This is fixed in build 16.0.6568.2036. To get the update manually, go to File > Office Account > Update Options > Update Now.
The February 2016 update for Outlook 2016 is causing problems for POP3 users. Build 16.0.6568.2025 is causing problems for people who have Outlook set to leave mail on the server for a period of time. Instead of deleting the aged mail from the server, it deletes all of the mail. Ouch.
Until this problem is fixed, users should uncheck the option to delete mail after a period of days, while leaving the "leave on server' setting checked. This will leave all email on the server. To do this, go to File, Account Settings, double click on the POP account then click More Settings. The leave on server setting is on the Advanced tab.
The second issue with this update is that POP3 mail left on the server keeps downloading, over and over. Although I'm not sure exactly why it's downloading the mail multiple times, the usual fix when this happens is to not leave mail in the Inbox on the server. That won’t help someone who wants to leave mail on the server.
Switching to IMAP will solve this problem, but you might want to revert to an older version and wait for the next update.
Revert to an Older Build
First, go to File, Office Account, Update Options and Disable updates then create an appointment on your calendar to re-enable updates in early April.
To revert to the February 9 2016 build 16.0.6366.2068, open a command prompt as Administrator and type or paste this command line in the Command Prompt window:
"C:\Program Files\Common Files\microsoft shared\ClickToRun\officec2rclient.exe" /update user updatetoversion=16.0.6366.2068

Following the recent update I cannot now edit the subject heading of Inbox or Sent messages even though the Edit box is selected in the Actions heading
Is the header collapsed? If the open message is using the newish collapsed header, it's not editable - there is a V in the lower right of the header area to expand it. Screenshots: http://www.outlook-tips.net/tips/edit-subject-outlook-email-messages/
They have released an update build that fixes it - build 16.0.6568.2036. To get the update manually, go to File > Office Account > Update Options > Update Now.
Thanks so much for valuable article which solved my problem.
I am having a similar problem with a brand new Surface Pro 4 where I am being told "The system cannot find the path specified" - I've tried both the cut & paste and manually typing it in.
I have multiple pop email accounts but it is only occurring with 2 of them.
I found it to work when I changed the directory to the root c:\ directory in the command window, then highlighted the command line, right clicked to copy then right click to paste in the command window. Pressed enter and the downloading process began.
There was something wrong with the command line - extra spaces were getting added after the \ when pasted. it *should* be ok now, if not, type it or copy it from this text file - http://www.slipstick.com/doit/officec2rclient-revert.txt
Thank you. This worked and was simple.
