Latest Message<\/th>\nTitle: Some users may be unable to access Planner on the web<\/p>\n

User impact: Users may be unable to access Planner on the web.<\/p>\n

More info: To bypass the impact, some users may be able to access Planner via Microsoft Teams if this option is available to them.<\/p>\n

Current status: We’ve confirmed that an update to the Planner Microsoft Authentication Library (MSAL) is introducing a mismatch between the unauthenticated Planner on the web landing page and the authenticated experience after users sign in. This mismatch is resulting in the impact. We’ve updated the MSAL to be aligned across both experiences, and we’re validating this has resolved the issue with a subset of affected users.<\/p>\n

Scope of impact: Some users that are trying to access Planner on the web may be impacted.<\/p>\n

Start time: Monday, March 2, 2026, at 7:15 AM UTC<\/p>\n

Root cause: An update to the Planner Microsoft Authentication Library (MSAL) is introducing a mismatch between the unauthenticated Planner on the web landing page and the authenticated experience after users sign in. This mismatch is resulting in the impact.<\/p>\n
