Hi,

I am having a real issue with the following situation: we had a user ( X ) who was a delegate on someone else's ( Y ) mailbox. However, when sending messages, the user X could send a message as Y, but without the 'on behalf of' option, but straight as that user - as if it had Send As permission on Y mailbox.

I have checked Y mailbox in AD, both in Security and Advanced Options, and did not find anything related to user X having Send As permission.

I have also checked all the groups that X is part of, none of them has Send As permission.

Also, user X does not have Full Mailbox Access on user Y mailbox.

The situation above stopped when I removed user X from the user Y account properties in Ad, from the Exchange General > Delivery Options > Send on Behalf of section.

So it looks to me that the delegate Send on Behalf Of permission has been replaced somehow with the Send As permission.

Has anyone experienced this situation? And does anyone know how it could be resolved?

Ioana, are you still having this issue, or is it resolved.

There should be no way for a mailbox owner to grant "Send as" permissions from within the Outlook client.

The Tools, Options, Delegate Access wizard assigns Send-on-behalf-of rights by populating AD attributes on behalf of the mailbox onwer for the owner and the delegates, but Send-as involves a change on the security tab of the AD object in AD Users and Computers.

If you are still having the problem I'd be interested in asking a few questions, if not don't worry about it. It's an area I'm starting to get interested in, and your sitution is one I've seen before.

I'm sure there is a technical reason burried in a Microsoft Technet article somewhere, where "Mailbox Owner" at the top mailbox folder level supersede send-on-behalf-of rights or something, but I'd love to work it out...
