Solution 1Recommended

Upgrade to an Eligible Enterprise Base License

To use Microsoft 365 F5 Security and Compliance add-ons, you must first upgrade your users from Business Standard to a qualifying Enterprise base license.

Microsoft restricts certain enterprise add-ons from being applied to Business-tier subscriptions. Add-ons only appear in the admin center if the corresponding base license prerequisite is met.

1
Access the Microsoft 365 Admin Center

Log in to the Microsoft 365 admin center using your global administrator or billing administrator credentials.

2
Upgrade the base license

Navigate to 'Billing' and select 'Purchase services'. Purchase a qualifying base license for your users, such as Microsoft 365 E3, Office 365 E3, or Enterprise Mobility + Security E3.

3
Assign the new base license

Go to 'Users' > 'Active users', select the specific users, and assign them the newly purchased Enterprise base license while removing the Business Standard license.

4
Purchase and assign the F5 add-on

Once the eligible base license is active on the user accounts, return to 'Purchase services' to buy the Microsoft 365 F5 Security and Compliance add-on, then assign it to those users.

Upgrade to an Eligible Enterprise Base License
Trial Requirements: Even if you only want to start a Microsoft 365 E5 Compliance trial, you will still need one of the eligible E3 base licenses mentioned above.

Frequently Asked Questions

What are the qualifying base licenses for Microsoft 365 F5 add-ons?

Eligible base licenses typically include Microsoft 365 E3, Office 365 E3, or Enterprise Mobility + Security E3. You cannot attach these enterprise add-ons to Business-tier subscriptions like Business Standard.

Can I start an E5 Compliance trial with Microsoft 365 Business Standard?

No, starting a Microsoft 365 E5 Compliance trial also requires a qualifying enterprise base license. Business Standard does not meet the prerequisite for this trial.

Why do certain security add-ons not appear in my Microsoft 365 admin center?

Available add-ons are displayed based on your current base licenses. If your organization only uses Business subscriptions, Enterprise-level add-ons like F5 Security and Compliance will remain hidden and unavailable for purchase.
