Windows 10: Windows File Save / Save As Dialog Not Showing Drives

I've been noticing an issue in my Windows 10 PC. Currently on our enterprise Windows 10 version 1803 (build 17134.1006). I have Outlook on Office 365 version 1808 (build 10730.20344 click-to-run)


When I go to save files from an email, I get a file save dialog box that doesn't show any drives. As you can see in the image below, I have the folders on the right pane but nothing on the left.






i also have no way of choosing my OneDrive or OneDrive for Business or network share drives.


If i just open File Explorer, I do have these options:





Is this a Windows or an Office issue?

Open/Save Dialog not showing all folders/files

Hi Gary

In order to get a better idea of the problem, can you please provide a screenshot of a listing of those folders in Windows File Explorer and also in the Open/Save dialog, which shows folder that cannot be seen in that dialog . . .

 

Saves log files ?

You can either read the files in Windows or my preferred method is.....

Download CCcleaner from here...........

CCleaner Professional | Try the world’s most trusted PC cleaner, free!

You can then run cleaner, you will see the log files listed, then if you right click you can save as a text file and then have a read. You may also get an "error reporting" log listed seperatly.

 

Save Dialog Resize Problem


Ok, here's what I did. Using the registry key from hjschlicht, (HKEY_CURRENT_USER/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer/ComDlg32/CIDSizeMRU), Thanks for pointing me in the right direction, I found a list of registry keys labeled as follows;
Default
0 - 48
MRUListEx





Make a back up of this key before modifying anything.

I deleted all entries except; Default, 0 and MRUListEx.

This reset all of my dialog boxes. I then opened Photoshop CC (since I removed CS6 previously to try to solve the problem) and made a small image and then clicked on file>export>save for web.

The dialog box that COULD NOT be re-sized before was now reset to a more normal, if a bit small, sizing. I re-sized the window to my preferred size, 8 x 4 medium icons, and saved the test image.

I then returned to the registry editor and looked at the list. I now had a new entry labeled '42'. (can ya feel the irony there?)

Right clicking on entry 42 and modifying it shows the following;





I exported this key and then went back into Photoshop and intentionally re-sized the save for web dialog window to near full screen. This did not create a new key but modified the '42' key from before. I then exited Photoshop and double clicked on my saved '42' regedit key to import the data.

Launching Photoshop yet again, my 'save for web' dialog was back to normal.

I do not know if the 'save for web' dialog is the same on every windows 10 system or if CS6 will create additional entries, but it would appear that if you make a backup of this key while the window is at or smaller than the size you like, you can easily restore it if it becomes over enlarged again by double clicking and re-importing the back up key, without having to go through regedit again and drill down for it.

I repeated this process 3-4 times to make sure it always used the same key instead of creating a new one. This key is ONLY for the 'save for web' dialog box. Other 'save' or 'save as' menu items/methods create their own keys.

On the chance that other windows 10 installs use the same key label, I have attached mine here for download if desired.
