When deploying software deployment via group policy permissons must be set so that the computer account has read permission to the install files.
To check this, open Computer Management and open Shared Folders.
Right click the deployment share and select Properties
Domain computers at a minimum should have read. In this example, I have Everyone as read.
Open Windows Explorer and navigate to the deployment folder. Right click the deployment folder
and select Properties
On the Security tab, you can see i have added Domain Computers as Read & execute, list
folder contents, and Read.
This will allow the computer accounts to access the softwaredeployment share.
To give a user full access to another users mailbox in Exchange 2010, follow these steps:
Open the Exchange Management Console
Click Yes on the User Account Control Dialog if it appears
On the left hand side of the screen, navigate to Microsoft Exchange –> Microsoft Exchange On-Premises –> Recipient Configuration
Right Click on the user’s mailbox you wish to give access to, and select Manage Full Access Permission…
Select the Name of the user you wish to give access to, and click OK
You can also accomplish this by using Powershell. In this example, Andrew will be given full access to Craig’s mailbox:
Add-MailboxPermission -Identity Craig -User Andrew -AccessRights FullAccess
You can also use groups. In the example below, the group called Sales Users will be given full access to Craig’s mailbox:
Add-MailboxPermission -Identity Craig -User “Sales Users” -AccessRights FullAccess
