The only ACLs we have set (allow) are these. Read Send As Read Exchange Information Read Exchange Personal Information Read Phone and Mail Options

I think it used to happen less frequently than is happening now though, with 2003 it was maybe a few times each quarter, now it seems to happen a couple times per month. Our Org is 2003 Domain/Forest Functional with Exchange 2010 SP3 (14.3.123.4) running on 2008 R2 SP1. Mail clients are Outlook 2007/2010/2013. We have several mail enabled Universal Security groups we use as distribution lists and the members of each group have an individual ACL for Send As permission. There are times when someone sends a message as the group address they receive a bounce back saying they don't have permissions to "send on behalf" of that address. I find that part very curious because they are using Send As, not send on behalf of. The process to send is always the same (enter the specific address in to the From message field) and most of the time it sends with no problems. I used to chalk this up to someone's auto complete cache being corrupted and just delete the entry but I'm not sure that's really the case. I noticed this morning when it happened to me (Outlook 2013) that the From field on the sent item displayed as "list-address "on behalf of" list-address", but then the one that went through successfully only shows "list-address" in the From field. I've checked the objects in AD and the Send on behalf option is unused. Why would Outlook, or Exchange do that? Any ideas on where to look next? Thanks, Neil
