Are you getting the error code: “The computer computer can’t verify the identity of the RD Gateway. It’s not safe to connect to servers that can’t be identified”? You most likely setup Remote Desktop Web Access (RDweb) with a self signed certificated.

The reason why you are getting this error is your machine doesn’t trust and can’t verify the identity of the RD Gateway.

To allow your machine to trust the RD Gateway and get RD Web Access working you will need to import the Cert from the website and put it into the “Trusted Root Certification Authorities” store

Use the Exchange Management Shell to set up mail forwarding

This example delivers email to the mailbox of Douglas Kohn and, at the same time, forwards all mail sent to Douglas Kohn to douglaskohn.parents@fineartschool.net.

Set-Mailbox -Identity "Douglas Kohn" -DeliverToMailboxAndForward $true -ForwardingSMTPAddress "douglaskohn.parents@fineartschool.net"  

 

This example forwards all email sent to the mailbox of Ken Sanchez, an employee of Contoso Suites, to one of his coworkers, pilarp@contoso.com.

 
Set-Mailbox -Identity "Ken Sanchez" -ForwardingSMTPAddress "pilarp@contoso.com"
 

For detailed syntax and parameter information, see Set-Mailbox.

 

Note:
-ForwardingsmtpAddress to multiple addresses Shell script

The parameter “ForwardingSmtpAddress” only allow to setup one SMTP address.
To work around this issue, you can setup the mailbox forwarding to a distribution group, you need to add the users you want to forward message to this distribution group.

VMDK to VHDX

Follow steps:

  • Download: http://www.microsoft.com/en-us/download/details.aspx?id=42497
  • Open Powershell as administrator and run Import-Module 'C:\Program Files\Microsoft Virtual Machine Converter\MvmcCmdlet.psd1'
  • And after ConvertTo-MvmcVirtualHardDisk -SourceLiteralPath
    d:\scratch\vmx\VM-disk1.vmdk -VhdType DynamicHardDisk -VhdFormat vhdx
    -destination c:\vm-disk1

If you counter following error:

ConvertTo-MvmcVirtualHardDisk : The entry 1 is not a supported disk database entry for the descriptor.

In my case it was entry 4

Follow these steps:

  1. download and extract dsfok tools
  2. use dsfo.exe "c:\temp\disk2.vmdk" 512 1024 descriptor1.txt to extract the descriptor
  3. edit the descriptor file in Notepad++: comment the above mentioned line (as I added the extra single character (#) I also deleted one NULL character from the end to keep the file size of 1024 bytes (not sure if this is needed).
  4. use dsfi.exe "c:\temp\disk2.vmdk" 512 1024 descriptor1.txt to inject the descriptor back into the VMDK
  5. repeat these steps for the other disk (my VM has two .vmdk files)
  6. reissue the ConvertTo-MvmcVirtualHardDisk command
