I want to send from a shared mailbox but do not want the email to se "Send on Behalf of"

I created an ordinary user mailbox on my Exchange 2007 server. I then used the SHELL command to make it a shared mailbox. I gave a user FULL ACCESS permission, then I went to MAIL FLOW SETTINGS and granted SEND on behalf of permission. I later realized that I want to user to be able to send as the shared mailbox and do not want "on behalf of" or the user's name involved, I just want it to appear to come from the shared mailbox. I right clicked the mailbox and gave the users SEND AS permissions and took her out of the Send on behalf of, but I still get the same message. How can I get a user to send from the shared mailbox with out "on behalf of"??

Oh, if it's still showing Send of behalf after you remove the permission. It's because of an interval which the Information Store refreshes settings, and it's by default two hours.  Permissions changes can take that long to take effect.
Remove the "send on behalf of" permission
Give that person the "send as" permission
Click View in the menu and choose From Field

 This will allow users to send mail from a mailbox as if they were that user.

You can do so by login to the shared mailbox using OWA. https://webmail/sharedmailboxsmtpaddress.
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

You can check this relevant thread discussed earlier : modify or remove the "on behalf of" on group mailbox using outlook 2007

ok, I have the SEND AS working the way I want it to. It seems I just had to remove the "SEND on Behalf of" and let it sit over night. In the morning everything was working ok, but today I noticed that all items she sends as the shared mailbox are going to her personal sent items and not the sent items of the shared mailbox. Is there a way to get sent items to go directly to the sent items of the shared mailbox? We are using Outlook 2007 and Exchange 2007

That is the default behavior of outlook where emails are saved in the primary outlook profile mailbox. You need to modify a registry key on  the machine running outlook to get them saved in shared mailbox sent items.

1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following registry subkey:
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type DelegateSentItemsStyle, and then press ENTER.
5. Right-click DelegateSentItemsStyle and then click Modify.
6. In the Value data box, type 1, and then click OK.
7. Exit Registry Editor.
