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.

Members of the university are offered several options to connect to Exchange Online.

Standard access to personal mailboxes and functional mailboxes:

• Outlook in Web Browser
• Microsoft Outlook 365 - Standard Anwendung an der OTH Regensburg
• Outlook for Android App - Standard Android Application

Additionally, the following options are provided:

• Allgemeine Infos

The following apps are not regularly supported by the IT Center:

• Exchange mit Apple MacOS
• Exchange mit iOS
• Exchange mit Gmail
• Exchange mit Gnome Evolution
• Exchange mit Thunderbird
• Exchange mit Samsung Mail App

The mentioned apps are approved for access to Exchange Online for all university members. Generally, each app (email client) must be registered and approved by the IT Center to connect 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.

• 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 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.
