    Renaming a mailbox : risks and alternatives

    1. Reasons & Symptoms

    Renaming a mailbox may seem like a simple solution for tidying up or changing your identity, but this action is inadvisable and potentially dangerous. Here's why :

    • Data loss : Renaming can lead to data corruption or loss of access to e-mails, contacts and other information stored in the mailbox.
    • Synchronization problems : If you use multiple devices or email clients, renaming can disrupt synchronization and lead to inconsistencies between different platforms.
    • Application malfunctions : Some applications or services linked to your mailbox may no longer function correctly after a name change.
    Possible symptoms after mailbox renaming :

    • Unable to send or receive e-mails
    • Missing messages or contacts
    • Synchronization errors between different devices
    • Difficulties accessing services linked to your e-mail address

    2. Solution: Save, Delete and Create

    Rather than renaming your mailbox, we recommend adopting a more secure and efficient approach:

    1. Data Backup : Export all your e-mails, contacts and other important data to a PST file (Outlook) or equivalent format. This will enable you to keep a copy of your information in case of problems.
    2. Delete mailbox : Delete the mailbox you wish to rename. This step may vary depending on your e-mail provider, so be sure to follow the specific instructions.
    3. Create a new mailbox : Create a new mailbox with the desired name.
    4. Data import : Import your saved data (PST file or other) into your new mailbox. You'll be able to retrieve all your e-mails, contacts and other information.

    This method, although more time-consuming, guarantees the security of your data and avoids the risks associated with direct mailbox renaming.
