For Calendar Sync:

Note: Starting from WMS 5.03, it is possible to sync calendars and update users statuses automatically, without Outlook. Consult the Guide Microsoft 365 Integration Guide for details.

Make sure that Wildix Outlook Integration is active in Outlook Options -> Add-ins. To add Wildix to Add-Ins:

Current limitation: Android Collaboration App vs Outlook Calendar

  • It is not recommended to enable option “User status when talking on mobile” on Android Collaboration App (Advanced Settings) in case of using Outlook Calendar Integration: after completing a mobile call, user status might not be able to go back to its previous state due to the Outlook Calendar sync, and might remain incorrect.


Install WIService

Outlook integration is part of the WIService starting from WIService v. 3.5.1. So, to enable Outlook integration, WIService should be installed:

  • Go Collaboration Settings -> Extensions -> install Integration service:

For detailed instructions on how to install WIService, check this guide: What is WIService: Installation.

Activate Outlook Integration

Once WIService is installed, you need to activate Outlook integration in WIService settings:

  • Activate the option Enable Outlook Integration (admin rights required):

  • After the activation, Wildix Outlook Integration is available in Outlook Calendar:

    • click About  to check the integration version and open logs if needed

Starting from WIService v. 3.16.1, Outlook integration installation folder is in the WIService folder on Windows. 

Enable Outlook calendar sync

Go to Collaboration Settings -> Outlook (the tab appears after the integration is installed) and click the toggle switch Enable calendar sync:

Note: The calendar sync can take up to 10 minutes after you enable it. 

Important: Starting from WMS 5.04.20211228.2, in case Microsoft365 integration is enabled in WMS -> Settings -> PBX -> Integrations, Microsoft365 integration has higher priority, Collaboration syncs with Outlook Cloud, and the Outlook tab is replaced with Microsoft365 in Collaboration Settings.
