Question

Hello,

I have the problem that I cannot check a manifest file (.xml). I keep getting the error message marked. Do you have any tips for me?

Regards

The error "Fehler bei der Überprüfung der Manifestdatei" means there's an issue with validating the manifest file. Here’s what I would check to fix it:

Validate the XML – I’d run the manifest through the Office Manifest Validator to check for any formatting issues.

Check Required Fields – I’d make sure all mandatory fields like <Id>, <Version>, <ProviderName>, and <DefaultLocale> are correctly filled.

Correct Encoding – The XML file should be saved in UTF-8 without BOM.

Verify URLs – If the manifest includes external URLs, I’d check that they are correct, accessible, and use HTTPS.

Use Edge or Internet Explorer – Some versions of Office may have issues with certain manifests, so I’d try testing in different browsers.
