Hi When i try to grant a user lets bas full access to mailbox mirjam it doesn''t work. In powershell i give the following command: [PS] C:\Windows\system32>Get-Mailbox -Identity "mirjam" | Add-MailboxPermission -User "bas" -AccessRights fullaccess WARNING: The appropriate access control entry is already present on the object "CN=Mirjam xxxxxxxx,OU=Gebruikers,OU=xxxxx,DC=xxxxxxxxx,DC=local" for account "xxxxxxxx\bas". Identity User AccessRights IsInherited Deny -------- ---- ------------ ----------- ---- xxxxxxxxxxx.local/... xxxxxxxxxxx\bas {FullAccess} False False But when i try to open the mailbox in outlook i see this (sorry its in dutch) it says can''t open set of folders Microsoft exchange is not availebel. there is a problem with the newtwork or ....... With kind regards, Bas van den Dikkenberg

Just be patience, it may take bit time for DCs to replicate and see the changes you have done. For hint pay attention to DC your Exchange Server is talking too, also the DC the outlook client is talking too, if they are not the same Domain controllers. Perhaps they have not communicate the changes been made ? Also I would try o configure the profile you are using from another PC on different network and try to see if you can get there good luck ocd

Hello, From your command output, it seems you have gave bas fullaccess permission on mailbox mirjam. I suggest you go to test in OWA: If bas can access mirjam's mailbox in OWA, this means the permission is working well, you can change Outlook to online mode or recreate Outlook profile to have a try. If bas still cannot access mirjam's mailbox in OWA, run this command get-mailboxpermission to check the permission on mirjam.

When i open just 1 folder in outlook this works. But why can't i open the entiere mailboxWith kind regards, Bas van den Dikkenberg

If you use other user to access the mailbox, will this issue occur? Judge from the error information, this is not a permission error, so I suggest you use another user (who also have full access permission) to have a try.
