Hello,

Microsoft forgot to renew the certificate and it expired, so the message is correct. You can simply click on the «Continue» button and wait for Microsoft to update the certificate. Also please see post @Flood and Flood's wife with workaround.

Hi all, the certificate is indeed expired, Microsoft should fix this issue promptly.

Please check problem again. MS probably updated the certificate already.
