Can't save MS Office 2016 documents to "My Documents" folder

Upgraded to Windows 10 Creator's Update 15063 from previous build. Was ok for a while, then unable to save any word or excel documents to the "My Documents" folder. No error, just hangs and I have to kill the process. Not sure it was the update, but that was the only thing that changed since there wasn't any issue. I'm able to save to any other folder on the same drive or another drive.

I've done the Office repair AND the Online repair (basically a reinstall) with no luck.

Thanks in advance

open Excel under safe mode Excel /safe  or WinWord /safe and try to save any document into My documents folders
If that saved correctly therefore you need to disable same addins

Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

Clicking any of the "update options" pull down only take me to webpages about Office features. I'm not use 365.

Office Professional 2016
Version 1703 (Build 7967.2082 Click-to-run)

Make a new, test, Windows User Profile (Account). Log into the new Windows Account and test Office save ability in the new account.

No issue for me here on the newest Windows Version 1703 and Office 2016 (which was patched at the same time).
RickzzzAuthor Commented:
Also, I should note there are no updates for Office listed to uninstall in "Uninstall an Update", nor are there any available.
JohnBusiness Consultant (Owner)Commented:
Try a new Windows Account to test.

Same issue under another profile, hangs and have to kill process when I try to save in the location of my current profile's "My Documents". I can however save in that profile's "My Documents",
JohnBusiness Consultant (Owner)Commented:
That indicates that the existing Windows Profile is damaged and needs to be replaced.

under another profile, ...  I can ... save in that profile's "My Documents"  <-- I assume I read this correctly that in the new test Profile you can save documents in the new test My Documents.
RickzzzAuthor Commented:
Yes. But I couldn't, under that new profile, save to the "My Documents" folder of my current profile. It would hang in the same manner.
JohnBusiness Consultant (Owner)Commented:
But I couldn't, under that new profile, save to the "My Documents" folder of my current profile  <-- That is normal because of Windows security, So you do have a damaged (current) profile that needs to be replaced.
RickzzzAuthor Commented:
The new profile does have write access to that location. It's actually just another drive in the laptop (D:) where I store my documents ("moving" the documents location in properties).

Anyway, I'm on a domain. Would this still be the best way to accomplish?
JohnBusiness Consultant (Owner)Commented:
In the vast majority of cases, damaged profiles must be recreated
RickzzzAuthor Commented:
Deleted/Recreated profile. Same issue.

Which would seem to follow the issue persisted when I created a NEW profile earlier:
But I couldn't, under that new profile, save to the "My Documents" folder of my current profile

I'm just going to reinstall Windows.

Thanks for efforts.

You can either Repair Windows or back everything up and Reinstall Windows. Based on your most recent post that the newly created profile does not work, then now we must say that Windows itself is damaged.

Is My Document default location or redirected?
Fethi ABASSIWindows system administratorCommented:
Try command line: chkdsk /f /r /v
RickzzzAuthor Commented:
My Docs redirected to another partition.

Did the chkdsk thing too.

Reinstalled Windows, all good, as you might expect. The latest Creator build installer worked great. Had a few little issues to sort through with the previous build installer on this same laptop. None so far this time.

I'll 1/2 solution to both.

Thanks for your assistance.

Reinstalled Windows after no joy with troubleshooting.
JohnBusiness Consultant (Owner)Commented:
Thank you for your update and I was happy to help you resolve this.

Reinstalled a bunch of stuff over the weekend and the issue returned this morning.

Went through the process of turning on and off services and restarting over and over this time since a Windows reinstall wasn't going to fix it.
Turns out is was Malwarebytes v3.0.6 > Exploit Protection. Played with a number of those EP specific settings, but couldn't get the problem to resolve without turning "Exploit Protection" off.
JohnBusiness Consultant (Owner)Commented:
Try using Windows Defender instead of Malwarebytes.  The Creator 10 update seems to have caught some AV vendors flat-footed (including Symantec for me).
