Office 365 Lync Online There was a problem acquiring a personal certificate

There was a problem acquiring a personal certificate required to sign in. If the problem continues, please contact your support team.

If you are still experiencing issues after trying out Microsoft’s help with removing certificates and Credentials from the Credentials Manager found here it might be because you have setup Federated Single Sign on and have a self-signed or untrusted certificated publishing your ADFS

The best way to resolve this issue is to trust the certificate of your ADFS published site or alternatively stop being so cheap and purchase a certificate online 🙂 However I am cheap and therefore used the following steps to trust my self-signed certificate.

Go to the HTTPS address of the ADFS published site ( and click certificate error in the URL Navigation bar.

Then click View Certificates

Once the Certificate tab opens click Install Certificate

Click Next

Select Place all certificates in the following store and Browse to ‘Personal’ and select OK

Click Next

Click Finish

Now you will need to do the procedure again but this time adding the certificate to ‘Trusted Root Certification Authorities’

Once completed you should be able to now sign-in on Lync 2010 Online for Office 365!

Publishing Anonymous InfoPath form for SharePoint 2010 Internet Sites

We were working on our new SharePoint 2010 Internet site today here at G&T and had some issues without contact form not allowing anonymous users to submit contact us forms.
We had done everything right, or so we thought. After getting the below errors and a lot of head scratching and googling we managed to get everything resolved.

Unknown SPRequest error occurred. More information: 0x80070005
The XSN is null and its not a cross server issue. Most likely a permission issue
  1. Allow Anonymous Access via Central Administration
    Application Management > Manage Web Applications > Authentication Providers > Enable anonymous access
  2. Disable Viewformpageslockdown
    Open SharePoint 2010 Management Shell

    get-spfeature -site URL
    $viewformlockdown = get-spfeature viewformpageslockdown
    disable-spfeature $viewformlockdown -URL
  3. Enable Anonymous access via the Site Collection
    Goto http://URL/_layouts/user.aspx
    Anonymous Access > Entire Web site
  4. Enable Add Items to List for Anonymous users

Big thanks to Russ Maxwell for his post on the above PowerShell ViewFormLockDown solution
