Moving Mailboxes in a Hybrid Configuration – Part I

In three earlier blog posts I explained how to implement directory synchronization and how to create an Exchange hybrid configuration:

These steps will create a hybrid configuration between your on-premises Exchange 2013 environment an Exchange Online, but to move mailboxes from Exchange on-premises to Exchange online (or vice versa) you need to create an endpoint. This an on-premises Exchange 2013 server (but it can be more) where the Mailbox Replication Service (MRS) is running, used to move mailbox data from one server to another. The process is similar to an on-premises mailbox move where the MRS is responsible.

Create a migration endpoint

To create an endpoint you have to go to the Exchange Admin Center in Office 365 and login as an Office 365 tenant administrator. You can get there via the Microsoft Online Portal, select Admin | Exchange, or navigate directory to the Exchange Admin Center, and login as an Office 365 tenant administrator.

In the Exchange Admin Center dashboard, under Recipients select migration. At this point an empty screen will be shown:

Login failed because the mailbox you tried to access is being moved

In preparation of a migration from Exchange 2007 to Exchange 2013 (interorg, so new Active Directory and new Exchange deployment) I had to clean up the Exchange 2007 environment. There was one user that had a 4.5GB Mailbox with over 50,000 items in.

Unable to delete Lync 2010 Front End Pool after migrating to Lync 2013

After a (successful) migration from Lync 2010 to Lync 2013 I wanted to decommission the old Lync 2010 servers. In my previous blog post I already explained why the CMS didn’t want to move, but the next issue was challenging as well.

Before removing the last Lync front-end server you have to remove all Lync 2010 objects from this front-end server. Well known issue for example is the conference directory that for some reason always stays at the front-end server.

Migrationwiz – Exchange migration in the cloud

When migrating one Exchange organization to another organization you have to do quite some work. The traditional methods include a lot of scripting, or a 3rd party tool like Quest or BinaryTree to migrate one Exchange environment to another.

Migrationwiz is a product that can perform the migration from the cloud, they offer E-mail migrations as a service. This migration can be from any messaging platform to any messaging platform, but for this blog I’ll focus on a migration from one Exchange platform to another Exchange platform (in different datacenters).
