Unlicensed Product issue in MS Outlook 2016, 2019, MS Office 365 : Fix

Encountering the “Unlicensed Product” red flag in the Outlook ribbon right at the beginning of the day is the most circumventing experience for a user of MS Office. As MS Outlook isn’t activated on your system, almost none of the features work, ultimately draining out all the productivity stamina from the user. So, we have discussed how to fix this Office activation issue in small, simple steps.

Fix 1 – Reset the activation timer on Office

There is a timer for Office activation (if you are using Office 365 subscription, it also has an expiry method), which you have to reset.

Step 1 – Before you go any further, quit all the Office apps you are currently using.

Step 2 – After this, open the File Explorer. Using the Win+E keys at once.

Step 3 – Tap “This PC” on the left pane. After this, go to the “Local Disk (C:)” option to go there.

Step 4 – Find the “Microsoft Office” folder and open that up.


office dc min


Step 5 – In that MS Office folder, type “ospprearm.exe” in the search box to find that.

Step 6 – Right-tap this tool and tap “Run as administrator”.


osp run as admin min


Within a few seconds, you shall notice about the activation timer on you screen.

After this, just restart your system. All the Office apps will show up with just their name in the ribbon, nothing else.


Fix 2 – Delete the corrupted license data

If rearming the volume license key doesn’t work, you should remove the corrupted license data and reactivate the Office products.


You have to uninstall the current product key using the terminal.

Step 1 – To do this, first, type “cmd” after tapping the search box once.

Step 2 – Finally, you have to right-click the “Command Prompt” in there and hit the “Run as administrator” button.


cmd run as admin min 1


Step 3 – Now, input these two lines one after the other in the terminal and hit the Enter key to run the vbs script and learn about the current activation status of the Office products.

cd C:\Program Files (x86)\Microsoft office\office16
cscript ospp.vbs /dstatus


dstatus min


Now, here you can see the expiry date of the activation key, along with its last 5 characters.

Note down the “Last 5 characters of installed product key:” in the terminal.

Step 4 – After this, paste this command, and modify it using the last 5 characters of the products key. Finally, hit the Enter button to uninstall the product key*.

C:\Program Files (x86)\Microsoft office\office16>cscript ospp.vbs /unpkey:"input the key here"



Replace the “input the key here” in the code with the actual last 5 digits of the activation key installed on your system.

Example – The code should look like this –

C:\Program Files (x86)\Microsoft office\office16>cscript ospp.vbs /unpkey:WFG99



unpkey 2nd code min


A prompt should show almost immediately stating the “Uninstalled product key successfully.” message in the terminal.

Close everything.

*NOTE – If the code doesn’t work, break it up like Step 3. Use the cd command to reach the location and then execute the script file code.



Uninstalling the key from the device isn’t enough. So, delete the registry associated with the key.

Warning – You will have to manipulate the system registry in this process. So, make sure to create a registry backup.

Step 1 – To do this, hit the Win key once and type “registry“.

Step 2 – Next, tap “Registry Editor“.
