As of today I cannot open Outlook through Firefox.

Message:

n error occurred during a connection to outlook.live.com. Invalid OCSP signing certificate in OCSP response. Error code: SEC_ERROR_OCSP_INVALID_SIGNING_CERT

Hi

Unfortunately Microsoft has misconfigured a security feature (OCSP stapling) on their servers which got now cached in your local firefox installation.

In order to resolve that, please enter about:config into the Firefox address bar (confirm the info message in case it shows up) and search for the preference named security.ssl.enable_ocsp_stapling. Double-click it and change its value to false - this will degrade a security feature in Firefox, so please revisit it in a couple of days again after Microsoft has fixed their stuff and turn it back on again then.
