# Email Account Sharing

**Email Account Sharing** is a feature within the [[groupware]] email module that allows an account owner to grant other users or groups access to their mailbox with granular permissions.

## Legal and Policy Constraints
The [[universitatsrechenzentrum-urz]] enforces strict rules regarding who can share accounts:
- **Personal Accounts**: Sharing a personal email account with third parties is **strictly prohibited** under §6 Abs. 2 Nr. 3 of the URZ statutes.
- **Personal Exception**: A user may share access between their own staff account and their own student account, provided the system can validate the identity via an exact match of name and date of birth.
- **Functional Accounts**: Sharing is primarily intended for [[funktionsaccounts]], allowing multiple staff members to collaborate on a single mailbox.

## Permission Levels
The system provides four levels of granular access:

| Permission | Capabilities | Restrictions |
|---|---|---|
| **Read only** (Nur lesen) | View emails. | Cannot mark as read/unread, move, delete, or reply. |
| **Deputy** (Stellvertreter) | Reply to emails (using their own account, owner is CC'd); mark as read. | Cannot mark as unread, move, or delete. |
| **Use Account** (Verwende Account) | Send emails in the owner's name; edit, move, and delete emails. | No administrative rights. |
| **Manage** (Verwalten) | All "Use Account" rights. | Can modify administrative settings of the email account. |

## Technical Configuration
1. Log into [[groupware]] with the account to be shared.
2. Navigate to the **Email Module**.
3. Right-click the account $\rightarrow$ **Properties** $\rightarrow$ **Permissions** tab.
4. Assign the desired user or group and select the appropriate permission level.
