I save one word letter on my machine and tried to open it. I got the below error:
Word experienced an error
Try suggestions:
* check the file permissions
* Make sure there is sufficient free memory
* Open the file with the text recovery

Then I go to the properties of word document and in custom tab I changed any custom property value and then apply.

Then surprisingly word document opens perfectly.

It is not related to any specific custom property value but I think changing any value will set some permissions of the document.

Please let me know if any common settings are there in word doc which can i change and let the word letter open properly without error.

I do not want to set the custom properties of each and every document.
