This article guides you through troubleshooting steps if the Bitdefender Antispam toolbar is missing from Microsoft Outlook. Normally, the Antispam toolbar appears in the upper ribbon of your Outlook window to help you manage spam protection directly from the email app.
Step 1: Check If You Have an ARM-Based PC
The Bitdefender Antispam toolbar does not support ARM-based Windows computers.
To find out if your device is ARM-based, follow the instructions in this article:
Step 2: Ensure You’re Logged In as an Administrator
The Antispam toolbar only works with Windows accounts that have local administrator rights.
To verify your account type, refer to this guide:
Step 3: Verify Compatibility with Your Email App
The Bitdefender Antispam toolbar is compatible with:
- Microsoft Outlook versions 2007, 2010, 2013, 2016, 2021
- Mozilla Thunderbird version 14 and newer
If your email app is not compatible, Bitdefender will still scan emails for spam and malware as long as you’re using the default account settings (POP3 on port 110 for incoming server; SMTP on port 25 for outgoing server).
Step 4: Ensure the Antispam Feature Is Enabled
- Close Outlook or your email app.

- Restart the Bitdefender Agent:
