Exchange 2007 how does it work

With a migration to Microsoft , you can make a single hop from year-old technology to state-of-the-art features, including:. Microsoft also gets new features and experiences first, so you and your users can usually start using them right away. And you won't have to worry about:. Upgrading to a new version of Exchange. With Microsoft , you're always on the latest version of Exchange. This table shows your migration options and the most important factors that determine which method to use:.

The following sections provide an overview of these methods. For more detail, see Decide on a migration path. In a cutover migration, you migrate all your mailboxes, distribution groups, contacts, and so on, to Microsoft at a preselected date and time.

After the migration is complete, you shut down your on-premises Exchange servers and start using Microsoft exclusively. Cutover migration is great for small organizations that don't have many mailboxes, want to get to Microsoft quickly, and don't want to deal with some of the complexities of the other methods.

But it should be completed in a week or less, and it requires users to reconfigure their Outlook profiles. Cutover migration can handle up to 2, mailboxes, but we strongly recommend you use it to migrate a maximum of mailboxes. If you try to migrate more, you could run out of time to transfer all the mailboxes before your deadline, and your IT support staff may get overwhelmed with requests to help users reconfigure Outlook.

The Exchange accepted domains that you want to use in Microsoft need to be added as verified domains in the service. Between the time you start the migration and when you begin the completion phase, Microsoft will periodically synchronize the Microsoft and on-premises mailboxes. This lets you complete the migration without worrying about email being left behind in your on-premises mailboxes.

Users will receive new temporary passwords for their Microsoft accounts. They'll need to change their password when they sign in to their mailbox for the first time. You'll need a Microsoft license that includes Exchange Online for each user mailbox you migrate. Users will need to set up a new Outlook profile on each of their devices and download their email again. The amount of email that Outlook will download can vary. For more information, see Change how much mail to keep offline.

Staged migration is great for organizations that need to take more time to migrate their mailboxes to Microsoft but still plan to complete the migration within a few weeks. You can migrate mailboxes in batches. You control how many and which mailboxes are migrated at a given time.

You might batch mailboxes of users in the same department, for example, to make sure they're all moved at the same time. Or, you might leave executive mailboxes until the last batch. As with cutover migrations, your users will need to recreate their Outlook profiles. The Exchange accepted domains that you plan to use in Microsoft need to be added as verified domains in the service.

You'll need to create a CSV file with the full name and email address of each mailbox that you plan to migrate in a batch. You'll also need to include a new password for each mailbox that you're migrating, and send that password to each user.

The user will be prompted to change the password the first time that they sign in to their new Microsoft mailbox. Between the time you start the migration batch and when you begin the completion phase, Microsoft will periodically synchronize the Microsoft and on-premises mailboxes included in the batch.

What you need to know about a staged email migration. Perform a staged migration of email. In a full hybrid migration, your organization has many hundreds, up to tens of thousands, of mailboxes, and you want to move some or all of them to Microsoft Because these migrations are typically longer-term, hybrid migrations make it possible to:.

On this first configuration page you only need to enter the email address of your Postmaster or Administrator user. The Postmaster will receive all emails without a valid recipient as well as general POPcon status notifications. It is very important to define a real email address from inside your exchange server here because mails can be lost irretrievably if POPcon forwards some mail with no recipient information to the postmaster and that account does not exist in your exchange server.

For each server or account you need to fill in the POP3 server settings as shown below. If you are using catch-all style mailboxes mailboxes that receive email for a whole domain, regardless of the recipient part before the " " POPcon needs to filter recipients from incoming mail so only the recipients at your own internet domain are accepted.
