    I cannot open Microsoft office files in my Win10Pro guest when sharing folders with the host.

    If I isolate the guest from the host, then I can open a locally saved file no problem.

    Turn on folder sharing and reboot. Now I cannot open any Office files - even files that are stored locally on the guest.

    This is HIGHLY repeatable and is true even after doing the following:

    1) Fresh install of Win10Pro from bootable media. Activation using my Microsoft Account
    2) Fresh install of Office 365 (About says - Office 365 MSO (16.0.12228.20100) 32-bit)
    3) Fresh install of Parallels Tools.
    Upon completing all of these steps, I can create, save, open, reopen and work with any Office file stored on the local (VM) hard drive.
    But as soon as I turn off Guest Isolation, the ability to open those local files goes away.
    Can't seem to load images to this forum software - but I can provide screenshots of the file in a folder on my C drive and then the error that Excel throws when I try to open that file.

    The error says "Microsoft Excel cannot access this file 'C:\Testing Docs\Book1.xlsx'. There are several possible reasons:...

    All other file types are can be opened through the Host/Guest bridge. I can save a file on my desktop on Guest and the file shows up on the Desktop on Host.

    Recap: I can open Office documents when I isolate the guest and the host. I cannot open Office docs (but can open every other file type) when the guest and host share desktop and documents.

    This is related to using SymLinks for Documents and Desktop. I currently symlink these folders to a BOX SYNC folder so that I continuously backup these folders.

    I found a (kludgy) workaround...

    1) Under the VM configuration OPTIONS | SHARING - Uncheck "Share Mac user folders with Windows" but leave SHARE FOLDERS set to HOME Only or All Disk.
    2) In Windows 10, right click on each of the Desktop, Documents and Downloads folders (assuming those are what you want to share) and select PROPERTIES | LOCATION. On that tab select MOVE and use the network location (not the mapped drive letter) for your folders on the Host side. For example, on my machine:
    Guest Desktop -> \\Mac\Home\Box Sync\BELK\Desktop
    Guest Documents -> \\Mac\Home\Box Sync\BELK\Documents
    Guest Download -> \\Mac\Home\Downloads
    (PS - assuming you were sharing before, don't copy the files from Old to New - since the source of truth is the Host.)​

    This seems to work OK - though login is a bit slower since Windows is waiting for these resources to become available before it completes the login process (presumably waiting for Parallel Tools to map \\Mac\Home )

    I've wasted too much time on this - but I'm fairly certain I did NOT need this work-around on Win7 and Parallels 13 (which was what I was using before a few weeks ago. Bit the bullet on upgrading to Win10 and decided it was probably time to move up on Parallels - but questioning both decisions at this point...)

    I'm no software engineer so I can't explain why Parallels / Parallels Tools cannot follow SYMLINKS, but a search of the forums seems to show this has been an ongoing issue (though again, I'm 99% sure I did NOT have this issue with Win7/Parallels 13 using the builtin Desktop and Documents sharing along with Office 16 installed on Parallels.)
