Cannot open Office documents through mapped drives - Opens Office start screen

Question

Hi all,
So very strange issue here. (Windows 7 - Office2013 with Office365 subscription)
We have a user who reported that when they opened anything in Word or Excel etc, it simply does not open and instead goes to the Word (for example) start screen where it asks if you would like to start blank document etc.
Strange thing is, after some troubleshooting, I found that this issue only occurs when opening from the file server. Desktop is fine. Even stranger is that it only happens when opening the document via the mapped drives. When going through the full path
in explorer it works fine.
I have tried the below...
Office repair and clean re-install
Starting Word in safe mode - Recent docs that were opened from mapped drive do not work either
Adding users server credentials in Windows credentials manager (though not sure how to add for mapped drive - only for full path)
Disconnecting and re-adding mapped drives
Logging into another computer with this user works fine.
Logging in as another user on the laptop works fine too.
Thanks
Glen

Hi,
Since you have mentioned:
"Logging into another computer with this user works fine.
Logging in as another user on the laptop works fine too."
It's just an issue with the specific user on the specific computer, probably the Windows Profile has been corrupted.
The detailed steps to fix the corrupted user profile, please refer to this article below:

If your computer is on a domain:
Open Microsoft Management Console by clicking the Start button
, typing
mmc into the search box, and then pressing Enter.‌  If you're prompted
for an administrator password or confirmation, type the password or provide confirmation.
In the left pane of Microsoft Management Console, click Local Users and Groups.
If you don't see Local Users and Groups
If you don't see Local Users and Groups, it's probably because that snap-in hasn't been added to Microsoft Management Console. Follow these steps to install it:
In Microsoft Management Console, click the File menu, and then click
Add/Remove Snap-in.
Click  Local Users and Groups, and then click Add.
Click Local computer, click Finish, and then click
OK.
Click the Users folder.
Click the Action menu, and then click New User.
Type the appropriate information in the dialog box, and then click Create.
When you are finished creating user accounts, click Close.
Restart the PC.
Hope this helps.
