HardIn work/school tenants on Microsoft's default consent policy, users can't consent to Mail.Read, Calendars.Read, Chat.Read, Files.Read.All and similar agent-relevant scopes, so every customer organization needs an admin to grant consent; unverified multitenant apps get stepped up to admin consent even for lesser scopes, which makes publisher verification (a verified Microsoft AI Cloud Partner Program account) the practical first step.

A multitenant SaaS agent reading mail, calendar, files or Teams chats with delegated permissions, made publisher verified; consumer (personal Microsoft account) users and low-risk scopes can work the same day.
- Waiting on
- Microsoft AI Cloud Partner Program business verification (three to five business days in most cases, longer if documents are requested) and DNS verification of your domain; after that, each customer tenant's admin granting consent, which has no SLA.
- Cost
- Free: no fee for publisher verification or Partner Program enrollment is stated. You need an Entra (work/school) tenant to register a verifiable app.
What you need first
A Microsoft Entra work or school tenant where you're at least Application Developer
Apps registered with a personal Microsoft account can't be publisher verified (MSANotSupported), and the app object can't be moved between tenants later.
A DNS-verified custom domain on that tenant (not *.onmicrosoft.com) matching your Partner Center primary contact email domain
Publisher verification fails with PublisherDomainMismatch unless the app's publisher domain or a verified custom domain matches the email domain used in Partner Center.
A verified Microsoft AI Cloud Partner Program (formerly MPN) partner global account
Its Partner One ID is what you attach to the app to get the blue verified badge. Location IDs are rejected.
A user with Application Administrator or Cloud Application Administrator in Entra plus CPP Admin or Account Admin in Partner Center, signing in with MFA
The verification call returns NotAuthorizedToVerifyPublisher, MPNAccountNotFoundOrNoAccess or InteractionRequired otherwise.
