The email address of the mail-enabled user must match the WindowsEmailAddress property for the corresponding on-premises mailbox.Ī password has to have a minimum length of eight characters, and satisfy any password restrictions that are applied to your Microsoft 365 or Office 365 organization. Mail-enabled users are created in Microsoft 365 or Office 365 as a result of directory synchronization or another provisioning process. Specifies the email address for the mail-enabled user (or a mailbox if you're retrying the migration) in Microsoft 365 or Office 365 that corresponds to the on-premises user mailbox that will be migrated. The following table describes the supported attributes for a CSV file for a staged Exchange migration. For more information about staged Exchange migrations, see What you need to know about a staged email migration to Microsoft 365 or Office 365. To migrate more than 2,000 mailboxes, you have to create additional CSV files and then use each one to create a new migration batch. However, the CSV file for a migration batch can contain a maximum of 2,000 rows. There isn't a limit for the number of mailboxes that you can migrate to the cloud using a staged Exchange migration. You have to use a CSV file to identify the group of users for a migration batch when you want to use a staged Exchange migration to migrate Exchange 2003 and Exchange 2007 on-premises mailboxes to Microsoft 365 or Office 365. Target environment denotes the location that the mailbox will be migrated to or the database that the mailbox will be moved to.Īll mailboxes that are specified in the CSV file will be migrated, even if they are outside of the RBAC scope (for example, an OU) that gives the admin permissions to migrate mailboxes. In the following sections, source environment denotes the current location of a user mailbox or a database. For more information and examples, see the section Attribute values in the CSV file override the values for the migration batch. However, make sure that you include the comma to separate the null value from the next attribute.Īttribute values in the CSV file override the value of the corresponding parameter when that same parameter is used when creating a migration batch with the EAC or Exchange Online PowerShell. If the attribute value for a particular record is null, don't type anything for that attribute. Each attribute value is separated by a comma. The attributes in each individual user row must be in the same order as the attribute names in the header row. Each row under the header row represents an individual user and supplies the information required for the migration. Each attribute name is separated by a comma. The first row, or header row, of a CSV file used for migrating users lists the names of the attributes, or fields, specified on the rows that follow. Supported attributes for CSV files for bulk moves or migrations A cutover Exchange migration doesn't support using a CSV file because all on-premises user mailboxes are migrated to Microsoft 365 or Office 365 in a single batch.
