Granting Calendar Access via Exchange Control Panel (ECP)

Ex: Add-MailboxFolderPermission -identity "Managingdirector:\Calendar" -user "personalassistant" -AccessRights Reviewer
 
To change permissions on a Calendar item, type the following command:
 
This command will grant Calendar access, with level reviewer to his Personal Assitant. You can use Editor instead of Reviewer for more access.
 
If Managing director had PA in the past, you may want to remove that access. To that you can use the following command:
 
Ex: Remove-MailboxFolderPermission -identity "ManagingDirector:\Calendar" -user "oldPA"

Desktop Wallpaper Group Policy doesn't work for Win 10 clients: workaround

 
Windows 10 does funky things with wallpapers. It likes to make a cached copy in  %appdata%\roaming\microsoft\windows\themes\cachedfiles
and it will sometimes make a copy under  %AppData%\roaming\Microsoft\Windows\Themes\TranscodedWallpaper.jpg as well.
 
There is different behavior on Windows 7 and Windows 10 on desktop wallpaper. In Windows 7, when we log into the system, the cached wallpaper file will re-generated automatically.

But in Windows 10, if the wallpaper path didn’t change, the cached wallpaper will not re-generate.

After I deleted below file and log off/log on I can see the desktop wallpaper automatically changed on Windows 10.
 
%USERPROFILE%\AppData\Roaming\Microsoft\Windows\Themes\TranscodedWallpaper
So I applied this deletion operation to the domain controller as a log off  script, the script which is as below.
I created a .bat file and the content is:
del %USERPROFILE%\AppData\Roaming\Microsoft\Windows\Themes\TranscodedWallpaper
