Open and share mailboxes in webmail

Webmail shows every mailbox this browser can open in one list. That is every mailbox your Coritan account opens (your own, the ones you added and the ones shared with you), and any mailbox signed in on this browser with its own password. The account menu at the top right lists them, and the Mailboxes tab of settings manages your account's list and who else can open your mailboxes. Each mailbox keeps its own folders, labels and settings.

• The Mailboxes tab needs your Coritan account. Sign in on coritan.com, or sign in to webmail with your coritan.gg address and your Coritan password (Sign in to webmail).
• To add a mailbox to your account, have its address and password, and its two-factor code if it asks for one.
• To share a mailbox, you must own it and know your Coritan password. The other person needs a Coritan account.

The account menu and the Mailboxes tab describe each mailbox in the same words:

Your mailbox

The mailbox you took with your account. It stays with your account, and you cannot remove it. See Get a coritan.gg mailbox.

Added to your account

A mailbox you added with its password, such as one on your Mail Hosting service. Your account owns it in webmail.

Given to you

A mailbox an admin gave to your account. Only an admin can take it back.

Shared with you

A mailbox its owner shared with you to read, organise and send from.

View only

A mailbox shared with you to read, and nothing more.

Staff mailbox

A mailbox shared with you as a member of Coritan staff, through your staff link. It opens only while your Coritan account has two-factor authentication on.

Only on this browser

A mailbox signed in here with its own address and password. Your Coritan account does not list it, so it does not open anywhere else.

On the Mailboxes tab, a mailbox that is turned off reads Turned off by whoever manages it, and one we cannot reach at the moment reads Cannot be reached right now. The account menu says Disabled, so it cannot be opened and Not reachable right now. Neither opens until that changes.

To open another mailbox, select it in the account menu, or select Open beside it on the Mailboxes tab. Switch between mailboxes says what happens to the message you are writing.

A mailbox you add to your account opens wherever you sign in to Coritan. You can add a mailbox that Coritan hosts on this site and that no other Coritan account owns, such as one on your Mail Hosting service.

1. Go to Settings, then the Mailboxes tab.
2. Select Add a mailbox to your account. For a mailbox signed in on this browser already, select Add to your account… beside it instead.
3. Enter the mailbox's Email address and Password, then select Add mailbox.
4. If the mailbox has two-factor sign-in on, enter the code from its authenticator app in Two-factor code, then select Add mailbox again.

A message says alex@example.com is in your mailboxes now., and the list shows the mailbox as Added to your account. We check the password once and do not keep it.

To read a mailbox on this browser only, without adding it to your account, use Add another mailbox in the account menu instead (Add another mailbox).

When someone shares a mailbox with you, it waits for your answer. The account menu shows An invitation is waiting.

1. Select An invitation is waiting in the account menu, or go to the Mailboxes tab.
2. Under Invitations, read who shared the mailbox and the access they gave you.
3. Select Accept to add the mailbox to your list, or Decline to turn it down.

If your account has no mailbox yet, Webmail lists the invitations on its first page, each with Accept and Decline.

Only the owner of a mailbox can share it. The people you share it with see it in their own webmail beside their mailboxes. Your password, two-factor authentication and app passwords stay yours.

1. Open the mailbox you want to share, then go to Settings and the Mailboxes tab.
2. Under Sharing, in Invite someone, enter the email the other person signs in to Coritan with.
3. In Access, choose what they can do:
   • Can read, organize and send: they read, organise and send as the mailbox, and can set up their own mail apps for it.
   • Can only read: they read the mail and change nothing.
4. Enter your Coritan password in the field under them.
5. Select Share.

A message says We invited alex@example.com. The person's row reads Invited, has not accepted yet until they accept, then Has access. Sharing again with someone already on the list changes their access to what you chose.

A mailbox can be shared with up to 50 people, and you can send up to 20 invitations an hour.

People you share with keep their own view settings, such as Density and Undo send. The mailbox's name, signatures, filters, forwarding and automatic reply stay yours to change (Who sees each tab).

1. Open the mailbox, then go to the Mailboxes tab.
2. Under Sharing, find the person.
3. Choose another access in the list on their row. To end their access, select the bin button on the row, then Remove access, or Withdraw invitation for someone who has not accepted yet.

The change takes effect at once. When you remove someone, the devices they set up for the mailbox on the Mail apps tab stop signing in too.

Access given by an admin shows Given by an admin and has no controls, because only an admin can change it.

1. Go to the Mailboxes tab.
2. Beside the mailbox, select Remove… for one you added, or Leave… for one shared with you.
3. Confirm with Remove mailbox or Leave mailbox.

A message says alex@example.com is no longer in your mailboxes. A mailbox you remove stays as it is, mail included, and you can add it again with its password. After you leave one, its owner can invite you again. Your own mailbox, a staff mailbox, and a mailbox or access an admin gave you have neither button.

If the mailbox is on screen, webmail opens another one first.

That address and password do not match a mailbox you can add.

The address or the password is wrong, or the mailbox is not one that can be added to a Coritan account. Check both and try again.

That two-factor code is not right.

Enter the code the mailbox's authenticator app shows now. Codes change every 30 seconds.

This mailbox belongs to another Coritan account. Ask its owner to share it with you.

Another account owns the mailbox. Its owner can share it with you from their Mailboxes tab.

No Coritan account uses that email address.

The email you entered under Invite someone is not the sign-in email of a Coritan account. Ask the person which email they sign in with, or ask them to create an account first.

Incorrect account password.

Enter the password you sign in to your Coritan account with, not the mailbox's password.

A mailbox can be shared with at most 50 people.

Remove someone who no longer needs access, then share again.

A mailbox you added to your account left your list

Someone changed or reset its password other than through your Coritan account: from its Mail Hosting service, or on the Security tab while signed in with the mailbox's own password. The people you had shared it with lost their access too. Add the mailbox again with its new password, then share it again.

Turn on two-factor for your Coritan account to open it

The mailbox is a staff mailbox. Select Turn on two-factor beside it, and turn on two-factor authentication for your account. The mailbox then opens.

Open another mailbox first, then remove alex@example.com.

The mailbox is on screen and webmail has no other mailbox to open. Add or open another mailbox, then try again.

A message that says there were too many requests

Your account can add up to 10 mailboxes an hour and send up to 20 invitations an hour. Wait, then try again.
