- Scenario
- Deploying Office 2019 to an educational staff device via volume licensing.

Activate Office 2019 Using the Volume License Serializer
Deploy the Volume License Serializer to activate Office on a Mac without requiring individual Microsoft account credentials.
For volume license environments like schools, Microsoft provides a specific tool called the Volume License (VL) Serializer. When this package is run on a Mac, it activates Office at the machine level.
This completely bypasses the need to type in administrator Microsoft account credentials when launching the applications.
Sign in to the Microsoft 365 Admin Center or Volume Licensing Service Center (VLSC) to download the Office 2019 for Mac installer (.pkg) and the VL Serializer tool.
Run the Office 2019 installer on the target Mac and complete the standard installation process.
Close any open Office applications, then run the Volume License Serializer package to inject the license key into the system.
Open Microsoft Word or Excel. If a sign-in screen appears, click 'Skip sign in' to proceed directly to the activated software.

Frequently Asked Questions
Can I activate Office 2019 for Mac without a Microsoft account?
Yes, for volume-licensed software, your IT department can use the Volume License (VL) Serializer to activate Office 2019 without logging in.
Where can school administrators find the Volume License Serializer?
The VL Serializer can be downloaded directly from the Microsoft 365 Admin Center under the Volume Licensing section or via the legacy Volume Licensing Service Center (VLSC).
