How to make Outlook Sync working with ESET Antivirus / Smart Security

Follow the latest recommendations below and turn off selected options to make the Outlook Sync work smoothly with Microsoft Outlook 2016/2019 or 2021.

1. EMAIL PROTOCOLS (IMAP & POP3)

2. EMAIL CLIENTS (INTEGRATION WITH ESET ADDON)

3. THREATSENSE PARAMETERS (OBJECT SCANNING)

4. EXCLUSIONS (OUTLOOK FILES)

We advise modifying the following exceptions (the path can vary):

DETECTION ENGINE > EXCLUSIONS > Detection exclusions - Add path to Outlook's pst folder, by default in C:\Users\%USERNAME%\Documents\Outlook Files\*.*

WEB and EMAIL - Email client protection - Threatsense parameters - Exclusions - Edit - Add
tmp
pst
ocsql

ESET on the WINDOWS SERVER

In case you have ESET on the server, please add localhost to the exception:
Setup - Advanced setup - WEB and EMAIL - Protocol filtering - Excluded IP address - Edit - add 127.0.0.1

IMPORTANT:
Please note that you should create a brand new profile once you install ESET to avoid possible synchronisation issues.
