Can I use multiple CSP partners for different Microsoft products?

In practice, it's uncommon and adds complexity, but Microsoft's licensing model is generally structured around a single partner-of-record per product per tenant at any given time — not a strict technical block on using different partners for different products, but it does mean more invoices, more admin relationships, and more coordination if something goes wrong.

Why most customers consolidate

• One partner across Azure, Microsoft 365, and Dynamics 365 means one invoice and one point of accountability.
• Troubleshooting a billing or licensing issue is simpler when a single partner has full visibility into your account.

If you do have reasons to split (e.g. a specialist partner for one product), it's worth confirming with each partner how overlapping admin access will be managed.
