# Alarm emails for a Boss’nX account: address, muting and troubleshooting

Context: Boss’nX: Users of a supervision or hypervision, Edit form of a regular account

In Boss’nX, each account can receive the supervision’s alarms by email. From **Users**, you choose an account’s notification address, separate from its login username, and you suspend or resume sending without erasing that address. The alarms concerned depend on the [alarm rules of its role](https://wiki.can-nx.com/en/guides/boss-role-notifications/).

Intended for people authorized to edit the details of a regular account. For the **Supermanager** row, follow [the owner notifications](https://wiki.can-nx.com/en/guides/boss-owner-notifications/).

## Change the address or suspend delivery

1. Open **Menu → Users** in the supervision or **Hypervision users** in the aggregated view and find the account, as described in [view accounts](https://wiki.can-nx.com/en/guides/boss-users-consult/).
2. Click **Edit** in its row.
3. In **Account details**, fill in **Notification email** with the address intended for alarms. Fictional example: `maintenance@example.invalid`. This field does not change **Username**.
4. Set **Receive alarm emails**. Turn the switch off to suspend delivery without erasing the address; turn it back on to request that delivery resume according to the role’s rules.
5. If the **Password** field appears, leave it empty to keep the current password. Also keep the role and the display name when you only change the notifications.
6. Click **Save changes**, then wait for **User updated successfully.** and for the form to close.

Before submitting, **Cancel** closes the form without keeping what you entered. To revert a change that was already saved, reopen the account, restore the address or switch position you want and save again. The other account fields are described in [edit an account](https://wiki.can-nx.com/en/guides/boss-users-edit/).

## Read the Notification email column

| Display | Meaning |
| --- | --- |
| Struck-through address with **Muted** | The delivery switch is off. The address is kept for later reactivation. |
| **↳ login email** | No notification address is set: the account’s login address is used as a fallback. |
| **⚠ none** | Neither a notification address nor a login address is available. |

To suspend all sending, use the switch: erasing the dedicated address leaves the fallback to the login email. The address, its absence or the **Muted** badge do not change the password and do not delete the account.

## Check the result

1. Check the **Notification email** column on the account’s row. Use **Refresh** if needed and wait for a successful load.
2. Check that **Muted** is present or absent, according to the setting you want.
3. Actual delivery is confirmed when the person concerned receives an alarm email.

## Troubleshooting

If an account does not receive the expected alarms:

1. Confirm the relevant account and supervision in **Users**.
2. If **Muted** appears, check with the person concerned whether the suspension is intended. To resume delivery, turn the switch back on, then save.
3. If **⚠ none** appears, fill in a valid notification address, save and read the row again. If a dedicated address exists, check its spelling.
4. Have the account’s role, its alarm tags and the selected severities checked in [the notification rules](https://wiki.can-nx.com/en/guides/boss-role-notifications/). A disabled rule or an alarm that does not match the rules is corrected in the role, not by changing the password.

If saving is refused with **Invalid email format.**, correct the address. For other common questions, see [the accounts and sharing FAQ](https://wiki.can-nx.com/en/guides/boss-users-help/).

If an expected notification is still missing or if the save error persists, contact support@can-nx.com. Specify the product, the supervision, the alarm and its time, any message and the checks already made, without sending any password or secret.
