ESET settings adjustments for Outlook Sync

Please follow the steps below to address the synchronisation issues caused by the ESET Antispam/Antivirus solution available in Microsoft Outlook. 

Adjusting ESET settings will not put your computer at risk or turn off the protection entirely. Your data will continue to be protected by the antivirus running on the IceWarp Server.

If you have another product from ESET or manage ESET from the Management Console on the server, and you happen to see issues with the synchronisation in Outlook Sync, don't hesitate to contact our support for further recommendations.

Options below are available under the path SETUP - ADVANCED SETUP, and screenshots used in the following guidelines are taken on a Windows 10/11 device using ESET Endpoint Antivirus 9.1.

1. Integration with Outlook

Path: WEB AND EMAIL - EMAIL CLIENT PROTECTION - EMAIL CLIENT INTEGRATION

2. Email protection by client plugins

Path: WEB AND EMAIL - EMAIL CLIENT PROTECTION - EMAIL CLIENTS

3. Objects to scan and Scan options

Path: WEB AND EMAIL - EMAIL CLIENT PROTECTION - THREATSENSE PARAMETERS

4. Detection exclusions

Path: DETECTION ENGINE - EXCLUSIONS

Add path to Outlook's pst folder (default path is C:\Users\%USERNAME%\Documents\Outlook Files\*.*)

5. File extensions excluded from scanning

Path: DETECTION ENGINE - EXCLUSIONS

Add file extensions excluded from scanning according to the screenshot

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:
A new Microsoft Outlook Profile is always recommended when you install ESET for the first time on your device to avoid possible synchronisation issues
