Before move to technical part let me explain what is Exchange Server ?  Exchange is a Mail Solution from Microsoft . The latest version of exchange server is 2016 . You can purchase exchange server from Microsoft and you can install it in your environment .

But to install exchange application in a server to create mail server , you have follow some certen steps and you have to maintain those sever . If you don’t want to do that then take a subscription of Office365 and enjoy the online version of Exchange .

This is the mail option that get in office365 portal . But this is the mailbox.

This is more for user and to receive and send mail . But we are concern about admin part of it.





Now to open admin center of Exchange at first go to admin certer of o365 and then click on exchange .

This is exchange admin center . where in left side you will find all option to control user mailbox+permission and further config .

So let’s talk about all option one by one .







-: Migration :-

An administrator performs a staged or cutover migration to Office 365. All email, contacts, and calendar information can be migrated for each mailbox.Migration is a process by which we can send data from one location to another location . In our case we can migrate data from on-prem to O365.

This is a simple page in O365 from where you will get a step by step guidance to do migration .


This is O365 Exchange migration advisor :

Let’s understand different mode of Migration :

Migrate all mailboxes at once (cutover migration) or Express migration :

Use this type of migration if you’re running Exchange 2003, Exchange 2007, Exchange 2010, or Exchange 2013, and if there are fewer than 2000 mailboxes. You can perform a cutover migration by starting from the Exchange admin center (EAC); see Perform a cutover migration to Office 365. See Use express migration to migrate Exchange mailboxes to Office 365 to use the Express migration.

Important: With cutover migration, you can move up to 2000 mailboxes, but due to length of time it takes to create and migrate 2000 users, it is more reasonable to migrate 150 users or less.

Migrate mailboxes in batches (staged migration) :

Use this type of migration if you’re running Exchange 2003 or Exchange 2007, and there are more than 2,000 mailboxes. For an overview of staged migration, see What you need to know about a staged email migration to Office 365. To perform the migration tasks, see Perform a staged migration of Exchange Server 2003 and Exchange 2007 to Office 365.


Migrate using an integrated Exchange Server and Office 365 environment (hybrid) :

Use this type of migration to maintain both on-premises and online mailboxes for your organization and to gradually migrate users and email to Office 365. Use this type of migration if:

  • You have Exchange 2010 and more than 150-2,000 mailboxes.
  • You have Exchange 2010 and want to migrate mailboxes in small batches over time.
  • You have Exchange 2013.

Migrate email from another IMAP-enabled email system

You can use the Internet Message Access Protocol (IMAP) to migrate user email from Gmail, Exchange,, and other email systems that support IMAP migration. When you migrate the user’s email by using IMAP migration, only the items in the users’ inbox or other mail folders are migrated. Contacts, calendar items, and tasks can’t be migrated with IMAP, but they can be by a user.

IMAP migration also doesn’t create mailboxes in Office 365. You’ll have to create a mailboxfor each user before you migrate their email.

An administrator performs an IMAP migration to Office 365. All email, but not contacts or calendar information, can be migrated for each mailbox.

To migrate email from another mail system, see Migrate your IMAP mailboxes to Office 365. After the email migration is done, any new mail sent to the source email isn’t migrated.
