We currently support the configuration and use of these versions of Outlook: 

  • 2010, 2013, 2016, 2019 and Outlook 365 click-to-run for 
  • Windows 2011/2016 for Mac 

All of these applications are fully compatible and benefit from all of the features of our Hosted Exchange platform. This article will outline the setup of each. 

Please note: 

We strongly recommend automatic configuration of Outlook. We operate high-availability clusters of Exchange servers and automatic configuration gives Outlook the ability to switch between clusters without losing connectivity.

Automatic Configuration (Windows)

Although automatic configuration is recommended, there may be circumstances where manual configuration is the only option. In this case, please follow the appropriate tab for the Exchange platform in question:

Offline Address Book

The Offline Address Book contains the properties of a user, such as e-mail addresses, that Microsoft Outlook requires in order to send an e-mail message and display information about the user. By using the Offline Address Book, Outlook does not have to connect to Exchange in order to resolve names or open the records for each user. This reduces network traffic and improves performance.

Note: We recommend that you download the full details of the Offline Address Book. This makes more address book information available when there is no network connectivity.

If Outlook is left running constantly in Cached Exchange Mode, it updates the Offline Address Book automatically about once a day, depending on Address Book updates on the server running Exchange. To initiate these updates manually, do the following.
