense.

Allow CMD+C to copy sender address without a need to open a contact

Since the Mac Outlook 15.17 version was released, the Check Names button is no longer available with IMAP/LDAP Directory Service email accounts. Every subsequent update through the current 15.22.0 (160506) has the same problem. This Check Names button is grayed-out and unavailable for name resolution against an LDAP DS. The keyboard command Ctrl+Cmd+C also does not work. Check Names appears to only be available with Exchange accounts now.

This issue has not been resolved from versions 15.17 through 15.33 (170315) and affects all my business clients on Mac.
