How can I configure Microsoft Word/Excel to get timestamps from ADSS TSA Server?

In order to create a time-stamped signature (XAdES-T signatures) MS Word/Excel or InfoPath, you’ll need to:

By default, Office 2010/2013 creates XAdES-EPES signatures. Registry settings are used to specify the level of signatures to be created. There are two registry settings to control the type of signature Office creates XAdESLevel and MinXAdESLevel. The MinXAdESLevel setting allows you to ensure that created signatures meet your required XAdES level. A XAdES-T or higher signature will fail if the timestamp server isn’t available. Having a minimum setting allows scenarios where you could attempt a XAdES-T signature, but fall back to XAdES-EPES if the timestamp server is down.

Follow these instructions to configure ADSS TSA Service URL:

  1. Launch Microsoft Word/Excel, open a document and create a XAdES signature so that the relevant entries are created in the Windows Registry
  2. Open regedit and navigate to the folders: HKEY_CURRENT_USER > SOFTWARE > Microsoft > Office
  3. Select the numbered folder which matches the installed version of Microsoft Office:
    1. For MS Office 2016 and Office 365 select folder 16.0
    2. For MS Office 2013 select folder 15.0
    3. For MS Office 2010 select folder 14.0
  4. Navigate to the respective folders and then Common > Signatures e.g. HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Signatures
  5. Create a new DWORD entry and name it XAdESLevel. Set it to 2 (to create XAdES-T signature), hence creating a timestamp signature
  6. Optionally create another DWORD and this time title it MinXAdESLevel. Set it to 1 (XAdES-EPES) or the more strict 2
  7. Create a String Value and title it TSALocation. Enter the URL of your ADSS timestamp server e.g. http://machinename:8777/adss/tsa
