From Exchange to Microsoft 365 Migration Checklist

1. Check your Exchange Server version: Make sure your Exchange Server version is supported for migration to Exchange Online. You will have to upgrade your version to be able to perform the migration.
2. Prepare your Exchange Server: Get the hybrid deployment configured and make sure updates and service packs are fully installed. See the Exchange to Office 365 migration plan.
3. Verify the domain name: The domain name you're using for Office 365 needs to be verified well before the migration wraps up. This confirms that your users will be able to access their email once it has been migrated.
4. Configure the mail flow: Mail flow configuration between your on-premises Exchange Server and Exchange Online. Set up mail flow is important for correctly routing your email messages during migration.
5. Migrate your mailbox data: Run the migration through EdbMails Exchange migration software. Larger environments usually benefit from a batched approach, while smaller ones can often handle a single pass without issues.

Office 365 Implementation Checklist

First time setting up Office 365 for your organization? Here are some essential steps to follow:

1. Verify your domain name: Your domain needs to be verified with Office 365 before it can be used with email accounts and other applications. The steps to verify and add your domain lay out exactly how to do it.
2. Create your user accounts: Add users to Office 365 and make sure each one gets the correct license assigned.
3. Configure your DNS settings: Wrong DNS settings will stop users from reaching Office 365 applications altogether. Follow the steps to add DNS records and connect your domain to get this right.
4. Set up your email: Sort out your email domains, forwarding rules, and spam filters early. Leaving these until after the rollout creates unnecessary cleanup work later.
