Question details

Organizations moving their Microsoft 365 E3 subscription from the MPSA channel to the CSP channel need to determine if a separate Teams license is required upon renewal.

How to Manage Microsoft 365 E3 Licensing Change from MPSA to CSP Without Teams

Product: Microsoft 365 E3
Device & OS: not provided
Scenario: Migrating a corporate enterprise subscription from Microsoft Products and Services Agreement (MPSA) to a Cloud Solution Provider (CSP) channel.
Observed behavior: Because the purchasing channels differ, organizations may discover that their new CSP Microsoft 365 E3 plan does not include Teams, requiring the acquisition of dual SKUs at renewal.

Before you start

Ensure you have global administrator access to your Microsoft 365 Admin Center and the direct contact information for your new Cloud Solution Provider (CSP) partner.

Solution 1Recommended

Coordinate with Your CSP Partner for Separate Teams Licensing

Confirm your exact licensing structure with your CSP partner and provision the necessary standalone Teams SKUs alongside your base E3 subscription.

Microsoft has introduced licensing changes that separate Microsoft Teams from core enterprise suites in certain purchasing channels and regions. When moving from MPSA to CSP, your existing bundled E3 license might be replaced by a 'Microsoft 365 E3 without Teams' SKU.

Contact your direct CSP partner

Reach out to your CSP representative before your MPSA renewal date to request an audit of your current MPSA Microsoft 365 E3 licenses.

Request the appropriate SKUs

Instruct your partner to quote and provision two separate items if your workforce requires chat and meeting features: the 'Microsoft 365 E3 without Teams' SKU and the standalone 'Microsoft Teams Enterprise' SKU.

Verify license availability in Admin Center

Once the CSP provisions the licenses, log in to the Microsoft 365 Admin Center, go to Billing > Your products, and confirm both the E3 base license and the standalone Teams license appear as active.

Assign licenses to users

Navigate to Users > Active users. Select the relevant employees, click 'Manage product licenses', and ensure both the new E3 base license and the standalone Teams license are checked before the MPSA license expires.

Coordinate with Your CSP Partner for Separate Teams Licensing

Avoid Data Loss: Assigning the new CSP licenses before your old MPSA subscription expires ensures continuous service, meaning users will not lose access to their Teams chats, files, or meeting histories.

Frequently Asked Questions

What is the primary difference between MPSA and CSP purchasing channels?

MPSA (Microsoft Products and Services Agreement) is a transactional volume licensing agreement intended for medium-to-large organizations purchasing software and cloud services. CSP (Cloud Solution Provider) is a partner-driven model where you purchase cloud subscriptions and receive direct billing and support through an authorized Microsoft partner. Their catalog SKUs frequently differ.

Why is Teams excluded from my new Microsoft 365 E3 CSP subscription?

Microsoft recently unbundled Teams from its core Enterprise suites (E3 and E5) in various global regions. New subscriptions purchased through channels like CSP often require you to buy the base productivity suite (without Teams) and a separate Teams standalone license.

Will my organization experience downtime during the transition from MPSA to CSP?

No, as long as your CSP partner provisions the new licenses and you assign them to your users in the Microsoft 365 Admin Center before the MPSA expiration date, the transition will be seamless and user data will remain fully intact.
