Migration to Exchange Online

  • Microsoft Outlook automatically adopts the new configuration
    • The signature (business card) may not be adopted. You can reactivate it and copy the content from a previously sent mail.
  • All other mail clients must be reconfigured:
    • Remove existing account
    • Reconfigure the e-mail account (see Client configuration)

Confidential, sensitive information should never be sent by e-mail!

We are now using an external filtering service that filters inbound, outbound and internal email, therefore confidential, sensitive information should never be sent by email.
