Can't send as in Exchange 2007

I have a shared mailbox set up with 2 users having full access rights. If I query the mailbox through PowerShell it says full access
[PS] C:\>get-mailbox admin | get-mailboxpermission -user kristen

Identity                           User                                AccessRights      IsInherited Deny
--------                            ----                                  ------------            -----------   ----
company.local/MyBusi... COMPANY\Kristen         {FullAccess}        False        False
However if I use theExchange GUI to manage full mailbox rights I get an error:
Some Controls are not Valid
- You have not made any changes to the list of security principals that are granted permissions

And the most important issue is that I cannot send as the user admin from Outlook. i get an error message email that says:
You are not allowed to send this message because you are trying to send on behalf of another sender without permission to do so. Please verify that you are sending on behalf of the correct sender, or ask your system administrator to help you get the required permission.

and
Diagnostic information for administrators:

Generating server:

/O=FIRST ORGANIZATION/OU=EXCHANGE ADMINISTRATIVE GROUP (FYDIBOHF23SPDLT)/CN=RECIPIENTS/CN=Dwight
#MSEXCH:MSExchangeIS:/DC=local/DC=companyepic:COMPANYSERVER[578:0x000004DC:0x0000001D] #EX#

How do i allow this user to send as the other user?

Full Access does not give you Send As permissions. They are separate. You need to grant both to the user account.

Does it allow another user to be set the relevant permissions?

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

Yes, I can use different mailboxes to add send as permissions and I can add myself to this email address with send as permissions

That would tend to indicate that specific user account has the problem.
Ensure permission inheritance is set correctly on the account through ADUC. You may also want to remove the Full Mailbox and Send As permission if they are listed. Wait at least two hours for the change to take full effect before attempting to set it again.
