3) Question: Does Second Chance work with Outlook Web Access?

Answer: No. Outlook Web Access is not supported.

4) Question: Can I have a list of KnowBe4's No Prompt Domains?

Answer: For security reasons, we can not share a list of our No Prompt Domains. Additionally, since the list is constantly changing, the data on the list would become outdated quickly.

5) Question: My users are clicking Continue but their browser window isn't appearing.

Answer: The browser window will not appear as a pop up on the screen after clicking, so it has most likely been opened. Depending on the default browser, there may be a flashing browser icon in the taskbar indicating a new link has been opened. Instruct your user to double-check their browser after clicking the Second Chance prompt to continue to the website, as it should have been opened.

6) Question: After installing Second Chance, I'm getting an error when I open Excel.

Answer: The error message The program can't start because MSVCR90.dll is missing from your computer. Try reinstalling the program to fix this problem is due to a known compatibility issue with Windows 10, Excel 2010, and Sophos/Hitman Pro.

7) Question: How is my data encrypted?
