We recommend the JavaScript add-ins instead of this one.The COM add-ins are fully supported, but they install per user onto each endpoint and depend on the Microsoft VSTO runtime being present, which makes them more sensitive to how a Windows estate is built and managed. Across the environments we most often work in, the JavaScript add-ins are markedly more reliable to deploy and to keep working.If your organization meets all three prerequisites below, we strongly encourage you to deploy the JavaScript add-ins instead:
  • A Microsoft 365 tenant, with Global Administrator rights or equivalent permission to use Integrated apps in the Microsoft 365 admin center.
  • Endpoints that can reach dl.draftable.com, where the add-in manifests and runtime are served from.
  • A Draftable Legal desktop version at or above the minimum stated in each add-in’s installation article.
If you cannot meet those, the COM add-ins remain supported and this article still applies.Moving from the COM add-ins to the JavaScript add-ins is the step-by-step process, and COM add-ins vs JavaScript add-ins explains the difference in full.
This add-in is what we refer to as the COM add-in for Outlook. For our JavaScript-based add-ins, which offer completely different and more advanced workflows, see Draftable in Outlook and Draftable for Outlook.

​
Where do I find the Draftable add-in within Outlook?

Open any email that contains the documents or text you wish to compare. In the Outlook ribbon, select the Draftable tab to reveal the available comparison options.
You will see three options:
  • Compare attachments — Select email attachments to load into the New Comparison window
  • 1-Click Compare — Instantly run a comparison using your preferred default workflow
  • Compare text — Highlight text in the email body and load it into the New Comparison window
Each option is covered in detail below.

​
Compare attachments

Use this option when you want to compare documents that are attached to the email.
1
In the Draftable tab, click Compare attachments.
2
A prompt will appear asking you to select two files from the list of attachments on the email. Select the files you wish to compare, then click Select.
3
The New Comparison window will open with the selected documents loaded. Choose your comparison type and click Compare to start.

​
1-Click Compare

Use this option to run a comparison immediately using your default workflow settings, without needing to manually configure the New Comparison window.
1
In the Draftable tab, click 1-Click Compare.
2
Draftable will automatically compare the email attachments using your preferred default comparison settings. The comparison runs straight away without opening the New Comparison window first.
For more details on configuring your 1-Click Compare defaults, see 1-Click Compare: Run comparisons with your preferred default workflow.

​
Compare text

Use this option when you want to compare text from within the email body rather than file attachments.
1
In the email, highlight the text you want to use for comparison.
2
In the Draftable tab, click Compare text.
3
The New Comparison window will open with the selected text loaded into one of the document fields. Simply add your second document or text input and click Compare.
