Exchange 2010 Full Access to mailbox not working.

Question

Hi Guys
Few changes were made to exchange so users can only have "send on behalf of" when using shared mailboxes.
for example : Sent from Bob Smith on behalf of [EmailAddress1]
need to grant full access, then use the client delegate (outlook 2010) and add them to that also.
even if you set permissions to none in Delegate the full access kicks in.
if you remove the users name from delegate (set with no permissions) full access is gone.
has anyone else come across this ?
ive been trolling the net the last 2 days and havernt found a thing . .
any help would be great.

Hi ITWizchch,
Try these methods to check what's happening and set the required access (i.e. SendOnBehalfOf without Full Access)
Check for individual user or all users having access on John's mailbox:
Get-MailboxPermission -Identity [email protected] | Format-List
Get-MailboxPermission -Identity [email protected] -User "Ayla"
Once permission is set you can use below to remove it:
Remove-MailboxPermission -Identity John -User 'Ayla' -AccessRights FullAccess -InheritanceType All
Set SendOnBehalf Permission:
Set-mailbox John -GrantSendOnBehalfto @{Add="Ayla"}
Set SendOnBehalf Permission:
Set-mailbox John -GrantSendOnBehalfto @{Remove="Ayla"}
NOTE:- When you modify a multivalued property, you must ensure that you append / remove the values accordingly , without Overwriting the existing list.
