Overview
Section titled “Overview”As soon as you have logged into grommunio Web, it presents an overview of your personal interface. By default, it will navigate to the mailbox overview, which, traditionally, is either empty, or pre-filled by data from a migration by your administrator.

The main overview of grommunio Web is organized as follows:
Main Interface Area
Section titled “Main Interface Area”The main interface area contains reference to the main application areas. By default, these are: Mail, Calendar, Tasks and Notes. On the top right, you find personal information, such as the indicator of the user you have logged in, Reminders, Settings, Help and Logout buttons.

Shortcut Bar
Section titled “Shortcut Bar”
The Shortcut Bar combines the main functions available in the application area you are currently in. It provides quick access to common actions such as:
- creating a new item
- opening the Address Book
- refreshing the view
- printing an email
- changing the layout
New Item Dropdown
Section titled “New Item Dropdown”Clicking the small arrow on the right side of the New Item button opens a dropdown menu where different types of items can be created. The available options are:
- Email – Create a new email message.
- Appointment – Schedule a new calendar appointment.
- Meeting request – Create and send a meeting invitation.
- Contact – Add a new contact to the address book.
- Distribution list – Create a new distribution group.
- Task – Create a new task.
- Task request – Assign a task to another user.
- Sticky note – Create a note item.
Tab Bar
Section titled “Tab Bar”Below the Shortcut Bar is the Tab Bar.

The Tab Bar displays all currently opened items as tabs, such as the Inbox, new emails, appointments, meeting requests etc.
The very first tab shows the folder you are currently in. It is always pinned and cannot be closed.
Any newly created item from the New Item Dropdown (for example: Email, Appointment, Meeting) appear here as additional tabs. In addition new items can also be created by clicking the + symbol at the end of the Tab Bar.
Temporary tabs are automatically removed when:
- an item is sent
- an item is saved
- user manually closes the tab
- user refreshes browser
This tabbed view allows quick switching between multiple items without losing context.
Folder Navigation Area
Section titled “Folder Navigation Area”With the Folder Navigation Area, you can see an overview of your personal folders, as well as any attached secondary mailboxes like public folders that are accessible to you. Depending on which module you are currently using (Mail, Calendar, Contacts, etc.), the Folder Navigation Area normally displays only the folders relevant to that module. For example, in the Mail module you will see your mail folders, while in the Calendar module only calendars are shown.

Show All Option
Section titled “Show All Option”The navigation area features a Show All checkbox. When checked, Show All displays every folder associated with your mailbox, regardless of the active module. This gives you a complete overview of all folders in one view.
Main Content Area
Section titled “Main Content Area”The Main Content Area displays the primary information of the application based on the currently selected module, folder, or context.
For example, when the Inbox folder is selected in the mail module, the main content area shows all emails contained in that inbox. When another folder, search result, or item type is selected, the displayed content updates accordingly.

In many areas of grommunio Web, a built-in Search Function is available. Search results are displayed directly in the main content area, replacing the standard folder view while the search is active.
All entries shown in the main content area support sorting by different criteria, such as from, subject, date, categories, status etc. Sorting options are typically available by clicking the column headers or using the provided sorting controls.
This dynamic behavior ensures that the main content area always reflects the current working context and provides quick access to relevant information.
Data structure
Section titled “Data structure”Your primary groupware data is stored in a so-called "mailbox", or "mail store". This data contains major information such as your e-mails, calendar data, contacts, and so on. To have this managed well, the mailbox store is hierarchially organized with folders. By default, a store includes a set of default folders which also have various types. These are:
| Name | Type |
