First, you need to create an account in Office 365. You will need a domain-username account with administrative privileges. Next, you will create an endpoint for migration. This endpoint will be used to test connectivity between the on-premises Exchange server and Office 365. Ensure that the email account you choose has the appropriate permissions for your mailboxes.
After creating your migration account, click Start Migration. Once you have selected the migration plan, follow the steps provided by the wizard. The migration process will take a few minutes. During this time, you will need to assign licenses to mailboxes that are currently in your on-premises environment. After a grace period, mailboxes will be disabled until they are assigned a license.
Ensure that the on-premises Exchange organization has a primary domain name that can be accepted by Microsoft 365 or Office 365. You will need to migrate all existing users’ mailboxes to your new organization. Once you have the mailboxes migrated, you’ll have to assign licenses to them. The process will be easier if you prepare your server properly and export your data first.
Once the migration is complete, click Finish. You will be prompted to enter the FQDN of your physical Exchange email server and the RPC proxy server. Make sure to enter the hostname of your source server, or the FQDN of your Exchange virtual machine. Then, choose the migration endpoint, and leave the rest of the fields blank. Once the migration is complete, you should receive an email with the status of your mailboxes.
In part one, you will need to verify the primary domain name of your on-premises Exchange organization to Office 365. You will need to export your Exchange mailboxes to a CSV file. After completing the migration, you will need to upload the CSV file to the Office 365 Exchange Admin Center. Once you’ve uploaded the file, the process will be complete.
Once you’ve completed the migration, you will need to migrate mailboxes to your new Exchange 365 account. This will require you to assign licenses to your mailboxes. You will also need to make sure that you have sufficient bandwidth and that all your employees can access your Exchange e-mail. You can then migrate your Exchange organisation to Office 365. The migration will be completed in two parts.
Before completing the migration, you must verify the primary domain name of your on-premises Exchange organization with the Office 365 organization. Select the endpoint for migration. Once the migration has completed successfully, you will see a pop-up window asking for your confirmation. You can then migrate the rest of your mailboxes by selecting your recipients. Then, you’ll need to migrate your contacts to the new organization.
Before completing the migration, you must verify the primary domain name. You can also migrate your resource mailboxes to Office 365. You can do this using Cutover and Staged Migration. When you’ve verified the domain name, you can complete the migration process. Then, you can migrate all your mailboxes to the new organization. After completing the migration, you can change the recipient type.
Before transferring your users and mailboxes to the new environment, you should clean up your Exchange servers and the underlying data. Delete old distribution lists, and mailboxes that are no longer in use. If you’ve used Office 365 for more than three years, you might want to consider moving your users to the new system. If you’re using an Exchange on-premises server, you’ll need to work with the HR department to clean up this database.
Before you migrate your mailboxes, you should first notify your users that they are moving to Office 365. You will need to make sure that all users are using their new email addresses and that they haven’t switched to another mail service. By enabling Hybrid mode, you can also migrate on-premises users to Office 365. But you’ll need to set up on-premises servers to get your data out of the old server.
