Install Exchange Mailbox servers using the Setup wizard
Before you install an Exchange Server 2016 or Exchange Server 2019 Mailbox server, verify the following prerequisites:
The target server must be a member of an Active Directory domain.
The account that you use to install Exchange requires the following permissions*:
Enterprise Admins group membership: Required if this is the first Exchange server in the organization.
Exchange Organization Management role group membership: Required if you've already prepared the Active Directory domain that will contain the Exchange server, or if other Exchange servers already exist in the organization.
* Members of the Delegated Setup role group can install Exchange on servers that have already been provisioned in Active Directory by an Exchange administrator. For more information, see Delegate the installation of Exchange servers.
Verify that you've read the release notes at Release notes for Exchange Server.
For more information about planning and deploying Exchange, see Planning and deployment for Exchange Server.

If this is the first Exchange 2016 or Exchange 2019 server in your organization and you haven't already done the steps in Prepare Active Directory and domains for Exchange, you arrive on the Exchange Organization page. On this page, configure the following settings:
Specify the name for this Exchange organization: The default value is First Organization, but you typically use the company name for this value. The organization name is used internally by Exchange, isn't typically seen by users, doesn't affect the functionality of Exchange, and doesn't determine what you can use for email addresses.
The organization name can't contain more than 64 characters, and can't be blank.
Valid characters are A to Z, a to z, 0 to 9, hyphen or dash (-), and space, but leading or trailing spaces aren't allowed.
You can't change the organization name after it's set.
