Watermarks are not visible in WOPI edit mode.

hi vijayrathod7​ What you’re seeing is most likely by design, not a WOPI host issue. In Word/Office documents, traditional watermarks are usually implemented as header-layer objects. Microsoft’s own guidance also notes that watermark creation/editing support is limited in the web editor, which is a clue that rendering behavior in edit mode is not the same as in reading/print/PDF output. In other words, the editing canvas is optimized for document authoring, not for faithfully showing every page-background element exactly as it appears in print.

That lines up with your symptoms:

• Visible in reading mode
• Visible in PDF/export
• Not visible in edit mode

So this usually points to the Office for the web rendering layer in edit mode, rather than a problem in your WOPI integration itself.

A few practical notes:

I would not expect a WOPI host setting alone to change this behavior.

It may vary a bit by document format and watermark type, but in general edit mode is the least reliable place to validate watermark visibility.

If watermark visibility during authoring is a hard requirement, the common workaround is to use something more explicit than a classic watermark, such as:

• header text
• a visible banner / cover page marker
• sensitivity labeling / document protection patterns, depending on the scenario

So my take: this looks like a web editor limitation / expected rendering behavior, not something you’re necessarily misconfiguring. If this is a compliance requirement, I’d treat “visible in edit mode” as a product gap and raise it through Microsoft support or feedback channels.
