# Groupware

**Groupware** is the central collaboration platform used and operated by the Universität Greifswald (provided by the [[universitatsrechenzentrum-urz]] for its members and the [[universitat-greifswald]]). It serves as a modular hub for communication, organization, administrative tasks, scheduling, and administrative support requests, hosting critical services including the URZ ticket system, webmail, calendars, and address books.

## Access and Authentication

### Web Access
The system is accessible via the web at: `groupware.uni-greifswald.de` (or `https://groupware.uni-greifswald.de`). Authentication is performed using the [[zentraler-nutzeraccount]].

### Troubleshooting Login
If login fails, the URZ recommends the following workflow:
1. Attempt to log in to the [[ums]] (Account Management).
2. If [[ums]] login fails: The password must be reset via the URZ.
3. If [[ums]] login works but Groupware fails: Contact the URZ Hotline.

### External Synchronization
The platform supports remote access and synchronization with external clients to ensure data consistency across devices using [[dav-synchronisation]].

- **Protocols**:
    - **Calendar**: Synchronized to external clients using [[caldav]].
    - **Address Book**: Synchronized to external clients using [[carddav]].
- **Server Address**: `groupware.uni-greifswald.de`
- **Supported Clients**:
    - **macOS**: Native integration via System Settings.
    - **Desktop**: [[mozilla-thunderbird]] and [[microsoft-outlook]].
    - **Mobile**: Android and iOS.

## Functional Modules and Features

The platform consists of several integrated modules and services:

- **E-Mail / Webmail**: The primary communication tool, providing central web-based email access and management (Webmailer). It includes server-side configuration via [[groupware-email-settings]] and advanced features such as [[groupware-email-templates]].
    - **S/MIME Support**: The module includes integrated support for [[smime]], allowing users to import their own digital certificates, digitally sign outgoing emails, and encrypt outgoing emails (provided the recipient's public certificate is available in the [[public-smime-certificate-list]]).
- **Address Book (Adressbuch)**: A tool for managing professional contacts and a directory of university contacts, featuring advanced [[groupware-address-book-administration]] capabilities.
- **Calendar (Kalender)**: Used for scheduling, appointment management, and time management. It supports:
    - **Personal Calendars**: For individual use, meeting invitations, and personal scheduling with granular [[groupware-calendar-settings]].
    - **[[gruppenkalender]] / Group Calendars**: For organizational planning, such as shift or vacation schedules, and group/shared scheduling.
    - **Resource Calendars / Resource Scheduling**: For booking rooms or specific equipment. This includes specialized [[ressourcen-kalender]] for booking shared assets.
    - **Resource Management**: Allows for the reservation and administrative confirmation of university resources.
    - **Optimization**: [[kalender-favoriten]] and [[groupware-kalender-favoriten]] for optimizing the view of multiple shared calendars.
    - **Management**: Data import, duplicate removal, and availability sharing. It includes [[groupware-calendar-management]] for visualizing multiple schedules.
    - **Migration**: The ability to migrate external data via [[groupware-calendar-import]], including the ability to perform imports using ICS files.
- **File Module**: A storage and organization system that integrates with the Address Book; shared address books automatically generate corresponding folder structures here.
- **Ticket System (Ticketsystem)**: The official channel and primary interface for reporting technical issues, submitting support requests, and requesting support from the URZ regarding "CAMPUS-IT" issues. It is described as a structured support request module used to contact the URZ and other university areas for technical assistance. Detailed usage of this module is documented in [[groupware-ticketsystem-usage]].
- **Additional Functions**: A set of [[groupware-additional-functions]] which include:
    - **Group Management (Gruppenverwaltung)**
    - **Address Lists (Adresslisten)**
- **Task Lists**: Included as part of the platform's organizational capabilities.

## User Interface and Customization

### Interface Navigation
The Groupware interface is customizable to suit the user's workflow:
- **Module Bar**: Provides quick access to active modules.
- **App Selection Grid**: A 3x3 grid in the top right corner (also referred to as **Applications/Anwendungen**) used to browse and add modules to the module bar.
- **Customization**: Users can remove rarely used modules from the module bar via a **right-click** action.

### User Settings and Account Management
Users have control over several functional and aesthetic settings:
- **Email Composition**: Default behaviors for drafting new messages can be configured. Users can also configure personal settings such as email signatures and templates.
- **Interface Appearance**: Users can enable or disable smileys.
- **Notifications**: Sound settings can be managed, allowing users to mute all events or specifically target email and reminder alerts.

## Administration and Configuration

### Profile Management
User profile data in Groupware is synchronized from the central authentication system. Because of this synchronization, profile fields are effectively read-only; any manual edits are overwritten during the next login process. The identity displayed is determined by the **Primary Email Address** set in the [[ums]].

### Synchronization Administration
Users can manage their synchronization preferences and settings via the **"My Account"** section of the Groupware web interface. This includes:
- Activation of specific resources (controlling which resources are exposed to external clients).
- The "Allow deletion via synchronization" override for Android devices.

## Functional Limitations
- **Account Types**: While personalized accounts have full access, [[funktionsaccount]] users are restricted to only the **E-Mail** and **Adressbuch** modules.
- **Email Signatures**: The standard signature settings only support plain text. For signatures containing images, users must create [[groupware-email-templates]].

## Support Integration and Role in IT Support

Support for Groupware and other Campus-IT services is provided by the URZ via the internal **Ticket-System** and the hotline (ext. 1420).

Groupware serves as the host for the **URZ Ticket System**, which is the primary digital interface for users to report and track Campus-IT problems. The Ticket-System is the recommended method for contacting the URZ regarding Campus-IT problems. Its specific role is described as follows across different sources:

- According to `output/rz_uni_greifswald_de_dienste_allgemein_device_management_system_mobile_geraete__.md`, it serves as the official channel for reporting and managing support requests related to [[campus-it]] and other central IT services.
- According to `output/rz_uni_greifswald_de_dienste_allgemein_ressourcen.md`, it is the primary digital contact channel used by the [[universitatsrechenzentrum-urz]] for reporting and resolving problems related to **Campus-IT** (central URZ services).

- According to `output/rz_uni_greifswald_de_rechenzentrum_aktuelles_news.md`, the URZ Ticket System is the primary interface for users to contact the [[universitatsrechenzentrum-urz]] for support regarding Campus-IT problems.
- According to `output/rz_uni_greifswald_de_rechenzentrum_information_ausfallstatistik.md`, Groupware serves as the hosting platform for the [[universitatsrechenzentrum-urz]] ticket system, which is the primary channel for reporting [[campus-it]] problems.
- According to `output/rz_uni_greifswald_de_rechenzentrum_information_kontakt_standort.md`, Groupware serves as the host for the [[universitatsrechenzentrum-urz]] ticket system, which is the primary method for reporting and managing [[campus-it]] support requests.
