OX App Suite mail apps use imap.us.appsuite.cloud (port 993, SSL/TLS) and smtp.us.appsuite.cloud (port 465 SSL/TLS or 587 STARTTLS).
The settings at a glance
| Setting | Value |
|---|---|
| Username | Your full email address, for example [email protected] |
| Password | The password of this OX mailbox |
| Incoming server (IMAP) | imap.us.appsuite.cloud, port 993, SSL/TLS |
| Outgoing server (SMTP) | smtp.us.appsuite.cloud, port 465 with SSL/TLS, or port 587 with STARTTLS |
| Authentication | Required for incoming and outgoing mail (normal password, same username and password) |
| Webmail | https://us.appsuite.cloud/appsuite/ |
| Calendars and contacts (CalDAV and CardDAV) | https://dav.us.appsuite.cloud/, same username and password |
These values are the same for every OX mailbox from ElySpace. Your client area shows them too: open the OX service, then Manage Email Accounts and the tabs Email Client Settings and Calendars and Contacts.
IMAP or POP3?
Use IMAP. Your mail stays on the OX servers, so webmail, phone and computer show the same folders and stay in sync. OX also offers POP3 at pop.us.appsuite.cloud, port 995 with SSL/TLS. POP3 downloads mail to one device, and other devices don't see what you read or deleted there.
Other ports
| Service | Server | Recommended | Alternative |
|---|---|---|---|
| IMAP | imap.us.appsuite.cloud | 993 SSL/TLS | 143 STARTTLS |
| POP3 | pop.us.appsuite.cloud | 995 SSL/TLS | - |
| SMTP | smtp.us.appsuite.cloud | 465 SSL/TLS | 587 STARTTLS |
Some networks and internet providers block port 465. If sending fails there, switch SMTP to port 587 with STARTTLS (in some apps called "TLS").
DNS records for your domain
Mail apps don't need these, but your domain does: its MX records must point to the four OX mail servers, and its SPF record must include OX. The values and steps are in OX App Suite: point your domain's email DNS.
Step-by-step setup for your device
- Set up OX App Suite email on iPhone or iPad
- Set up OX App Suite email on Android
- Set up OX App Suite email in Outlook
- Set up OX App Suite email on a Mac (Apple Mail)
Inside OX webmail you'll also find a setup wizard: click the Settings icon in the menu bar and choose Connect your device.
Common problems
Receiving works, sending fails
Turn on authentication for the outgoing server ("My outgoing server requires authentication" or similar) with the same username and password. If it still fails, use port 587 with STARTTLS.
Certificate warning
The server name is wrong, usually mail.yourdomain.com. Change it to imap.us.appsuite.cloud and smtp.us.appsuite.cloud.
The app says the username or password is wrong
The username is the full email address. Test the password in OX webmail; if it fails there too, set a new one in the client area (see Create OX mailboxes and log in to OX webmail).
Login fails for every app and webmail at once
If webmail shows "User is deactivated (AUTHORIZATION-0001)", the OX service has expired. Pay the renewal invoice (see Pay an invoice).
