Outlook on Windows

This web site describes, how you configure Microsoft 2019 on a DESY Windows 10 device with your DESY account. After the configuration you will be able to send and receive emails with your account as well as view calendars and organize appointments this way.


Note: The following instructions were created with Microsoft Outlook 2019 under Windows 10.

In order to use Outlook in connection with the DESY email and calendar service (Zimbra), it is necessary that the so-called "Zimbra Connector for Outlook" (ZCO) is installed. Without the Zimbra Connector for Outlook, the connection is not possible.

The Zimbra Connector can be installed via NetInstall/DSM. During the installation all necessary configurations are done automatically and a corresponding Zimbra profile for Outlook with the name "CreateZimbraProfile.exe" or "Zimbra" is created.

Please note that when you start Outlook for the first time, you will be prompted to select the Zimbra profile with which you want to start Outlook. Afterwards a configuration window opens in which "zco.desy.de:443" should be entered as server name. In this window please enter your account name and password once.

Configuration Settings for the Zimbra Connector for Outlook

Depending on the size of your mailbox, the initial synchronization may take several hours. Please do not interrupt this process. During the synchronization, you can use the web client (https://mail.desy.de) without restrictions and access your mails and calendar using it.

Once the synchronization is complete, please remove the Outlook rule "Delete categories of e-mails" as follows:

  1. Select the "Start" tab and click on the "Rules" -> "Manage rule and notifications..." menu item.
  2. Here please delete the previously mentioned rule "Delete categories of emails".

After you have completed this step, you can use Outlook in connection with the central e-mail system at DESY. If required, you can find information on the web site about advanced configurations.
