It would be great if when you build folders you could make the decision to keep them online or take them off line. I believe this would speed up synchronizing, but they would still be accessible and off the servers.

Please add a field to Outlook Contacts for academic credentials and professional qualifications, e.g. MBA, PhD, CPA.

Once my mailbox gets full I can move messages into archive folders. However, I am still blocked from sending or receiving because Outlook still thinks my inbox is full.
A manual refresh option would be nice

The Focused Inbox is great; We today apply a lot of Email rules and keep our Inbox clean, moving email into folders. Most times there a lot of important emails lying unread in our folders and would love to have more rules to be applied so that :
1. They go into separate folders
2. For specific scenarios, and customizable settings, they would go into the 'Focused' Section of the folder.

The Focus Folder rules would be user provided and not automated like we have for the focused Inbox

I'm sure it was Outlook that used to show a picture icon and name of who was attending the meeting. I don't see it. This is very helpful

We would like to refrain from checking our work e-mails when one is not in office (e.g. on my mobile phone) - and its apparently not good for ones mental health to be always "on" - but at the same time have an idea of whats going on, e.g. if I receive e-mails in the weekend or during a vacation. It would be beneficial if we somehow get Microsoft Outlook 2016 to prepare a summary e-mail over incoming e-mails for a given period and send to private e-mail address? An add-in maybe?

a PSTfile can contain thousands of drafts and sent Email, especially in the purges, filtering them out manually can prove to be a tedious tas, so far I couldn't find a filter or a query that can filter out drafts or Emails that has not been actually sent apart from the actual search items.

It's very annoying to get a yellow warning every time Out of Office is turned on. You set a start and end time knowing when those times are, why warn me every time I open Outlook that it's in effect? Very annoying and unnecessary. Allow me to acknowledge and silence the warning like you can for a calendar reminder or get rid of the warning altogether.

Need the ability to export to Publisher calendar from Outlook 2016

Allow a GPO removing all cloud links when emailing by default. When someone in our Org is emailing an person with no access to our internal on prem sharepoint, they should not get a "edit link" that doesn't work anyway. Allow us to turn this off.

It'd be nice in Skype if it could should show the time zones your contacts are in next to people's names, both so that you aren't bringing someone something complicated at their end of day, and many people leave themselves 'available' all hours with their mobile devices but as a West Coast person I'd prefer not to interrupt East Coast colleagues in the evenings.

Provide the ability to specify which columns are printable for a Category. Alternative: Provide more than one printable phone list - Business, Relatives, Friends, Club #1 Members, etc. - each may have differing printable columns. (Our house uses 3-differing phone lists on our refrigerator.)

Also,offer a “BOLD“ option for listing phone or other entries

Once I select a name from the suggestion drop-down and start typing the next name (in the To or CC fields), the drop-down still maintains the same order as before. It would be nice if the already selected name is moved to the bottom of the list as the possibility of choosing the same name again is very low.

Provide a feature to enable safer deletion of emails in Groups and recovery as well in Microsoft Outlook 2016 plus add a warning to let people know that they are deleting the ENTIRE group, not just one member.

While there are meetings/appointments/etc, it would be nice to have a feature for Events such as team parties and outings outside of the regular hours. Be able to link restaurants and similar abilities.
