Install Office Online Server 2016

In Exchange 2013 you could use the Office Web Apps server in combination with Exchange server to view attachments online, without having to download these attachments first to the local workstation. Exchange 2016 is the successor of Exchange 2013, Office Online Server (OOS) 2016 is the successor of Office Web Apps 2013.

For an optimal user experience in Outlook on the Web you want an Outlook Online Server to view attachments online. Instead of downloading the attachment to your client workstation (not ideal when working on a non-trusted workstation) you can view it in your browser, and your browser will show something like this:

So how does this work?

Moving Mailboxes in a Hybrid Configuration – Part II

Before you start moving mailboxes you have to make sure that all accepted domains used by mailboxes on-premises are configured in Office 365. This can be tricky, you wouldn’t be the first admin that experience failed migration because of a domain.local email address on an on-premises Mailbox J

Now, when you want to move a mailbox from Exchange on-premises to Exchange Online, navigate again to the Exchange Admin Center, and under recipients select migration. Click the + icon and select migrate to Exchange Online to start the new migration batch wizard.

For the migration type, select Remote move migration which is supported by Exchange 2010 or later.

Click Next to continue. Select the mailboxes you want to migrate to Exchange Online, you can use the people picker feature (click the + icon under Select the users that you want to move) for this, or you can use a CSV file to select the mailboxes you want to move.

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:

Exchange 2013 Hybrid Prerequisites (Part I)

Edited: November 11, 2015

In a hybrid environment the on-premises Exchange organization (which can be either Exchange 2010 or Exchange 2013) is integrated with Exchange Online. In a hybrid configuration you basically create one ‘virtual’ Exchange organization with the following features:

  • One cross-premises Address Book;
  • Secure cross-premises mail flow;
  • Cross-premises Free/Busy information, mail tips and out-of-office features;
  • Seamless migration to Exchange Online and vice versa;
  • No recreation of OST file;
  • Automatic reconfiguration of Outlook profile;
  • OWA URL Redirect.

To create a Hybrid environment you need at least one Exchange hybrid server on-premises. This can be an Exchange 2010 server but I always recommend using an Exchange 2013 server for this because of the improved hybrid connectivity in Exchange 2013. For redundancy purposes (and performance for larger environments) you better use multiple Exchange 2013 Hybrid servers.

Another prerequisite for creating a Hybrid environment is that you must have Directory Synchronization in place, so DirSync is used for synchronization user accounts, groups and contacts, all other communication is handled by the Exchange 2013 hybrid servers as shown in the following picture:
