We will discuss these post-migration tasks now:

  1. Assigning licenses to new users in Office 365 –
  2. It is required to assign licenses to the users in Office 365; otherwise, mailboxes get disabled after the grace period of 30 days. Licenses can be assigned to each user one by one (if using different license types) or in bulk (with the same type). Let us see how to assign the license to Office 365 users.

    1. Open Office 365 Admin Center. Go to the Active Users page.
    2. Select the user for assigning the license.
    3. In the Product Licenses option, click Edit on the rightmost side.
    4. Select your Location and toggle the license to ON from OFF (against the user name). By default, all licenses are turned ON. Toggle OFF the licenses in the list that you don’t want to assign.
    5. Finally, click Save to complete the process.
    6. Similarly, you can assign licenses to other users as well.

  3. Creating Autodiscover DNS record (connecting new Office 365 mailboxes to Outlook and other clients)
  4. Configuring a new Autodiscover DNS record for the Office 365 organization helps users connect their Office 365 mailboxes with Outlook and mobile clients. The new Autodiscover DNS record should have the same namespace as the one using for Office 365 organization. You can create DNS records for Office 365 when you manage your DNS records.

    Note: In Exchange 2013, Exchange 2010, and Exchange 2007, the administrator should set

    Set-ClientAccessServer AutodiscoverInternalConnectionURI to Null.

  5. Decommissioning On-premises Exchange Server –
  6. Once you are sure that all emails are routed to your Office 365 and don’t want to keep Exchange on-premises any longer, you can decommission your on-premises Exchange Server. In simple words, uninstall or remove your on-premises Exchange Server from the organization.
