I'd like to know which are the rate limits provided for the Microsoft Entra ID for Customers.

We've been using Microsoft Azure B2C in the past and we found out about the 200 request per second rate limit once in production. We'd love to plan carefully the usage of Entra ID for Customers since we plan to use it in production on customer who experience big spikes of traffic and signup/signin at the same time (thousands to hundreds of thousands).

Thanks

Hi @Federico Giacinti ,

Thanks for reaching out and apologies for delay in response.

As Microsoft Entra External ID (for customers) is in preview, so no rate limits details are available at this time.

The rate limits for existing B2B collaboration features are unchanged.

Hope this will help.

Thanks,

Shweta

    HI, B2C limits are listed here, but it sounds like you have already seen these?
