Check the “Current Version” number for Outlook 2016. This can be done in several ways.

You can check Office forums, Google and Technet forums to find it.

Otherwise, you can just go to “File > Account” in any of the Office Software like Word, Excel, PowerPoint etc. You will find the version number and build number over there, as shown in image below.

For example, I’m using the latest version of Outlook 2016. The version number is 1611 and Build Number is 7571.2109.

Then open the Run dialog box, using Win + R.

Type one of the following commands in it, based on whether your Windows 10 is 64 bit or 32 bit.

64-bit version, type:

“%programfiles%Microsoft Office 15ClientX64OfficeClickToRun.exe” /update user updatetoversion=(version)

32-bit version, type:

“%programfiles%Microsoft Office 15ClientX86OfficeClickToRun.exe” /update user updatetoversion=(version)

Here, the version number is the one relevant to you, which you found out earlier.

When there is a prompt, select the option “Repair” Office.

This can also be done using “Programs and Features” in the Control Panel. You can select your version of Office 2016 and right-click and select “Change”. Then select “Repair Office” in the next dialog box.

Solution 2

This type of scenario arises when you have a bad add-in in Outlook. With the intention of different functionality you keep on installing new add-ins from time to time. These all take resources (time) during the startup of Outlook 2016. Sometimes, Outlook opens slowly, but sometimes it crashes. In such cases you can follow this solution.

  1. Select “CTRL” key using your desktop keyboard while opening Outlook 2016.
  2. Select “File” > “Manage Add-Ins“.
  3. Now disable all types of “Add-ins” which are active by default. You can also do it by going through File > Options > Add-ins, if by luck Outlook starts at all.
  4. Restart Outlook again and check to see, if it’s not crashing.

Solution 3

This type of problem arises, when you have a graphics card like NVidia. You probably optimize its settings for better resolution, but the same can be a culprit in causing Outlook crashing. So you just have to toggle with the features of your Graphics card and set to default settings. Probably your Outlook 2016 will be normal again in Windows 10.

  1. Go into Outlook > File > Options > Advanced
  2. Look for “Display”
  3. SELECT/CHECK the “Disable Hardware graphics acceleration” option. (if it’s not already checked)

I’m running SB with the NVIDIA GeForce graphics adaptor and it may be linked to Outlook 2016 not playing nice with the graphics acceleration.

The following are set of common steps to proceed whenever there is a crash with Outlook. You can follow them by order and eliminate that reason is the cause. Then restart Outlook and see if it works normal again.

Step 1:

Start Outlook in safe mode.

Launch Outlook in safe mode by choosing one of the following options.

  • In Windows 10, choose Start, type Outlook.exe /safe, and press Enter.

Step 2:

Is there any Outlook pop-up dialog box open?

Sometimes Outlook 2016 asks for confirmation of an action using a dialog box. For example, when you try to “Clean up Folder” it will show a pop-up message, to check or select some options. If this pop-up goes background, you will not know that it is there. So, check for open dialog boxes, using Alt + Tab.

Step 3: Make sure Outlook isn’t working on a large or long process

If you try to move or delete large number of messages, Outlook may take a long time to complete the action. So, check the status of Outlook operations at the bottom of the screen. If it is doing something, wait till its complete. If the process is complete after a few minutes, Outlook is back to normal again. Also, it is a good practice to do such operations from time to time, instead of doing it once in a year or two.

Step 4: Install the latest Windows and Office updates

Sometimes, a bad glitch in Outlook software or system programs can cause a crash. It is good to update your Windows 10 and Office 2016 whenever new updates are available.

Step 5: Repair your Outlook data files

During the installation of Office, a default repair tool called SCANPST.EXE is also installed on your desktop. You can utilize the service of this tool, to repair any crashes of Outlook by scanning data files and repairing errors.

Step 6: Create a new user profile

The last resort for Outlook not opening for a long time, is to create a new profile. Sometimes the old profile may have some settings which may conflict with other data files of Outlook. So whether it is Windows 10 or 8 or 7, you can start fresh by creating a new account.

Problem with Anti-Virus or Internet Security

There are lot of anti-virus software and Internet Security programs that create lot of registry entries. They also alternate the settings of other programs like Outlook 2016. For example, McAfee, which is a brand anti-virus software can cause crashing errors in Outlook.

To solve this, you just have to disable Host IPS in its settings. This is a typical example and may happen with any other anti-virus program. You just need to do some troubleshooting to find that right setting that is in conflict with Outlook.

Solution 6

Typical Updates

For example, in earlier versions of Outlook crashes sometimes used to happen whenever there is a new update. So, in the same way, if you have a new update for Office 2016, you just need to search Google if this is causing any crash issue to Outlook 2016. If so, then you just uninstall the update and run Outlook again. If you find it runs normal, just prevent that update from running again, till a fix is found.

Solution 7

No Internet Connection and Old Teamviewer Add-on

Sometimes an outdated add-on version like Teamviewer 11.0.53254 which can cause crashes to Outlook 2016 is the primary cause. You may first not able to identify this cause.

But when you find that Outlook is crashing when there is no Internet connection, it could be a similar problem. So always try to update your Outlook add-ons and if it still does not resolve the problem, just disable them.
