Office asks for activation every time it starts — solution

If Word, Excel, or Outlook displays an activation message every time you start them, it usually doesn't mean that the licence has suddenly "disappeared". In practice, the program is unable to permanently read or save the activation status. Most often, the problem is related to damaged licence data, incorrect Microsoft 365 account credentials, remnants of an older Office version, or damaged Windows system files.

What does this error mean

In simple terms: Office works, but every time it starts, it doesn't recognise that it was already activated earlier. The program treats the computer as if it required re-confirmation of the licence, logging in, or refreshing the product key.

When does it occur

The problem most often occurs:

• after updating Office or Windows,
• after changing the Microsoft account or password,
• after migrating the computer to a domain or changing the user profile,
• after installing a second version of Office alongside the old one,
• after restoring the system from a backup,
• after deleting registry entries and credentials with "cleaners",
• after a long period without an internet connection in Microsoft 365.

Causes

Known causes of this error include:

• damaged Office activation files,
• incorrectly saved credentials in the Credential Manager,
• conflict between Retail, Volume licence and Microsoft 365 subscription,
• remnants of a previous Office 2016/2019/2021/365 installation,
• damaged Windows system files,
• faulty system licensing service,
• lack of permissions to the user profile or damaged profile,
• problem with online activation, KMS server, or communication with Microsoft service,
• exceeded device activation limit for the Microsoft 365 account,
• incorrect system date and time.

Step-by-Step Solution

Run all commands in the Command Prompt as an administrator.

1. Check Windows System Integrity

First, repair system files, as a damaged Windows often causes recurring activation issues:

DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow

After completion, restart your computer.

2. Check Windows Activation Status

If Windows activation is damaged, Office may also behave incorrectly:

cscript %windir%\system32\slmgr.vbs /dlv
cscript %windir%\system32\slmgr.vbs /xpr

If the system is not activated correctly, try:

cscript %windir%\system32\slmgr.vbs /ato

3. Check Office License Status

For Office 2016, 2019, 2021, and Office LTSC, use ospp.vbs:

cscript "%ProgramFiles%\Microsoft Office\Office16\ospp.vbs" /dstatus

If you have 32-bit Office on 64-bit Windows, use:

cscript "%ProgramFiles(x86)%\Microsoft Office\Office16\ospp.vbs" /dstatus

Check if the result shows LICENSE STATUS: ---LICENSED---, ---NOTIFICATIONS---, or information about the last 5 characters of the key.

4. Remove Old Office Key and Reactivate

If you see an old or incorrect key in dstatus, uninstall it. Replace XXXXX with the last 5 characters of the key shown in the previous step:

cscript "%ProgramFiles%\Microsoft Office\Office16\ospp.vbs" /unpkey:XXXXX
cscript "%ProgramFiles%\Microsoft Office\Office16\ospp.vbs" /act

For 32-bit Office:

cscript "%ProgramFiles(x86)%\Microsoft Office\Office16\ospp.vbs" /unpkey:XXXXX
cscript "%ProgramFiles(x86)%\Microsoft Office\Office16\ospp.vbs" /act

If it's a volume license and you're using a KMS server, you can also check the configuration:

cscript "%ProgramFiles%\Microsoft Office\Office16\ospp.vbs" /dhistorykms
cscript "%ProgramFiles%\Microsoft Office\Office16\ospp.vbs" /remhst
cscript "%ProgramFiles%\Microsoft Office\Office16\ospp.vbs" /act

5. For Microsoft 365, Use the New Activation Mechanism

In newer Microsoft 365, ospp.vbs may not always show the correct license status. In this case, run PowerShell as an administrator and execute:

cd "C:\Program Files\Microsoft Office\Office16"
.\vnextdiag.ps1 -action list

If the license appears to be damaged, remove it with the command with the correct LicenseId:

.\vnextdiag.ps1 -action remove -LicenseId EWW_GUID_ID

Then, restart Word and log in to the correct account.

Alternative Repair Methods

If the above method does not help:

• log out of Office in File > Account, close all applications, and log in again,
• delete saved MicrosoftOffice credentials in Windows Credential Manager,
• disconnect incorrect accounts in Settings > Accounts > Access work or school,
• check if the system date, time, and time zone are correct,
• completely uninstall Office and reinstall the correct version,
• ensure you don't have multiple editions of Office installed at the same time,
• in Microsoft 365, check if the account has an active subscription and available device limit.
