How to fix Outlook Import/Export button Grayed-out issue

Sometimes you will see the Import/Export button is grayed out as shown in the image below

To resolve this issue, I kindly request you to follow the below instructions

Method 1: 

Open Command Prompt as admin right

 

Change the directory to C:\Program Files\Microsoft Office\Office16 

Your directory may be different, make sure that OSPPREARM file is in the Office16 folder as shown in the image below

Type the following command

• cscript ospp.vbs /dstatus
• cscript ospp.vbs /unpkey:LAST_FIVE_PRODUCT_KEY_CHARACTERS

Now restart your computer and see.

Method 2:

Go to Control Panel\Programs\Programs and Features and verify the language used by Microsoft Office in my case it's en-us 

 

Again Go to Control Panel and click change date, time, or number format

Click on the Administrative Tab

Make sure that the Current language for non-Unicode programs is the same.  

In my case it's EN-US => English (United State)
