Power shell Cmd to create Forward inbox rule for Email Router – ForwardAsAttachmentTo
Below Power shell cmd will come handy if you want to quickly add forward inbox rule for multiple mailbox in Email Router. If you have 500 mailbox to deploy this rule it will take just 10 seconds to execute compared to 30 minutes in rule deployment wizard
Command :
New-InboxRule -name “ToCRM” -mailbox SourceMailboxEmail -ForwardAsAttachmentTo ForwardmailboxEMail
“ToCRM” – Rule Name just for identification
“SourceMailboxEmail” – Actualmailbox which will forward email as an attachment to the forward mailbox eg: chitra@microsoft.com
“ForwardmailboxEMail” – forward mailbox emaill address where all the emails forwarded ef: emailrouter@microsoft.com
You could use Rule deployment wizard but it takes lot of time also if you have more than 25 mailbox and want to deploy rule for selected mailbox it gets to time consuming process.
