I am facing a problem with the function SendAs Zimbra.
For example the case of a asssitante who need to send email with the address of his manager.
Under the webmail functions "send as" and "send behalf of" work perfectly well.
From outlook (2007 or 2010), only the "send behalf of" work, but impossible to do work "send as". I have an email directly to non-delivery of mail that tells me I do not have the rights to send as another person while the right is active and that fonctionnne from webmail.
Is this normal for Outlook? Is an Outlook security?
Thank you in advance for your help.
