Create a New Outlook Profile via Control Panel

Creating a new Outlook profile can bypass corrupted configuration files and restore proper synchronization with the email server and your phone.

A corrupted Outlook profile is a common cause of synchronization issues between devices. By confirming your mailbox works online and setting up a fresh profile, you can re-establish the connection without losing data.

1
Verify Web Access

Open a web browser and sign in to your account at https://outlook.live.com/mail/0/ to confirm that your mailbox is active and accessible online.

2
Open Mail in Control Panel

On your Windows computer, open the Control Panel, change the view to Large or Small icons, and click on 'Mail'.

3
Add a New Profile

Click the 'Show Profiles' button, then click 'Add'. Enter a name for your new profile and click OK.

4
Complete Account Setup

Enter your email address and credentials in the prompt to configure the new profile, then wait for Outlook to connect and sync from the server.

5
Transfer Local Data (If Needed)

If the new profile synchronizes correctly, export any missing local data from the old profile into a PST file, then import it into your new profile.

Frequently Asked Questions

Will I lose my emails if I create a new Outlook profile?

No, creating a new profile simply reconnects your computer to the mail server. Your emails stored on the server will automatically download to the new profile. Local-only data can be preserved by exporting to a PST file.

How do I export my Outlook data to a PST file?

In Outlook, click on File > Open & Export > Import/Export. Choose 'Export to a file', select 'Outlook Data File (.pst)', and follow the on-screen instructions to back up your data.

Why is my phone syncing but my computer is not?

This usually indicates that the Outlook profile on your computer is corrupted, the application is outdated, or it has been disconnected from the Exchange server. Rebuilding the profile often resolves this.
