Forward email rule as the name implies, enable to forward automatically each email that sent to a particular mailbox to an additional email address.
The “Destination recipient” (E-mail address) could be “internal Mailbox” meaning a recipient from our organization or external recipient, meaning – recipient doesn’t belong to the organization (there is a different PowerShell Parameter for each of the options).
An additional parameter is an option of leaving a copy of the email in the source recipient mailbox or just forward the email message.

Running PowerShell commands in Office 365 based environment
To be able to run the PowerShell commands specified in the current article, you will need to create a remote PowerShell with Azure Active Directory or Exchange Online. In case that you need help with the process of creating a Remote PowerShell session, you can use the links on the bottom of the Article.
In this article, we will demonstrate a couple of scenarios for Mail Forwarding:
- Mail forwarding to an internal recipient: John and Suzan are recipients who belong to the office 365 domain names: o365info.com
- Mail forwarding to External recipient: John wants to forward each mail that he gets to an external email address: [email protected]
- Additional scenarios are: Mail Forwarding in Bulk mode – the option of forwarding email to a destination email address for all the office 365 users and a nice trick of email forwarding that will implement for external contact object.

Great article which makes things easy.
But what is the difference between -ForwardingAddress and -ForwardingSmtpAddress ???
-ForwardingAddress (internal; within organtization), -ForwardingSmtpAddress (external; forward to an email address outside of your organization)
Forward Email to internal Recipient & save local copy (Default)
Is not the default setting in my office365 config.
The default is Forward Email to internal Recipient & DONT save local copy
So the command will be Set-Mailbox -Identity -ForwardingAddress -DeliverToMailboxAndForward $true
this is very great and another way to get anonymous email for everyone and your primary email id will remain hidden but you will receive emails on your primary email ID. Its very great and just amazing. make anonymous email
“Forward Email to External Recipient & DONT save local copy” => Does this really work? In our case we failed with tests using ForwardingsmtpAddress and what I could read in other discussions our experience was confirmed.
Very helpful thank you so much for sharing.

Thanks to the comments above this is the command that I found to work for “Forwarding Email to External Recipient & save local copy | import from CSV File |Scenario 2”:
Import-CSV “C:\Temp\Users.csv” | % { $_.Condition = [bool]($_.Condition -as [int]); $_ } | ForEach {Set-Mailbox -Identity $_.mailbox -ForwardingSmtpAddress $_.forwardto -Delivertomailboxandforward $TRUE}
Can someone help me with a script to Forward Email to External Recipient & DONT SAVE local copy | import from CSV File
How come -ForwardingSMTPAddress should be used to forward to external email addresses, but the script in section 4.4 “Forward Email to External Recipient & save local copy | import from CSV File” uses -ForwardingAddress
Import-CSV “C:\Temp\Users.csv” | % { $_.Condition = [bool]($_.Condition -as [int]); $_ } | ForEach {Set-Mailbox -Identity $_.mailbox -ForwardingAddress $_.forwardto -Delivertomailboxandforward $_.Condition}
Is this just an error in the script? Or is there a reason for this?
Thank you so much, I used “2.2 – Find all users with Forwarding Address is set to Internal Recipient” to find an old mailbox that was causing problems for us! Very nice resource you have with this page.
Oh my goodness! Amazing article dude! Many thanks, However I am going through issues with your RSS.
I don’t understand why I cannot join it. Is there anybody else getting identical RSS problems?
Anyone that knows the solution will you kindly respond? Thanx!!
Great Article. Is there a way to turn on forwarding for a mailbox and it will stop forwarding after 60 days?
I actually adore your post. I read your site pretty regularly and you are always coming out with some
great items. I shared this on my FB and my followers only loved it.
Keep up the good work!
Thank you so so much!
