How to Fix Cannot Add gov.uk Email Account to Outlook 365
Question details
The user is unable to add an IONOS-hosted gov.uk email account to Outlook 365, despite the account functioning correctly on Android.
- Product
- Microsoft Outlook 365
- Device & OS
- Windows
- Scenario
- Attempting to configure and add a gov.uk email account to the Outlook 365 desktop client using IONOS server settings.
- Observed behavior
- The account fails to add, and old account entries appear in Outlook's folder pane but are missing from Account Settings, indicating a damaged or corrupt Outlook profile.
Verify your exact IONOS mail host server names, port numbers, and encryption settings before proceeding. Ensure Outlook is completely closed and consider creating a system restore point if you plan to edit the Windows Registry.
Create a New Outlook Profile via Control Panel
Creating a new Outlook profile is the safest way to bypass account corruption and cleanly configure your gov.uk email address.
When an Outlook profile becomes corrupted, it can cause 'ghost' folders to appear without being manageable in the account settings. Creating a fresh profile allows Outlook to establish a clean connection to your IONOS mail server.
Click the Start menu, type 'Control Panel', and open it. Change the view to Large Icons and click on 'Mail (Microsoft Outlook)'.
Click the 'Show Profiles...' button. Click 'Add', enter a name for your new profile (e.g., 'GovUK Account'), and click OK.
In the Add Account window, enter your gov.uk email address and password, or select 'Manual setup' to input the specific IONOS IMAP/SMTP server settings. Follow the prompts to finish the setup.
Back in the Mail window, select 'Always use this profile', choose your newly created profile from the drop-down menu, and click Apply and OK.
Remove the Corrupted Account via Registry Editor
Manually delete the residual subkey for the broken account from the Windows Registry to clean up the existing Outlook profile.

Frequently Asked Questions
Why does my gov.uk email account show in the Outlook folder pane but not in Account Settings?
This is a classic symptom of a corrupted Outlook mail profile. The interface caches the folder structure, but the backend account configuration is broken or missing, creating a 'ghost' account.
What are the correct IONOS server settings for Outlook?
Typically for IONOS, the incoming server is imap.ionos.co.uk (Port 993, SSL/TLS) and the outgoing server is smtp.ionos.co.uk (Port 465, SSL/TLS). Always verify the most up-to-date settings on the official IONOS support page.
Will creating a new Outlook profile delete my old emails?
No. When using IMAP or Exchange, your emails are safely stored on the mail server. Creating a new profile simply re-establishes the connection, and your emails will synchronize back to your computer automatically.
