    I cannot switch back to my old ISP as it was an webmail on a shared hosting which is expired now.

    @Alina-Le;
    This isn't a local issue but a service issue since configuring an IMAP account in New Outlook triggers it to be synced to a Cloud Mailbox. The connection settings are saved there and can't be altered nor reset by the end-user.

    It seems like you've gotten yourself stuck in an unrecoverable state. I'm currently in contact with the Outlook Team to determine how to proceed. Do you perhaps have a Microsoft 365 license associated with that account? In that case, opening a support case would be te way forward to get the Cloud Mailbox for that IMAP account reset.

    As an interim solution, you could use Classic Outlook instead, as that doesn't use a Cloud Mailbox for IMAP accounts. However, in order to start with New Outlook again, a service level reset would still be needed.

    No unfortunately I don't have a office 365 licence and my system came with an student's edition of office so I don't have a classic Outlook subscription. So I'm relying on Outlook app could please help me with a service level reset?

    Hello Sanket, 

    I appreciate you posting to Microsoft Community! 

    As your description, it sounds like that your Outlook is still trying to use your old email provider’s address to connect, even though you’ve switched to a new one. It’s like Outlook is stuck remembering the old way and won’t let you change it. 

    To fix this, we need to help Outlook “forget” the old settings and set it up fresh with the new provider. 

    Option 1: Remove and Re-add the Account 

    1. Open New Outlook for Windows.
    2. Go to Settings (gear icon) > Accounts.
    3. Locate the problematic account and remove it.
    4. Restart Outlook.
    5. Go back to Settings > Accounts and add the account again, using the new IMAP server.

    Option 2: Clear Cached Account Data

    If removing the account doesn’t work, try this: 

    1. Close Outlook completely.
    2. Open Windows Settings > Apps > Installed Apps.
    3. Find New Outlook and click Advanced Options.
    4. Click Reset to clear cached data (this won’t delete emails stored on the server).
    5. Reopen Outlook and reconfigure the account.

    Option 3: Use Mail App Temporarily 

    If New Outlook continues to block the change, you can: 

    • Use the built-in Mail app on Windows to access your IMAP account.

    Option 4: Switch Back to Classic Outlook (Temporarily) 

    1. Open New Outlook.
    2. Go to the Help menu > Switch to Classic Outlook.
    3. Re-add your account using the new IMAP server (imap.hostinger.com).
    4. Once everything works, you can switch back to New Outlook if needed.  Image Or in the New Outlook interface, You can look for the toggle switch in the upper-right corner labeled “New Outlook.” and turn off it.   Image

    Hope it will be helpful for you. Please let me know if you still have any questions or concerns. 

    Best Regards,
