Which version of Outlook do these procedures apply to?

These procedures apply to Outlook Classic for Windows, also known as Outlook desktop.

Which method should I use?

  • Use Method 1 to analyze what happens when an email is sent.

  • Use Method 2 to analyze how the Letsignit task pane works.

  • Both methods can be used together depending on the situation.

Method 1:

Outlook Classic uses a JavaScript-only runtime that does not include browser Developer Tools. To record logs when an email is sent, logging must be enabled through the Windows Registry.

  1. Open the Windows Registry Editor by searching for regedit in the Start menu.

  2. Navigate to the following registry key:

    HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\WEF\Developer

  3. If the Developer key does not exist, right-click WEF, select New > Key, and name it Developer.

  4. Inside the Developer key, create a new String Value (REG_SZ) named:

    RuntimeLogging

  5. Set the value to the full path of the file where the logs should be saved, for example:

    C:\temp\outlook_addin_log.txt

    The specified folder must already exist, and your user account must have write permissions.

  6. Restart Outlook.

  7. Reproduce the behavior encountered when sending an email.

  8. Send the log file to the support team.

Important: This method only records activity related to the send event. It does not capture logs from the task pane or other interactions with the Add-in.

Method 2:

  1. Open Outlook Classic and click New Email.

  2. Click Preview my Letsignit signatures to open the Add-in.

  3. In the Letsignit task pane, right-click and select Inspect.

  4. In the Developer Tools window, open the Console tab.

  5. Reproduce the behavior encountered with the Add-in.

  6. In the console, right-click and select Save as.

  7. Save the file and send it to the support team.

Important: This method helps analyze errors related to the task pane and interactions with the Add-in. It does not replace Method 1 for issues that occur when the email is sent.
