WebMail Lite Documentation

Office document viewer

Default viewer

To view files of office document formats such as .DOC or .XLSX, WebMail Lite uses an online viewer from Microsoft.

If you experience issues with viewing those files, you can try switching to a viewer from Google.

In data/settings/modules/OfficeDocumentViewer.config.json file, set ViewerUrl value as follows:

"ViewerUrl": [
    "URL of external web service used for viewing files"

Please note that in either case, your WebMail Lite installation needs to be accessible over the web, so that online viewer can have access to it. Viewer from Microsoft is also known to fail at displaying the document if your WebMail Lite installation is accessed via IP address rather than domain name.
