AWS appstream2: Clarify OneDrive/Azure AD admin consent behavior

Service: appstream2 · 2026-09-30 · Documentation medium

File: appstream2/latest/developerguide/onedrive.md · Type: authz

Summary

Rewrites guidance on Microsoft Azure AD consent for OneDrive integration, explaining tenant-wide admin consent and the 'Reuse existing Microsoft consent' option versus per-user consent prompts.

Security assessment

Documents how OAuth/application consent is granted in Azure AD for the OneDrive integration, clarifying admin-consent vs end-user-consent flows; this is security-adjacent authorization guidance rather than a fix for a specific vulnerability.

Evidence

Your Azure Active Directory environment, not WorkSpaces Applications, decides whether users can consent on their own or need administrator approval.

+Your Azure Active Directory environment, not WorkSpaces Applications, decides whether users can consent on their own or need administrator approval. If your environment requires administrator consent, an administrator must grant consent to WorkSpaces Applications for the whole tenant. Then select **Reuse existing Microsoft consent** for each domain, as described in [Enable OneDrive for Your WorkSpaces Applications Users](./enable-onedrive.html). If that option is cleared, users are prompted for consent every time they link their account, and users who can't consent on their own are blocked even after an administrator grants consent.
