4. Create a first profile (for the calendar or the contacts - a second profile will need to be created to synchronize both) by clicking on the + icon:
   
5. Choose a generic profile type (first radio button):
   
6. As profile name, enter the name of the Infomaniak calendar or address book you want to synchronize
7. Click the button to choose calendar or contacts and then confirm with OK:

9. Enter the information (URL and username) obtained on config.infomaniak.com
10. Enter the password
    1. If two-step verification is not enabled, use the password of your Infomaniak user account
    2. If two-step verification is enabled, generate an application password here: https://manager.infomaniak.com/v3/profile/application-password
11. Enter the email address, that of your user account
12. Click on Test or discover settings:
    
13. Choose the Infomaniak calendar to synchronize on the window that opens:
    
14. Additional information may then appear automatically in some fields
15. Activate the synchronization box:
    
16. Save a second profile if necessary (start again at point 4 in this case)
17. Finish with OK at the bottom right
18. A restart of Outlook may be necessary to update the added information

Resolving Duplicate Events

If you notice duplicated events in your Outlook calendar that are not duplicated on calendar.infomaniak.com, apply these settings:

1. Click to Show Advanced Settings
2. Click on Event Mapping Configuration
3. Click on the box to enable Use GlobalAppointmentID for UID attribute
4. Click on the box to enable Cleanup duplicate events
   
5. Save the modifications by clicking on the OK button
   

This deletion of duplicate events and potentially duplicate invitations may result in a notification of event refusal to the organizer, however this has no impact on the participant's initial choice.
