Set Up Outlook

Note on Autodiscover

The Autodiscover feature only works with Outlook versions up to and including O365. Newer versions (the new Outlook) no longer support Autodiscover for mailcow and require manual setup.

This is not an error of the mailcow Groupware, but a result of changes made by Microsoft.

To manually set up EAS, start the old wizard via C:\Program Files (x86)\Microsoft Office\root\Office16\OLCFG.EXE. Once the application starts, proceed with step 4 of the instructions for Outlook 2013. If the application does not open, disable the simplified account creation wizard and follow the instructions for Outlook 2013.

  1. Start Outlook.
  2. If Outlook is being started for the first time, a setup wizard will appear. Proceed to step 4.
  3. Open the File menu and click Add Account.
  4. Enter your name, email address, and password. Click Next.
  5. When prompted, re-enter your password, enable Save my credentials, and click OK.
  6. Click Allow.
  7. Click Finish.

To use EAS, start the old wizard under C:\Program Files (x86)\Microsoft Office\root\Office16\OLCFG.EXE. Once the application is open, proceed with step 4 of the instructions for Outlook 2013.

If the application does not open, you can disable the simplified account wizard and then follow the instructions for Outlook 2013.

The new Outlook (pre-installed on Windows)

Note on using the new Outlook

Credentials entered in the new Outlook are transmitted to Microsoft or their data centers. For more information, see: https://www.heise.de/news/Microsoft-krallt-sich-Zugangsdaten-Achtung-vorm-neuen-Outlook-9357691.html

For security reasons, we strongly advise against using the new Outlook.

Warning

The new Outlook does not support CalDAV or CardDAV calendars – neither natively nor via Outlook CalDav Synchronizer.

If you still wish to use the new Outlook, follow these steps:

  1. Start the new Outlook.
  2. If no account is set up yet, the setup wizard will open automatically. In this case, proceed directly to step 5.
  3. Click the gear icon in the top right to open the settings.
  4. Navigate to Accounts > Your Accounts and click Add Account on the left.
  5. Enter your email address and click Next.
  6. Select IMAP as the provider.
  7. In the Password field, enter the password for your email account.
  8. For the IMAP Incoming Server, enter hosted.mailcow.de.
  9. Typically, use port 993 (IMAPS).
  10. The Secure Connection Type should be SSL/TLS (for IMAPS) or STARTTLS (for IMAP).
  11. For the SMTP Username, re-enter your email address (if not pre-filled).
  12. For the SMTP Password, re-enter your email password.
  13. For the SMTP Outgoing Server, again enter hosted.mailcow.de.
  14. Ideally, use port 587.
  15. The Secure Connection Type should be SSL/TLS (for SMTPS/Submission) or STARTTLS (for SMTP).
  16. Click Next to complete the setup.

Note

During setup, Microsoft may ask about privacy options. Decide for yourself whether and what information you wish to share.
