The Zimbra messaging service associated with @aliceadsl.fr addresses remains active for thousands of former Alice ADSL subscribers, now managed by Free. Accessing this email account does not pose any particular technical difficulties, but several less visible parameters deserve specific attention: the policy for deleting inactive accounts, IMAP synchronization on mobile, and Zimbra’s recent GDPR compliance.
Inactive Alice Zimbra Accounts: The Risk of Deletion After 24 Months
Free applies a policy of deactivating email addresses linked to former Alice ADSL subscriptions when no connection is recorded for an extended period. This threshold, set at 24 months of inactivity, does not appear in any public access guide dedicated to Zimbra Alice.

The direct consequence is the permanent loss of stored emails, contacts, and calendars associated with the account. For users who only use this address occasionally (receiving administrative emails, old recovery account), the risk is real.
Three actions can help maintain an active account:

- Log in to the Zimbra webmail via zimbra.aliceadsl.fr at least once every six months, even without sending a message
- Set up a mail client (Thunderbird, Outlook) using IMAP so that regular synchronization is counted as activity
- Set up an automatic forward to a Gmail address or another, which generates incoming activity on the Alice account
A detailed guide helps better understand how to access the Alice Zimbra messaging service and check that the account remains functional.
IMAP and SMTP Settings to Configure Alice Zimbra on Thunderbird, Outlook, or Mobile
Configuring a third-party mail client remains the most reliable way to use an aliceadsl.fr address on a daily basis, especially for those who do not wish to go through the Zimbra webmail for every check.
| Parameter | Incoming Server (IMAP) | Outgoing Server (SMTP) |
|---|---|---|
| Server Address | imap.free.fr | smtp.free.fr |
| Port | 993 (SSL/TLS) | 465 (SSL/TLS) |
| Authentication | Full address @aliceadsl.fr | Full address @aliceadsl.fr |
| Encryption | SSL/TLS | SSL/TLS |
On Thunderbird, automatic detection rarely works with Alice addresses. You must manually enter the parameters in the “Manual Configuration” section when adding the account.
On Outlook (desktop version or mobile app), the IMAP protocol should be preferred over POP3. POP3 downloads messages locally and deletes them from the server, which can inadvertently trigger the inactivity counter if no messages remain stored on the Zimbra side.
Mobile Synchronization and Observed Limits
User feedback on specialized forums reports a less smooth IMAP synchronization at the end of the day on mobile compared to solutions like Outlook 365. This slowdown, linked to peak usage of Free’s servers, primarily affects the reception of new messages and the updating of folders.
To limit this inconvenience, setting the synchronization interval to 15 minutes (instead of “push”) in the mobile mail client settings reduces server load and stabilizes the connection.
Zimbra Update April 2026: GDPR Consent and Data Sharing
Zimbra Inc. rolled out an update in April 2026 introducing granular consent tools for sharing calendars and contacts. This development, related to compliance with GDPR 2.0, directly affects Alice Zimbra users.
Specifically, sharing a calendar or address book with another Zimbra user now requires explicit validation from both parties. Before this update, sharing was active by default as soon as a link was generated.
This change has practical implications for small organizations that used Alice Zimbra as a collaborative tool: each sharing invitation must be accepted individually, adding a step to the workflow. The webmail interface now displays a consent management banner accessible from the account settings, under the “Sharing and Privacy” tab.
Migration from Alice Zimbra to Gmail or a Sovereign Messaging Service
The Arcep report from February 2026 on sovereign messaging services indicates a growing migration of Alice Zimbra users to independent alternatives, motivated by the desire to reduce dependence on Free’s infrastructure.
Two trajectories are emerging among users leaving Alice Zimbra:
- Migration to Gmail or Outlook.com, facilitated by the native IMAP import of these platforms, which retrieves all folders and messages in a few hours
- Transition to sovereign solutions like Tchap (the French state’s messaging service) or independently hosted Zimbra instances, chosen for their resilience against unilateral decisions by an operator
- Maintaining the Alice account alongside a new address, with automatic forwarding configured in the Zimbra webmail settings to avoid losing any incoming messages
Exporting Contacts and Emails Before Migrating
The Zimbra webmail allows exporting contacts in CSV format (compatible with Gmail and Outlook) and emails in EML format from the “Preferences > Import/Export” menu. This native feature avoids the need for third-party software.
For a complete export including folder structure, Thunderbird configured in IMAP remains the most suitable tool: simply drag and drop the Zimbra folders to a local account, then re-import them into the new mail service.
The Alice Zimbra messaging service remains functional and free as long as the account is regularly accessed. The most underestimated point of vigilance remains this 24-month inactivity window, after which recovering the account and its content becomes impossible with Free support.
