I *think* so. I don't really do much with workstations, but I believe they are getting those updates through the regular Windows process. I am personally experiencing the problem, and I looked at each cert in the chain through IE. Each level indicates "This certificate is OK".

Don't know if that is just me or what. Anyway... 12175 seems to be related to a certificate issue. However, the certificates all look good, and are trusted by IE if I manually put in the path to the XML. We did renew our certificate about 2 months ago, but this has been in place a while and I don't know why it would cause a problem at this point. I did previously check and make sure no certificates in Exchange did not show up as expired, and they don't. The only other thing I see here is that when I run "Test-OutlookWebServices" on a CAS, I do see a warning message that the name of the actual CAS server is not on the certificate. I can't honestly remember if the server names were on the old certificate, but I did use the wizard to generate the CRL. I am really stumped.

FWIW, here is some additional information from troubleshooting since I initially sent the message. 1) I downloaded and ran "autodiscovertest.exe"; I don't see any error messages there on the same computer/user for which I get a failure for Outlook. 2) I turned on Outlook logging and in addition to the "0x80072ef3" error, I note the additional message preceding that error is "GetLastError=12175; httpStatus=0." 3) Logging on with different accounts and onto different computers, it does not appear to be specifically following a user or computer. An account without the problem logged onto a different computer and had the problem there. An affected account logged onto the computer where the unaffected user did not have a problem, and still had the problem there.

Tested via OWA and the information is accessible. Did a lot of googling and found suggestions that it was tied to autodiscover. Tested autodiscover on a computer with the problem and it fails with an error 0x80072ef3. However, we have at least one computer where there is no problem with the calendars and autodiscover is working. I did a "Test-OutlookWebServices" on both CAS servers and that seems to be reporting OK. The only thing that I know of that is different with the computer that doesn't have a problem is that it hasn't had the same updates applied as a computer with the problem (it hasn't applied the last cycle). We also just received a report about a problem setting out of office, which I think also ties into autodiscover. We are on Exchange 2010 and Outlook 2010. Two CAS servers in an NLB, and they have both been rebooted. Any help or pointers would be appreciated. Bill Mayo
