Use the Exchange Management Shell to set up mail forwarding

5 de Dezembro de 2018 – 10:55

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.

Hyper-V Tips & tricks Utils

VMDK to VHDX

30 de Agosto de 2018 – 14:34

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

How to prevent internal email spoofing in an Exchange organization

12 de Julho de 2018 – 14:59

Ensuring email security might be one of the most important and most difficult tasks an administrator must face. Every day, servers process thousands of emails and controlling such a big mail flow is not easy. No wonder hackers focus on this channel when they plan attacks. They use various tricks to make users think that opening a suspicious attachment is a good idea.

One of the tricks they use is email spoofing.

Prevent Internal Spoofing in Exchange organization

What is email spoofing?

Email spoofing is a very popular attack method. The sender modifies message headers so that emails appear as sent from someone else. Hackers use it, for example, to impersonate employees of a company to obtain login credentials, personal data, or other confidential information. Two most common ways to protect your organization from external spoofing attacks are:

  • An SPF record – a list of IP addresses which are authorized to send emails from a domain.
  • DKIM check – an email authentication method. It enables you to sign and verify email messages using public and private keys. The public keys, published in the DNS records are used to verify if the message comes from the original sender. You cannot configure it on the Exchange Server natively – you require a plugin for SMTP gateway.

Both ways give good results when fighting with external spoofing. The problem starts when we come across internal spoofing when one employee tries to impersonate a colleague. It might be a joke, or to achieve some benefits – either way, it can sabotage a company in a number of ways:

  • Cause chaos,
  • Induce material damage,
  • Harm data integrity,
  • Damage the company reputation.
