you do not have permission to open this mailbox - Exchange 2007 RRS feed

  • Hola,

    I'm getting error to open OWA "You do not have permission to open this mailbox."

    My current environment is , All roles in 1 box and a Domain Controller in the same server, I call this box Domain+Exchange Server.

    I created a different server for CAS/HUB and another server for Mailbox.

    All users in Domain+Exchange Server. When I create a user and move it to the new Mailbox Server, I will get this error on OWA.

    However I am able to login to OWA if I move the user to the Domain+Exchange Server.

    I am planning to demote the Domain+Exchange Server.

    Can anyone pls help.

  • Hi,

    Can you login into a user who is in new mailbox server??

    dont check the migrated user, if not create a new user in that server and try to login that user from owa.

  • Hi,

    I've tried tht but it doesn't work. I created few users in the new mailbox server and unable to login. Old users from old server are able to login.

  • Have you checked in Outlook? for both migrated user and existing user.

  • I have made comparison of permissions between users that could and could not access the OWA and Outlook.

    Please refer below for more information.

    Permissions for user in New Mailbox Server that could not access OWA:

    Permissions for user in Old Mailbox Server that could access to OWA:
