Cannot forward mail when a secondary smtp e-mailaddress is selected


Some users have problems forwarding mails.
We have one mailbox the that has about 10 e-mailaddresses configured on it.
so all mails sent to,, come into 1 mailbox.

When the user creates a new mail and selects in the from field all the mails get forwarded.
When the user creates a new mail and selects in the from field the user gets the error:
"You do not have permission to send to this recipient.  For assistance, contact your system administrator."
The is not the primary SMTP address but a secondary.

This should work, how can we fix this or is there a fix from MS?

Unfortunately Exchange does not deal with sending from secondary addresses. As far as Exchange is concerned you can only have one from address and therefore won't let you send from the secondary addresses.

You need to have multiple mailboxes with permissions to send from those mailboxes with those additional addresses. There are ways to trick Exchange but I don't usually do this but try this from Kieran
