Multiple choice of colors and themes like black theme in Desktop Outlook 2016. Also provide an option of feature to reduce too much white space used in Microsoft Outlook. The new outlook is very complicated. Unfortunately I was forced to upgrade to outlook 2016 and Windows 10, otherwise I would have kept the old version of outlook. Microsoft need to consider people feedback and make material changes to outlook in order for users to be able to use it in the most efficient way. Right now, I am finding difficulties in using this outlook. Outlook should be more colorful like the old version so users can distinguish between mailbox, folders, junk, recycle…etc. Users should be able to easily find folders and folders with new version of outlook, just like old version. New version is all white and gray and doesn’t allow users to easily find required options. Also layout should be more efficient and unnecessary options must be removed. It’s important for Microsoft to understand that outlook is used for business purpose and users with high volume of work/tasks will not be able to easily coop with their work using a complicated outlook. Outlook layout look very busy and they are so many options. Bring old version back. It was easier to work and handle emails. Also an option to match color schemes or themes with an organization’s color themes would enhance customization.

Provide an option to allow font size to be changed in Microsoft Outlook 2016 including the font and colors for the folder pane. Also make it possible to customize the fonts for Mail, People, Calendar on module basis. Also, Allow user to make a permanent (default setting) change to the font and size template for mail created in Outlook 2016 under Windows 10, not just on a mail-by-mail basis.

Also, set a default font that is always applied to my tasks. They change depending upon the email moved to tasks.

Also, Please give us a way to make the fonts and lines darker on the email form so that they can be easier to see and use. They are just to light and hard to read.

Outlook 2016 has lost the great UI that Outlook 2010 had. The current colors, fonts, clarity, shapes, icons, etc. are very hard to see and understand. Folders are widely space, screen real estate is squandered, and work productivity is reduced. I realize that many of the changes are to make outlook more compatible with touch screens and mobile apps. However, most Outlook users use it for WORK. We use a keyboard and mouse. We do not use touch screens, but do need Outlook to be easy on the eyes for 8+ hours per day, fast, and easy to use. We manually file emails in folders and keep records that need to be quickly accessed. Perhaps there needs to be two versions - one for keyboard and mouse users that is similar to 2010, and one for touch screen users with all that extra space and washed out icons and colors.

Icons in the Quick Access Toolbar (QAT) are now monochrome in Microsoft Outlook 2016. The custom icons which are colored are very limited in number. It would be nice to get Quick Access Toolbar icons in different colors.

Also, as someone with challenged vision, I find Outlook 2016 more difficult to see. I have had to turn on reading pane in order to zoom my emails so I can read them. But I really don’t like using reading pane. I have found a way to increase the font size in my emails list, which is helpful, but other than that, everything in Outlook looks too small (icons, calendar list, mailbox list, etc). I can find no way to enlarge these things a little bit so that I can look at them without straining my eyes. Please provide an easy way to customize Outlook appearance for people who are visually challenged.

If you turn on AutoPreview in Outlook 2016 and the message list is in its wide mode, each message or conversation has about half a line of empty white space under each message's AutoPreview text.

I use 1-line AutoPreview, so this extra space steals over 10% of the available vertical space in the message list!

To repro:
1) while viewing inbox, turn off preview pane or move it to the bottom
2) maximize outlook so that it will switch to its "wide" mode with sender and subject on the same line
3) turn on auto-preview and set it to 1 line

Expected: message's bottom border is only a few pixels below the bottom of auto-preview text
Actual: half a line of wasted space.

There isn't any wasted space at the top of the message, only underneath it.

It doesn't show up when AutoPreview is turned off-- in that case, the display is very efficient without wasted space.
