===== Microsoft Exchange Online =====
Artikel 25.02.2025

Microsoft Exchange Online is the email system of OTH Regensburg. Microsoft Exchange Online is a cloud-based email service that provides emails, calendars, contacts, and tasks. University members can connect to Exchange Online using apps like Outlook or through a browser like Edge to access their emails and collaboration features such as shared mailboxes or shared calendars.

<note tip>Modern mail applications support the simultaneous use of multiple accounts. We recommend configuring your organizational email account directly within your preferred mail app. This eliminates the need to forward messages to personal email addresses. Please note that external email forwarding is not permitted due to security and compliance policies.</note>

===== 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. Link to re-add functional mailbox {{ :public:email:exchangeonline:funktionspostfach_neu_einbinden_v2.pdf | Funktionspostfach neu einbinden}}
  * **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.
  * **Forwarding Error Message** – Automatic forwarding to external email systems (such as GMX) is not permitted for staff (academic and academic support personnel) and is also technically blocked. Forwarding is allowed for students. In case of error messages, please check your inbox rules. [[public:email:exchangeonline:Weiterleitungen| Deactivate E-Mail Forwarding]]
  * **Publishing** a certificate in the GAL is possible if all other mailboxes have been removed from Outlook.
  * **Automatic** **Reply** for Shared Mailbox – Several users have set up automatic addition of the shared mailbox. In this case, you can only configure the automatic reply in Outlook Web by opening the shared mailbox account directly.
  * Are you missing some emails? This might be due to the current view settings in your Outlook inbox. Instructions on how to change this can be found in the documentation:* [[en:public:email:exchangeonline:ansichtrelevanz|Turn off Focused Inbox in Outlook ]]
