Office 365 License for Managed service provider

[Chandrasekhar_Arya]

I am using office365 E3 with an email ID abc@contoso.com , which entitles me for P1 License for contoso company  now If I have to support two customers (Customer A and Customer B)  and I was invited as guest do we need to have P1/P2 License for each customer ? or my existing Office 365 E3 license for abv@contoso.com is good enough ?

The customer is responsible for meeting the license requirements, either by using the new MAU-based licensing model or ensuring the 1:5 ratio is met, as detailed here: https://docs.microsoft.com/en-us/azure/active-directory/external-identities/external-identities-pric...
