How to Fix Word Bad Request Too Long Watermark Error
Question details
The user encounters an HTTP 400 error when attempting to add a custom graphic watermark or insert online pictures in their document.
- Product
- Microsoft Word
- Device & OS
- not provided
- Scenario
- Adding a custom picture watermark or using online picture commands to insert graphics into a document.
- Observed behavior
- Microsoft Word displays an HTTP 400 'Bad Request - Request Too Long' error and fails to load or apply the requested online content or graphic watermark.
Before proceeding, ensure you have the picture you want to use as a watermark saved locally on your computer's hard drive, as the workaround requires temporarily disconnecting from online services.
Disable Connected Experiences and Work Offline
This temporary workaround prevents Word from attempting to fetch online data, allowing you to bypass the HTTP 400 error and insert locally saved watermarks.
The 'Bad Request: Request Too Long' error is a known bug currently under investigation by Microsoft's development team. It is triggered when Word attempts to connect to online services to download pictures. By disabling these connected experiences, you force Word to rely entirely on local files, which successfully bypasses the connection error.
Open Microsoft Word and click on the 'File' tab in the top-left corner. Go to 'Options', select 'General' from the left sidebar, and click on 'Privacy Settings'.
Scroll down to the 'Connected Experiences' section. Find and uncheck the box for 'Experiences that download online content', then click 'OK' to save your changes.
Restart Microsoft Word. Go to the 'Design' tab, click 'Watermark', and select 'Custom Watermark'. Choose 'Picture Watermark', click 'Select Picture', and choose the 'Work Offline' option to browse and insert the image from your local computer.
Add Watermarks Seamlessly with WPS Office
Tired of encountering HTTP 400 connection errors and waiting for software bug fixes? WPS Office provides a lightweight, highly compatible alternative to Microsoft Word, allowing you to easily add custom picture or text watermarks without annoying connection glitches.
- 1. Open Document: Launch WPS Writer and open your document.
- 2. Navigate to Watermark: Click on the 'Insert' tab and select 'Watermark' from the ribbon.
- 3. Insert Custom Graphic: Click 'Insert Watermark', choose 'Picture Watermark', upload your local image, adjust the scaling, and click 'OK'.
Frequently Asked Questions
Why am I getting a 'Request Too Long' error in Word?
This HTTP 400 error is caused by a known software bug in Microsoft Word. It occurs when the application attempts to connect to Microsoft's servers for online pictures or watermark commands, but the request header exceeds server limits and gets rejected.
Are other features affected by this HTTP 400 error?
Yes, this bug can also trigger when you try to use 'Insert > Pictures > Online Pictures' or when you attempt to define a new bullet point using the online picture option.
Will Microsoft fix this watermark bug?
The Microsoft Word development team is aware of the issue and is currently investigating it. Because they have struggled to reproduce it consistently, there is no exact timeline for a patch, making the offline workaround necessary in the meantime.
Can I still use online pictures after applying the workaround?
No, the workaround temporarily disables experiences that download online content. To use online pictures again, you must go back to File > Options > General > Privacy Settings and re-enable Connected Experiences.
