    Hello.  Whenever I attempt to attach a Skype invitation to an Outlook meeting, I receive the following error:

    "Create Skype Meeting failed. Please make sure that Skype for Business is running and signed-in and try again."

    When I go to Skype and click the gear/settings icon, and then click Meet Now, I get the error:

    "An error occurred during the Skype Meeting"

    Clicking that link, yields a dialog box:

    "An error occurred during the Skype Meeting. The action couldn't be completed. Please try again later.".

    Our IT has reinstalled office. It didn't help.  It used to work on my previous Windows 7 laptop. Nothing as far as I know has changed regarding my domain setup.  However, since there is a new PC image, could something be wrong with my local settings?  The outlook plugin is enabled, so is the VBA plugin. This also occurs when invoked from Skype directly so I don't think Outlook is the issue.

    I have verified that the VBA plugin for Outlook is running; though, I had to change the startup behavior to ensure this.  However, since the error occurs directly from Skype, there is probably something else wrong.

    Edit - I enabled logs and receive the following logs when trying to Meet Now:

    Hi Eric,

    According to the error message, it seems that you didn’t SFB client when you schedule skype meeting. Normally, when you try to schedule skype meeting, you must let your SFB client run, please make sure you open SFB client.

    For this issue, did that happen to specific client/PC?

    Is that the internal user or external user?

    If the issue only happen to specific client, please try to rebuild user profile. For your computer, please try to do a clean boot.
    https://support.microsoft.com/en-us/kb/929135

    Also make sure your client has the latest update.

    If it is an external user, skype meeting externally is managed by the Reverse Proxy. You need to publish simple URLs using reverse proxy. Are you able to resolve meet.yoursipdomain.com and telnet to this name/IP externally? Please check it.

    If all users had the issue, please check if there are any event IDs in SFB application log.

    Best Regards,
    Alice Wang

    Hi Alice.

    Thank you for your reply.

    As mentioned, I am able to create the error directly from SFB without any Outlook involvement.  A snip of relevant SFB error logs are present in the previous post, specifically:

    03/14/2018|10:30:26.205 2570:358C WARN  :: GenerateSecureRandomBytes - Could not acquire a cryptographic server handle 8009001a
    03/14/2018|10:30:26.205 2570:358C INFO  :: CUccConfInformation::Initialize - secure conference Id not created
    03/14/2018|10:30:26.205 2570:358C INFO  :: Function: CUccConfManagerSession::CreateConferenceInformation
    03/14/2018|10:30:26.205 2570:358C ERROR :: HRESULT API failed: 80004005 = hr

    Any idea what can cause GenerateSecureRandomBytes() to fail?

    I rebuilt the user profile.  It did not help.

    The issue occurs only on my PC, others on the corporate network are not having any issues with SFB.  I am attached to the domain via my Active Directory account as usual.

    I would assume the meet.oursipdomain.com is reachable as SFB is able to login for normal message sending.  Is the SIP server usually different then the server for messaging?  I will check with IT on this point to verify connectivity.

    Thoughts?  I hope to resolve this soon as it has been a couple of weeks already and I am running out of low hanging fruit ideas.  Please double check the logs above.

    Thanks.

    -Eric

    Hi Alice.  

    I am still waiting for a response on this item.  Any progress?  There should be a direct correlation between the API errors returned and one or more possible root causes.  Additional direction at this point would be very helpful as we have exhausted the obvious options on our end.

    Thanks

    Hi,

    Thanks for your response.

    Like tuochtro mentioned, the issue only happen to your own PC, so we suggest you update your OS to latest then try to do a clean boot on your computer, then test again.

    Alice Wang

    Alice, Tuochtro,

    This is a pretty unsatisfying answer.  The OS installation and Office installation are fresh.  Yes, this is only happening on my PC, but the root cause is unclear and there is a clear stack trace from the log.  My ask is that you come back with one or more potential causes of the failure in the top level function of the provided call stack.  Then perhaps I can resolve the issue without formatting my work laptop which is quite costly in terms of time / productivity.

    Please look more closely so I can resolve this quickly.

    One additional thought:  Is there a FULL installer for Skype for Business.  Perhaps that will help as opposed to removing Office / reinstalling Office and then applying the latest SFB update.

    Thank you.

    -Eric

    Solved!

    Enable Skype logs.  The following was revealed:
    03/14/2018|10:30:26.205 2570:358C WARN  :: GenerateSecureRandomBytes - Could not acquire a cryptographic server handle 8009001a

    Look up the API on the MSDN. This yields:
    https://social.msdn.microsoft.com/Forums/en-US/f3ae9010-d5c0-4fd2-a863-b4527a605050/error-8009001a?forum=theforumofsho

    Observe the specific error code, 8009001a:
    The pszContainer key container was found but is corrupt.

    Google for a practical example of others having this error code:
    https://social.msdn.microsoft.com/Forums/en-US/f3ae9010-d5c0-4fd2-a863-b4527a605050/error-8009001a?forum=theforumofsho

    Delete the corrupted CSP object directory.
    C:\Users\<user name>\AppData\Roaming\Microsoft\Crypto\RSA\S-1-5-21-1944583665-746140858-2620156293-15751

    Restart skype, test ‘meet now’ from the Skype app.  Verify no error. 
    Test outlook meeting, verify no error.
