Modify the IMAP special folders of an email address
This guide explains how to change the location of certain folders present in the directory structure of your email address.
Preamble
- The directory structure of a classic mailbox can contain certain special folders such as, for example, the one that stores emails…
- … once sent (= "Sent messages" or "Sent messages").
- … for a few days before their definitive deletion (= "Trash" or "Bin").
- Everything is already configured so that by default it is synchronized between the different messaging interfaces around the globe.
- If you wish to make adjustments for various reasons, sometimes linguistic, then refer to the guide below to modify these special folders:
- drafts
- sent messages
- bin
- archives
- This allows, in particular, to personalize the synchronization of these folders with IMAP clients such as Outlook, Mail iOS, Thunderbird, Spark, etc.
- Attention this does not change the email retention period placed in some of these special folders.
Access from the Infomaniak Web Mail app
Prerequisites
- Have a valid access to the Web app Mail Infomaniak (online service ksuite.infomaniak.com/mail) to which the email address is attached.
- Have permission to modify special folders: if you had been invited to Mail to manage your address, it is possible that the Mail Service manager has removed this right from their admin account.
To modify these special folders:
- Click here to access the Web app Mail Infomaniak (online service ksuite.infomaniak.com/mail).
- Click on the Settings icon ‍ at the top right.
- Check or select the relevant email address in the dropdown menu of the left sidebar.
- Click on Folders:

Access from the Mail Service
To access this option from a Mail Service:
- Click here to access the management of your product on the Infomaniak Manager (need help?).
- Click directly on the name assigned to the relevant product.
- Click on the relevant email address in the table that appears.
- Click on the tab Folders:

Configure special folders
For security reasons, folder management is confidential and reserved for users who have the password for the email address.
Select the desired folders to store by default your drafts, archives, sent messages, and your trash by clicking on the area to the right of each item:
This will display the list of folders already present in the directory of your mailbox (if necessary, create the desired folder in advance from Mail or an IMAP software).
To modify the default folders that receive spam and advertising messages & social network notifications you need to do it directly from the Spam Filter and Advertising Filter sections.
Alternative solutions for…
