Question

In our company, the MFA policy is set up using conditional access to request MFA every 15 days. However, there is an issue with Outlook that sometimes prompts users for MFA more than five times a day.

Hi @Jhomer Somon Fulcar

Thanks for your reply!

Based on my search, there are reports of compatibility issues between the Trellix Data Loss Prevention (DLP) agent and Microsoft Outlook, especially with Exchange accounts.

Here are the key takeaways:

Outlook Performance Impact: Trellix acknowledges that DLP endpoints can impact Outlook performance, especially when sending emails. They recommend enabling Microsoft Exchange Cache Mode to mitigate this issue.

For the general situation when Outlook asks for password questions, you can try the following automatic check and provide possible solutions to fix the detected problem.

If the problem persists, you might want to reach out to Trellix support for more specific guidance or consider temporarily disabling the DLP agent to see if it resolves the issue.
