If any add-ins are checked, uncheck them.4.

If Outlook starts normally, then that add-in is the culprit.

If it doesnt then you uncheck each other add-ins in different category.

This will rule out the problem with add-ins causing the Outlook 2016 not working inWindows 10.

Sometimes the problem may lie withdevice drivers not working properly in Windows 10.

If any of them are available, then upgrade your OS.

Sometimes Outlook 2016 updates are also installed during this process.

Microsoft sometimes releases these updates to repair any security or not working issues.

Once they are patched up, it may start working again.

Another problem which is less often seen in Outlook 2016 isyou cannot send or receive e-mail.

This was seen in the earlier editions like 2007, 2003 and 2002.

Whenever you face this problem, you backup your existing profile if possible.

Then create a new Outlook profile.

If any profile exists, make it as the default profile.

If that resolves the problem continue.

Otherwise, delete that profile and create a new profile with the default controls.

Another problem is whenOutlook hangs up when you try do a task.

For example you make a run at archive and/or move large number of messages at once.

This causes Outlook 2016 to work behind the scenes.

Sometimes this looks as if Outlook is stuck.

Give it a few minutes to finish the process.

Otherwise, you could browse the file.

Choose Start to begin the scan.

It contains all the information saved on your mail server.

If any problems with this file, dont take a stab at repair it.

Instead delete the offline file and recreate it by downloading all of your items again from online mode.

For example in Office version 1705 (Build 8201.2193 Click-to-Run), Outlook 2016 crashes on startup.

It shows a message that Microsoft Outlook has stopped working.
