Bitdefender Antispam causing email header info to display (for one sender only)

HELP, PLEASE!

After installing Bd (consumer level) on the weekend, emails from one sender only [as luck would have it, my primary work provider] are displaying as ascii-style type in older Outlook desktop email client and smothering intentional content in header information. The problem is clearly local, as the same emails display just fine in browser Webmail.

How do I turn off header display and return appearance to HTML in my Outlook desktop email client? Switching email management to browser is not a good solution for my workflow. Nor, obviously, is decoupling Bd from the email client. To be clear, messages are being allowed through. The problem is with the display.

Tried so far: I have whitelisted sender's email address and URL within email client settings and Bd. After closing Outlook and restarting system, the issue has not resolved for new messages.

Has anyone else encountered this problem and found a solution? This will quickly cause major disruption to workflow if not resolved.

Thanks in advance. K

Hello,

There are a few posts regading email content display issues encountered by users recently. Now, I'm not sure if the issue you described is related, but as a possible workaround, try to temporarily disable the Encrypted Web Scan feature located in the Online Threat Prevention module, and check again if the text is displayed correctly.

If the screenshot of my Outlook 2021 looks familiar to your situation, disabling the Encrypted Web Scan in Bitdefender and the Bitdefender Add-In on Outlook desktop client did not fix the issue for me. Accessing my email account via webmail was fine. My affected email account is POP3 but another account in Outlook which is IMAP, was not affected. Uninstalling Bitdefender was the only solution for me after several hours of wasted time trying to resolve this at my end, but I can now read all new emails coming in. I switched over to Windows Security as a temporary measure until Bitdefender finds a fix.

I'm having the same problem, but it started on the 12th August 2025. Recevied an email from a supplier on the 11th, all was fine. Got a new email on the 12th and the header was now showing. Anyone else have a solution that doesn't include disabling bd?

Hello,

The developers reverted the changes made in the last signature update and this should do the trick until a permanent fix is deployed. Click on update in systray and reboot once completed. But keep in mind this change is being rolled out gradually, so it may not reach everyone at the same time..
