Hi All
i am using Exchange 2016 hybrid environment. i have a shared mailbox and i have a requirement to forward the received emails which has pdf as an attachment from this shared mailbox to external email. I have created the below transport rule and user has setup the forwarder it is working fine, but zip files are also getting forwarded to external email, the zip files have pdf files what changes do i need to make to stop zip files getting forwarded to external email. if the zip file has excel file or text file those emails are not getting forwarded only zip files which have pdf as attachment are getting forwarded, pdf +excel those are also getting forwarded.
If the message...
Is sent to 'sharedmailbox@contoso.com'
and has an attachment file name that matches these text patterns: '.pdf'
Do the following...
set message header 'ApplicationHeader' with the value '1'
OutlookRule
Message Header includes: ApplicationHeader
Has Attachment
Forward to user@externalemail.com
