Configure iPhone: Infomaniak Mail, Calendar, and Contacts

The InfoSwitch Team 12 février 2026 8 min read

The iPhone integrates perfectly with Infomaniak services thanks to native support for IMAP, CalDAV, and CardDAV protocols. In just a few minutes, you can sync your emails, calendars, and contacts without installing any third-party app. Here\'s the step-by-step guide to setting everything up.

Create My Infomaniak Mail Account

What You Need

Before you begin, make sure you have:

  • Your full Infomaniak email address
  • Your password
  • An iPhone running iOS 15 or later (earlier versions also work, but the interface may differ)

The setup is done entirely in the iPhone Settings, with no additional app download required.

Setting Up Email

The native iOS Mail app is fully compatible with Infomaniak accounts via the IMAP protocol.

1

Open Settings

Go to Settings → Mail → Accounts → Add Account.

2

Choose "Other"

From the list of providers, select Other at the bottom of the list, then Add Mail Account.

3

Enter Your Information

Fill in:

  • Name: The name displayed to recipients
  • Email: Your Infomaniak email address
  • Password: Your password
  • Description: A name to identify this account (e.g., "Pro Infomaniak")

Tap Next.

4

Select IMAP

Choose IMAP (not POP) to sync your emails across all your devices.

5

Configure the Servers

Enter the following settings:

Incoming Mail Server (IMAP)

  • Host Name: mail.infomaniak.com
  • Username: Your full email address
  • Password: Your password

Outgoing Mail Server (SMTP)

  • Host Name: mail.infomaniak.com
  • Username: Your full email address
  • Password: Your password
6

Confirm

Tap Next. iOS will verify the settings and add the account. This may take a few seconds.

Your emails now appear in the Mail app. Synchronization is bidirectional: emails read or deleted on the iPhone will also be updated in webmail and on your other devices.

Setting Up the Calendar (CalDAV)

iOS natively supports CalDAV, the protocol used by Infomaniak for calendar synchronization.

1

Add a CalDAV Account

Go to Settings → Calendar → Accounts → Add Account → Other.

Select Add CalDAV Account.

2

Enter the Settings

  • Server: caldav.infomaniak.com
  • Username: Your Infomaniak email address
  • Password: Your password
  • Description: A name for this account (e.g., "Work Calendar")
3

Confirm and Sync

Tap Next. iOS connects to the server and retrieves your calendars. All your events appear in the native Calendar app.

Multiple Calendars

If you have multiple calendars in your Infomaniak account (personal, professional, projects...), they will all be synced. You can choose which ones to display in the Calendar app using the filter options.

Setting Up Contacts (CardDAV)

Contact synchronization works similarly via CardDAV.

1

Add a CardDAV Account

Go to Settings → Contacts → Accounts → Add Account → Other.

Select Add CardDAV Account.

2

Enter the Settings

  • Server: carddav.infomaniak.com
  • Username: Your Infomaniak email address
  • Password: Your password
  • Description: A name for this account (e.g., "Work Contacts")
3

Confirm

Tap Next. Your Infomaniak contacts appear in the native Contacts app.

Advanced Configuration

Verifying SSL/TLS Settings

To ensure the security of your communications, verify that SSL/TLS is enabled:

  1. Go to Settings → Mail → Accounts
  2. Select your Infomaniak account
  3. Tap Account then Advanced
  4. Verify that Use SSL is enabled
  5. The IMAP port should be 993

For the SMTP server:

  1. Go back and tap SMTP
  2. Select the mail.infomaniak.com server
  3. Verify that Use SSL is enabled
  4. The port should be 465 or 587

Choosing the Default Calendar

If you have multiple calendar accounts (iCloud, Infomaniak, etc.), set which one to use by default:

  1. Go to Settings → Calendar
  2. Tap Default Calendar
  3. Select your Infomaniak calendar

New events created from the iPhone will automatically be added to this calendar.

Setting the Default Address Book

Similarly for contacts:

  1. Go to Settings → Contacts
  2. Tap Default Account
  3. Select your Infomaniak account

Push Notifications

By default, iOS retrieves emails at regular intervals (fetch). To receive notifications instantly:

  1. Go to Settings → Mail → Accounts → Fetch New Data
  2. Select your Infomaniak account
  3. Choose Push if available, or Fetch with a short interval (15 minutes)

Note: Push consumes more battery. If battery life is critical, prefer fetching every 30 minutes.

Troubleshooting Common Issues

Unable to Connect

  • Verify you\'re using the full email address as the username
  • Check your password (watch for capitalization)
  • Try logging into Infomaniak webmail to confirm the account works
  • If you\'ve enabled 2FA, you must use an app password

Sent Emails Stuck in Outbox

  • Check the SMTP server settings (mail.infomaniak.com, port 465 with SSL)
  • Make sure SMTP authentication is enabled
  • Check your internet connection

Calendar Not Syncing

  • Verify the CalDAV server address (caldav.infomaniak.com)
  • Force a sync: open the Calendar app and pull down to refresh
  • Delete and recreate the CalDAV account

Duplicate Contacts

If you see duplicate contacts, it\'s likely because they exist in both iCloud and your Infomaniak account. You can:

  • Disable iCloud contact sync
  • Merge duplicates in the Contacts app (iOS often detects duplicates)
  • Choose to display only Infomaniak contacts

2FA and App Passwords

If you\'ve enabled two-factor authentication on your Infomaniak account, the Mail app won\'t be able to connect with your regular password. You need to create a dedicated app password in Infomaniak Manager → Security → App Passwords.

Using the kDrive App

In addition to native apps, you can install the kDrive app from the App Store. It lets you access files stored on kDrive, share them, and sync them with your iPhone.

The kDrive app integrates with iOS: you can save files to kDrive from any app, and open kDrive files in other apps.

Conclusion

The iPhone is fully compatible with Infomaniak services. In just a few minutes, you can set up emails, calendars, and contacts using native apps, with no need for third-party applications.

Standard protocols (IMAP, CalDAV, CardDAV) ensure reliable, bidirectional synchronization. Your data stays up to date across all your devices, whether it\'s your iPhone, your Mac, or Infomaniak webmail.
