Certificate has expired or is not yet valid *.office.microsoft.com

    Question

  • Starting yesterday Outlook 2007 clients who have webcals with office.microsoft.com started getting messages stating the certificate expired 8/25/2010.  Is anyone else getting this?

  • Hi!

    The existing certificate for *.office.microsoft.com had expired and a new one was published soon after.

     

    Any Office applications may have accessed various Office-related sites after the older certificate had expired, resulting in the security warning.

     

    You can check which features may have accessed these related sites by clicking on File (or Tools in Outlook 2007) | Options | Trust Center | Trust Cetner settings. In the Privacy Options grouping, any of the first 4 options can access these sites, if enabled.

    Thanks for posting!

  • I think someone at Microsoft forgot to apply the latest cert to the office.microsoft.com server.  That or someone forgot to even apply for the new one.

     

    I am reminded of years ago when the file extension open with search was being run from a developers box in an office somewhere and nobody realized it until one day they took out the box for development reasons and poof all the Windows clients in the world who chose to search for extension handler were sol.

     

    This cert expiration issue seems like a similar goof has happened.

  • The certificate expiration prompts for webcals seem to have gone away sometime this afternoon.  Hopefully someone can post more information on the details of what occurred so we have information for the future.

  • Is this type of time gap in certificate validity going to be a norm?  This goes against the 99.x% uptime that most customers have come to expect.  I don't know that office.microsoft.com has stated an expected uptime but in the industry what was once acceptable at 99% has increased to as high as 99.99% in some cases.  This one 24 hour downtime took a chunk out of the year's uptime percentage.

  • July 1, 2011 and the problem has occurred again. Guess we need to wait for someone at Microsoft to fix this...

  • I can confirm for you that our Office 2010 machines received the expired certificate warning starting today as well.
