# Email Client Settings

Use the following settings to configure any desktop or mobile email client (Outlook, Thunderbird, Apple Mail, iOS Mail, Gmail app, etc.) with your Open-Xchange mailbox.

These settings are also available in the customer portal under **Manage Email Accounts → Email Client Settings**.

## Server Settings

| Setting                    | Value                                              |
| -------------------------- | -------------------------------------------------- |
| **Incoming Server (IMAP)** | `imap.us.appsuite.cloud`                           |
| **IMAP Port**              | `993` (SSL/TLS)                                    |
| **Incoming Server (POP3)** | `pop.us.appsuite.cloud`                            |
| **POP3 Port**              | `995` (SSL/TLS)                                    |
| **Outgoing Server (SMTP)** | `smtp.us.appsuite.cloud`                           |
| **SMTP Port**              | `465` (SSL/TLS)                                    |
| **Username**               | Your full email address (e.g., `user@example.com`) |
| **Password**               | Your email account password                        |
| **Authentication**         | Required for IMAP, POP3, and SMTP                  |

## IMAP vs. POP3

|                           | IMAP                                                    | POP3                                                    |
| ------------------------- | ------------------------------------------------------- | ------------------------------------------------------- |
| **Sync across devices**   | Yes — read, deleted, and moved messages sync everywhere | No — changes on one device do not reflect on others     |
| **Email stays on server** | Yes                                                     | No — email is downloaded and removed from the server    |
| **Recommended**           | Yes, for most users                                     | Only if you need offline-only access on a single device |

## Encryption

Always use **SSL/TLS** encryption. The server settings above all use encrypted connections by default. Do not use unencrypted connections or non-standard ports.
