Windows Add-in Logs

The local log of the add-in installed via the MSI package is located here: C:\Logs\ExpressMeetingAddIn<date>.log.

The logging level is configured in the serilogSettings.json file in the add-in installation folder. If you need a full detailed log for debugging, set the MinimumLevel.Default and MinimumLevel.Override.Default attributes to Verbose in the file. This level is not suitable for permanent use: it increases the log size and may slow down performance.

You will also need the configuration file ExpressMeeting.dll.config from the add-in installation folder (e.g., C:\Program Files\eXpress\ExpressMeeting).

If a branded app is used, the name may differ from Express.


Outlook Web Access Logs (macOS)

Client-side logs for the OWA add-in are unavailable. Diagnostics must be performed using server logs.

Outlook Add-in Server Logs

Азк Administrators: Collecting the Add-In Server Logs

Logs for the add-in backend using AD authentication are stored by default in the following server folder:

C:/logs/core-service/

The folder path is specified in the configuration file appsettings.Production.json under the key:

Serilog.WriteTo[Name ="Logger"].Args.configureLogger.WriteTo[Name="File"]. Args.path

See the add-in installation guide for administrators.

To collect logs for the add-in backend with Keycloak authentication, run the following commands:

docker logs express-meeting-core-service-main &> /tmp/core.log
docker logs express-meeting-template-service-main &> /tmp/template.log
