Getting Started
This chapter takes you from the sign-in page to your first steps in grommunio Web. After reading it, you know where everything is on the screen and how to find things quickly.
What you need
Section titled “What you need”grommunio Web runs in any current version of Google Chrome, Microsoft Edge, Mozilla Firefox and Apple Safari, and in browsers based on them. Use an up-to-date browser for the best experience. Some features depend on the browser:
- Dragging attachments to the desktop and Save selection to folder work in Chromium-based browsers (Chrome, Edge, Brave and others).
- Desktop notifications need your permission in the browser.
- Your browser may offer to install grommunio Web as an app and to register it as the handler for
mailto:links.
Signing in
Section titled “Signing in”- Open the address your administrator gave you, for example
https://mail.example.com/web. - Enter your user name or e-mail address and your password.
- Optionally tick Remember me so that you stay signed in on this computer.
- Click Sign In.

If your organization uses single sign-on, the same sign-in page is used for grommunio Web, Chat, Files, Meet and Archive, and you are signed in to all of them at once. Your administrator may offer additional sign-in methods on this page.
The Welcome Assistant
Section titled “The Welcome Assistant”The first time you sign in, grommunio Web greets you with the Welcome to grommunio Web dialog. Choose your preferences and click Get Started. You can change every one of them later in Settings.

Tab bar
Section titled “Tab bar”
grommunio Web works with tabs, like a browser. The first tab always shows the current folder and cannot be closed.

You can switch between them without losing anything, for example to look up an appointment while you write a mail.
- Click + at the end of the tab bar to create a new item of the current type.
- Close a tab with the × on the tab. If the item has unsaved changes, grommunio Web asks whether you really want to close it.
- The tab of an item closes automatically when you send it or click Save & Close.
Folder pane
Section titled “Folder pane”
The folder pane lists the folders of the current application. In Mail you see:
- Favourites: folders you use most often, at the top for quick access. See Favorites.
- Your mailbox with the Inbox and its subfolders, Drafts, Outbox, Sent Items, Deleted Items, Junk Email and your own folders.
- Shared mailboxes and folders others have shared with you.
- Public Folders of your organization.
- Open Shared Mails + at the bottom, to open a mailbox or folder someone has shared with you.
