Re: Exchange Server error in '/owa' application
Hello all, I installed Exchange 2013 CU23 on our standalone server and got the same issue: Exception type: ExAssertException Exception message: ASSERT: HMACProvider.GetCertificates:protectionCertificates.Length<1 The Exchange Auth certificate wasn't expired though. Anyway I tried generating a new certificate and publish it. It didn't resolve the issues. Even after 2 hours of waiting. After all (before trying the last resort option to uninstall CU23) I tried using the old valid certificate and published it using the same procedure as described https://docs.microsoft.com/en-us/exchange/troubleshoot/administration/cannot-access-owa-or-ecp-if-oauth-expired. After that OWA and ECP returned back to life. With the best regards, Marat262KViews1like0Comments
