Bitdefender Antispam toolbar is missing from Outlook

Before you start reading this document, please make sure that you are logged into Windows with an administrative account (for the operating systems that support this type of accounts).

Also, please note that the Bitdefender Antispam toolbar works only on accounts that have local administrative rights.


A. Check if the Antispam toolbar is compatible with your e-mail client

The Bitdefender Antispam toolbar is compatible with Microsoft Outlook (2007, 2010, 2013, 2016) and Mozilla Thunderbird (14 or higher).

NOTE: In case the toolbar is not compatible with your e-mail client, you should know that if you are using the default protocols and port numbers for the account settings (POP3, port 110 for incoming server; SMTP, port 25 for outgoing server), the e-mail traffic will be scanned for SPAM and malware.


B. Make sure the Antispam module is enabled

First, close the e-mail client. Then open Bitdefender, go to Protection and check if the Antispam module is enabled.

If the Antispam module was already enabled please follow the instructions below:

Go to Start -> type in cmd , right-click on Command Prompt and select Run as Administrator. In the Command Prompt type or copy & paste the following commands:

cd %programfiles%\Bitdefender\Bitdefender Security and hit Enter;

bdagent /stop and hit Enter then wait a few seconds;

bdagent and hit Enter;

Now, open your e-mail client and check if the Antispam toolbar appears in the e-mail client.


C. Unregister and re-register the Antispam toolbar if you are using Microsoft Outlook

If this is the first time you encounter this issue, it is possible that the Bitdefender Antispam toolbar is un-registered. In order to correct this, you’ll need to follow the steps presented below, while having Outlook closed:

1. Go to Start -> type in cmd.exe , right-click on Command Prompt and select Run as Administrator.

2. In the Command Prompt window type the following commands one after another:

regsvr32 -u “%ProgramFiles%\Bitdefender\Bitdefender Security\bdo.dll” and hit the Enter key.

regsvr32 “%ProgramFiles%\Bitdefender\Bitdefender Security\bdo.dll” and hit the Enter key.

3. If you are using a 64-bit Operating System and Microsoft Office x64, the commands are the following ones:

regsvr32 -u “%ProgramFiles%\Bitdefender\Bitdefender Security\antispam32\bdo.dll” and hit the Enter key.

regsvr32 “%ProgramFiles%\Bitdefender\Bitdefender Security\antispam32\bdo.dll” and hit the Enter key.

Restart your computer and check if the Antispam Toolbar is loaded in Microsoft Outlook.

4. If this is not the first time that you encounter this issue and/or the above step fails, then please open Outlook and go to: 

For Outlook 2007: Tools | Trust Center | Add-Ins | Manage -> COM Add-Ins -> GO

For Outlook 2010, 2013, 2016: File | Options | Add-Ins | Manage -> COM Add-Ins -> GO

In the window that will appear, you should see the Bitdefender Antispam component: 

If the Bitdefender Antispam plug-in does not exist in the Add-Ins list, then the component is not registered. You need to either run the commands presented above or to use the Add button; Browse to the Bitdefender installation location, select bdo.dll and click OK. After that please make sure that the component is checked, then click OK and restart Outlook.

If the Bitdefender Antispam exists and the option is checked but the toolbar does not appear (or you restart Outlook and the checkbox is un-checked automatically again) then this situation happened due to a Outlook crash.

In order to fix this please open Outlook, click on File, select Options, then click on Add-Ins. In the lower part of the window, in the field next to Manage, select Disabled Items from the dropdown list and click Go. Now, you will see a new dialog window from where you can enable the add-ins. Simply check the Bitdefender Antispam add-in to enable it.

After this operation you will be able to check the Bitdefender Antispam toolbar.
