A user in our business has reported that every word doc he has gives the same error when he tries to open, some docs are over 4 years old, some are only a week old.
The error happens wether he double clicks file, open file from within word - even with "open and repair" option.

error:
"The file XXXX cannot be opened because there are problems with the contents. Details - Microsoft office cannot open this file because some parts are missing or invalid"

click ok then:
"Word found unreadable content in XXXX. Do you want to recover the contents of this document? If you trust the source of this document, click Yes."

Hi,

What if you copy these Word files to another computer and then try to open them there?

From when is he/she facing this issue, did the user make any changes on the computer prior to the issue?

Which version of Word is he/she using? Please first try to rename the global template (Normal.dotm) and then verify result:

Go to %userprofile%\appdata\roaming\microsoft\templates, right-click Normal.dotm, and then click Rename. Type Normal.dotm.old, and then press ENTER.

Hope this helps.

Regards,
