DescriptionDuring the maintenance window, Service-Communications certificate on production ADFS server will be renewed and a new pair of Token-Signing and Token-Decrypting certificates will be generated. During the window, we expect short periods of downtime when users will experience authentication problems with signing in to Office 365 Portal to access email or other services in EDU and UofW tenants. Other systems that use ADFS for authentication will be affected as well.
If you are affected, we recommend to wait 10 minutes and re-try again â€“ the authentication problems are expected to be short-lived and normal operation should resume automatically. Certain systems, in particular Unit4, will require contacting the vendor to restore full operation after the maintenance.
