Exchange 2010/2013 allows you to create mailboxes in different locations, also called sites. Smarsh Hosted Services provides two possible mailbox locations: East Site and West Site. Please note that mailboxes cannot be moved from one location to another through CONTROL PANEL.
- Create an organizational unit (OU) and specify the desired Default Mailbox Location. The Default Mailbox Location setting determines the default site for all newly created mailboxes in this organizational unit.
- Navigate to Users > Organizational Units.
- Click Create New Organizational Unit button.
- Type the OU name.
- In Default Mailbox Location, select the desired site.
- Click Create New Organizational Unit
- Navigate to the Users page and click Create User.
- Select the Exchange checkbox. Enter the required user information.
- In the Organizational Unit box, select the desired OU.
- To create multiple users, click the Add another user link.
- Click Create.
To enable Exchange service for an existing user, select the Exchange checkbox next to the user on the Users page in CONTROL PANEL. The mailbox will be created in the same organizational unit where the user was created (see instructions above). You cannot move an existing user to a different location, even by changing the organizational unit.
For details about importing multiple users at once, read the Knowledge Base article on Mass User Import. When importing, you will be able to select an organizational unit if at least one OU has already been created. Otherwise, all users will be created in the default location, which you can view on the Get Started Here! page under the Advanced Exchange Settings link.
