A family of Microsoft word processing software products for creating web, email, and print documents.
This feature causes so many issues.
I've had code in place running for 15 to 20 years that has always worked, and now it's suddenly broken. For example, if there is a read only file in a location, and you try to create a new document using the Documents.Add command, you get a runtime error 5097. This also happens with just some documents in the Workgroup templates location. Move the exact same files to another directory and it works. Remove the read only attribute from the file and it works. It doesn't make sense when you are creating a new document from an existing file. This doesn't happen before built 2210 of Word where this feature magically appeared.
We sell a VSTO addin for Word which this feature conflicts with. It cannot detect the document is suddenly read only. It just fails (we trap the error, so the user doesn't see anything - but to the user nothing is working - the document no longer updates) We check for the Document.ReadOnly attribute - but this doesn't change with this setting. There is no way to detect if this setting is on or off. I cannot find any property or documentation to support it.
If you use VBA to write to the document body, or the selection range, you get different error messages. One says the document is protected - but you check the Document.ProtectionType and it returns wdNoProtection.
I'm getting calls logged daily because of this issue affecting our products, custom solutions and macros I have written for numerous clients over more than 20 years. I just had two more come in as I typed this response. I've logged multiple calls with Microsoft, but they keep closing the calls saying it's a developer issue and they can't help.
