By default, the ESET Antispam toolbar will appear in Microsoft Outlook, Outlook Express and Windows Live Mail (version 2012 and earlier) when you install ESET Smart Security Premium, ESET Smart Security or ESET Internet Security.
This toolbar enables you to quickly designate messages as Spam or Not spam and categorize an email address as a Trusted address (Whitelist) or a Spam address (Blacklist).
To add or remove the ESET Antispam toolbar, follow the instructions below:
Press the F5 key to access Advanced setup.
Click Web and Email → Email client protection. Select or deselect the slider bar next to your email client and click OK to save your changes.
