Microsoft Exchange Server, including Office 365, itself can function as source or target system, as well. This article deals with connecting to and handling Exchange servers. Exchange servers can contain various types of archived items. Email Migrator capabilities regarding item migration and feature handling in respect to Exchange server are summarized in the table below.
The user under which the migration from Exchange server runs must have full permissions to the migrated mailboxes. The instructions on how to assign these permissions to the migration user does not belong to the scope of this article, but they can be found in Microsoft technet articles, such as Manage Full Access Permissions.
To establish the connection to Exchange Server as source/target, click on the Connection tab > Connect to Exchange Server button.
This will open the Connect to Exchange dialog, which contains the following fields:
a. Exchange Server 2003 and 2007 (without service pack) support only Messaging Application Programming Interface (MAPI) connection. Therefore, if Outlook is not installed on the Archive Migration machine or Outlook bitness does not match the machine bitness, these two options - Exchange 2003 and Exchange 2007 - are disabled.
b. Additionally, Exchange Server 2003 requires Outlook 2010 or older. The connection will not work with newer Outlook versions.
o Exchange Web Services (EWS) - This type of connection is available and recommended for Exchange 2007 (SP1 or higher) and later.
NOTE: EWS is the recommended connection type. The second one, Messaging Application Programming Interface (MAPI), should be used only for Exchange Server 2003. EWS requires that Application Impersonation role is assigned to migrating user.
§ Use https - Uncheck this option if EWS is running without SSL (https).
§ Use Fast Transfer - For Exchange Server 2010 SP1 and higher, it is possible to use Microsoft Fast Transfer protocol for connecting to Exchange. Since it is faster, it's the recommended option. If any archive is used as a source connector at the migration, Fast Transfer is not applicable.
NOTE: Should folder or PST file be an intended migration target, the Use Fast Transfer option must be unchecked.
o Messaging Application Programming Interface (MAPI) - This type of connection is available for Exchange 2003 SP2 and later. But, for Exchange Server versions above Exchange 2003 SP2, this is not the preferred option. If the logged on user does not have full access permissions to the selected mailbox, the "Error in IMsgStore.OpenEntry: MAPI_E_NOT_FOUND" message appears.
ATTENTION: To use this type of connection:
Ø Outlook is necessary on the Email Migrator machine and the bitness of Outlook and OS must be the same.
Ø Connection to Office 365 is only possible when Outlook 2013/2016 is installed on the Email Migrator machine.
Ø Connection to Exchange Server 2003 is only possible when Outlook 2010 or older is installed on the Email Migrator machine.
Ø Email Migrator must be in the same domain as the Exchange Server (does not apply for Office 365).
Ø Migrating user must have full access permissions to migrated mailboxes.
o Kerberos - Recommended when the Exchange Server is in the same domain as Email Migrator. For this type of authentication, the Exchange server must be specified by server name (not the IP address).
o Basic - Recommended when the Exchange server is in a different domain as Email Migrator. The basic authentication must be enabled for PowerShell Web Service on the target Exchange server.
o Default - Will try to use Kerberos or Negotiate authentication mechanism.
o NegotiateWithImplicitCredential - Windows authentication must be enabled for PowerShell Web Service on the Exchange server.
NOTE: Other authentication types can be used at an administrator's convenience.
To view/list the mailboxes to which the user has access rights, the specified user must be a member of Organization Management group in Active Directory (AD). If he is not, he will see only his own mailbox. To add the user to this group:
1. Go to the AD machine.
2. Click Start > Administrative Tools > Active Directory Users and Computers.
3. Expand the domain and select Users.
4. Right-click on the user and select Properties.
5. On the Member Of tab > add the Organization Management group.
6. Click OK to close the windows.
NOTE: By default, the administrator account should be a member of the Organization Management group.
After all of the desired connection options have been set, click OK to establish the connection. If Email Migrator is successful in making the connection, a new node appears in the Explorer View. You can expand this node and navigate user mailboxes.
NOTE: After updating Email Migrator to a newer version, some Exchange connections may disappear from the list of connections and it may be necessary to re-establish them.
