How to Stop Excel 2021 From Requiring Sign-In on an Offline PC

Product: Microsoft Excel 2021
Device & OS: not provided
Scenario: Using standalone Microsoft Office or Excel on a computer without an active internet connection.
Observed behavior: Excel periodically interrupts workflow by requesting the user to sign in to verify the software license, which is impossible on an offline machine.

Before you start

You will need access to a separate computer with an active internet connection and a USB flash drive to download and transfer the offline license file.

Solution 1Recommended

Extend Office License for Offline Use via Microsoft Portal

Generate an offline license file using an internet-connected device and transfer it to your offline PC to satisfy the verification requirement.

Modern Microsoft Office products periodically connect to Microsoft servers to verify the validity of your license. If the computer remains offline, you must manually supply a verification file.

Access the Microsoft Office Portal

On an internet-connected device, open a web browser, go to the Microsoft 365 admin center or Office portal, and log in with your administrative account.

Generate an Offline License File

Navigate to the device management or license settings section to locate the option for extending offline access, and generate the offline license file for the target device.

Transfer to a USB Drive

Download the generated license file and copy it to a removable USB flash drive.

Apply to the Offline PC

Insert the USB drive into your offline computer and follow Microsoft's offline activation prompts to apply the license file.

Frequently Asked Questions

Why does Excel 2021 ask me to sign in when I bought a standalone version?

Even standalone, one-time purchase versions of Microsoft Office periodically connect to Microsoft's servers to verify the legitimacy of your license. When the software cannot reach these servers for an extended period, it prompts you to sign in to verify your account.

How long can I use Microsoft 365 offline before it requires a sign-in?

By default, Microsoft 365 apps require internet access at least once every 30 days to verify your subscription status. If 'Extended Offline Access' is enabled by an IT administrator, this period can be increased to up to 180 days.

Can I permanently disable the sign-in prompt on an offline PC?

No, current versions of Microsoft Office and Microsoft 365 do not allow you to permanently bypass license verification. You must either temporarily connect to the internet or manually apply an offline license file every few months.

Do I need an internet connection to use WPS Office?

You only need an internet connection to download the WPS Office installer. Once installed on your PC, you can use the core Word, Excel, and PowerPoint alternative features entirely offline without mandatory sign-ins.
