Hello, 

I'm trying to run Lync Shell command (Get-csClientcertificate)  for one user account and it throws up the below error:

##50012: CertStoreGetUserCerts: user@domain.com is temporarily unavailable.,Microsoft.Rtc.Managment.UserPinService.GetOcsUserCertsCmdlet

This command works just fine for all other users. Only this particular user is unable to signin and this command doesn't work for this account,  Communicator.Uccapil logs says the following:

ms-diagnostics-public: 4050;reason="From User is either disabled or moving away"

I  tried the following solutions:

>> Disabled and enabled the user account  on lync--> no luck.

>> Deleted from AD and recreated the account, then enabled the user account in lync --> no luck. 

>> Removed the user account from lync server and recreated it --> no luck.

I believe something we need to focus on the client certificate part. 

Can anyone help me on this?

Thank you for your update. I moved this user account from OCS to Lync. It  was working just fine, suddenly the specific user got this issue (for all other users no issues). I tried with all the computers and issue is same. I ran the commands for this user account(Get-Csclientcertificate &Revoke-CsClientcertificate) and received the below error message:

Get-CsClientCertificate : ###50012:CertStoreGetUserCerts: user@domain.com is temporarily unavailable.
