Windows 10: Word and excel Documenets Marked as read only and cannot save

Hello,

I have new fun problem with Word and Excel documents that I have been editing for years (such as resumes) opening a "read only" doc and when I try to save to its original folder getting an error the drive is either full or that I do not have permissions to write to this folder (such as root C drive). I just now found out I can save to my C:\Downloads folder so I have a workaround. (thank goodness!!)

This problem also extends to any new word or excel doc I try to create and then try to save.
This problem DOES NOT extend to other office Apps and files such as Power Point as old docs do not open as read only can be edited and save as well new PP docs can also be saved to the very folders that Work and Excel are telling me are full or to which my ID does not have permissions.

The OS version I am using is Home Windows 10 and I am using Office 365 with the subscription valid through November.

Lastly I had an Windows update (1703) on July 18th which I suspect is the cause of this issue.

I was on the phone with MS support who was unable to remedy and has bumped me up to a level 2 appointment on Monday.

This morning I noticed my USERS drive had the "Read only" attribute under properties and thought I might have found the fix by removing that attribute. I was prompted to run this change as administrator I clicked continue which my ID is and is also my Windows Live id. The dialogue process box then logged it was removing the attribute from several gig of files and subfolders and at least briefly it seemed that I had stumbled onto the answer!

But alas when I open a new Windows explorer and click under properties the USERS folder shows that it still READ ONLY and so are all the user account folders and their subfolders.

I found some older remedies online but none have worked.
Has anyone else had this issue and resolved?
Any input would be welcome

I just got off the phone with MS Support and he had found the Bit Defender 2017 anti virus Software has these exact issues with certain Office 365 products. We removed the Bit Defender, restarted my PC and issue has been resolved.

I confirmed this issue on the Bit Defender Forums and it seems that when removed and replaced with 2018 Version the conflicts between the two products have been resolved.

So if anyone else has this problem with Office 365 and is also running BD 2017 this should resolve your issues

I am contacting BD support now.

Thank you for letting us know the answer to your issue, it will be helpful to future Google-ers of the same issue.
