Exchange 2010 send as

Ok, so I have a user account called sales. And that user account has two email address, sales@discountsales.com and sales@pricecuts.com.

The user account's primary SMTP address is sales@discountsales.com.

We send out email blasts to our customers from this address. We would also like to send out email blasts from the sales@pricecuts.com but it keeps returning the message that I don't have permission to send as this user.

Why can I send as one email address and not the other?

We've been doing this without any problems for the last 5 years. But last weekend we upgraded from exchange 2003 to exchange 2010 and now this doesn't work.

I've browsed over every nook and cranny of the Exchange Management Console and can't seem to figure this one out.

Any help would be appriciated.

That's a great idea.

The problem I'm having now is assigning send as permissions on the distro group. When I open EMC > Recipient Config > Distibution Groups. Look in the Mailflow settings tab on the properties window there is no delivery option selection to choose so I can't give send as permissions this way.

I went into ADUC and then gave myself send as permissions from the security tab for that group but I'm still getting the error that I don't have permission to send as this user. Any ideas?
I even tried giving send as permissions through powershell and it still doesn't send.

You are correct you need to add the Send As permissions from AD as this is an AD permission not Exchange. Also, this change takes time to replicate as well.

Have you tried to Send As using OWA? This should work immidately, rather than using Outlook. If you are using Outlook in cached mode then this could be slowing down the replication as cached mode does not update instantly.
Perfect! turning off cached Exchange mode fixed it. I didnt' realize that Outlook cached user permissions. thanks!
No splitting points?
Sorry, I thought you were the same guy.

Oh, I know the problem is closed but I still have another problem. I tried it using my account and it works because I'm an enterprise admin. But when I use a different account that isn't an enterprise admin it doesn't work.

What permission does the enterprise admin have that I can add for a user without giving them enterprise admin rights? I've given them full control over the distro group and still nothing.
