# Email troubleshooting

> Fix problems with outbound and inbound email.

Start in [Email activity](https://desk.quibtech.com/docs/admin/notifications/email-activity.md). It shows each email, its status, and any error.

## Outbound

> [accordion] Nothing sends
>
> Check that **Send notification emails** is on.

> [accordion] The connection fails or times out
>
> Check the port and SSL/TLS: 465 with **Use SSL/TLS** on, or 587 with it off.

> [accordion] The test works, but notifications don’t send
>
> Open **Waiting to send** and select **Send now**. It says why if it can’t send. Contact whoever set up this help desk.

> [accordion] Email lands in spam
>
> Set up SPF and DKIM on the sending domain.

> [accordion] Microsoft 365 says the client secret is invalid
>
> You may have entered the **Secret ID**. Create a new secret and enter its **Value**.

> [accordion] Microsoft 365 says the secret expired
>
> Create a new secret and enter its **Value**.

> [accordion] Microsoft 365 says you aren’t allowed to send
>
> Check the Exchange permission covers the mailbox. It can take up to two hours to apply.

> [accordion] Microsoft 365 can’t find the mailbox
>
> Use the mailbox’s primary address as the **From address**, not an alias.

## Inbound

> [accordion] Email to the inbound address does nothing
>
> Check that **Receive email at the inbound address** is on, then check Email activity. Contact whoever set up this help desk.

> [accordion] Replies open new tickets
>
> Set the **Reply-to address** to your inbound address.

> [accordion] Senders are told the address only accepts replies
>
> **Open a new ticket from email that is not a reply** is off. Turn it on to accept new email.

> [accordion] Your organization stopped receiving other email
>
> Contact whoever set up this help desk.
