===== Migration from Exchange to Exchange Online =====
The mailboxes of university members will be migrated during the lecture-free period until the start of the summer semester 2025. The migration will be carried out by department and faculty. University members will be informed via email a few days before the migration of their mailboxes.


===== FAQ and Known Issues After the Migration =====
  * **Shared Mailboxes:** If you encounter issues with your functional mailboxes after the migration (e.g., unable to send emails), these mailboxes must be added as separate mailboxes in email clients like Outlook.

  * **Quota:** Migration of mailboxes with increased quota in Exchange on-premises (current email system): These mailboxes will also be migrated and will **temporarily** have an increased quota in Exchange Online. Meanwhile, an email archive is being introduced. The goal is to standardize the quota afterward.
  * **Shared Calendars and Rooms:** After the migration, access to shared calendars or rooms (both referred to as resources) may be temporarily restricted or unavailable. This can happen if the resources are in different systems, current Exchange and Exchange Online. This is a temporary limitation that will be resolved after the migration of all mailboxes and resources.
  * **Certificates** for the mobile Outlook app for **iOS** and **Android** are currently not working. This appears to be an app-related issue.
