How to Fix Classic Outlook Stuck on Loading Profile in Microsoft 365
Question details
The user needs to resolve an issue where the Classic Outlook application hangs indefinitely during startup while attempting to load the user profile.
- Product
- Microsoft Outlook (Classic), Microsoft 365
- Device & OS
- not provided
- Scenario
- Launching Classic Outlook to access emails after configuring an account in Microsoft 365.
- Observed behavior
- Classic Outlook remains completely stuck on the 'Loading Profile' screen, even though other Microsoft 365 applications like Word, Excel, and the New Outlook open normally.
Before creating a new Outlook profile, ensure you export any IMAP folders marked 'This computer only' to a PST file, as these folders will not automatically transfer to a new profile.
Create a New Outlook Profile
Creating a new Outlook profile bypasses corruption in the current profile that causes the application to hang on the loading screen.
The most common cause for Outlook getting stuck on the 'Loading Profile' screen is a corrupted profile registry or a syncing error with the configured email accounts. By creating a fresh profile, you force Outlook to establish a new connection to your mail servers without carrying over the broken configuration.
Close Outlook completely. Open the Windows Control Panel, change the view to 'Large icons' or 'Small icons' in the top right, and click on 'Mail (Microsoft Outlook)'.
In the Mail Setup dialog box, click on the 'Show Profiles...' button to see all currently configured Outlook profiles on your system.
Click the 'Add...' button, type a descriptive name for your new profile (e.g., 'NewProfile'), and click 'OK'.
Follow the Auto Account Setup wizard to enter your email address and password. Once the account is successfully configured, click 'Finish'.
Back in the Mail dialog box, select the option 'Always use this profile', choose your newly created profile from the dropdown menu, and click 'OK'. Restart Outlook.
Run Outlook Executable Directly or in Safe Mode
Use this method to determine if the issue is caused by a faulty desktop shortcut or a conflicting third-party add-in.

Frequently Asked Questions
Why does Classic Outlook get stuck on Loading Profile?
This issue is typically caused by a corrupted Outlook profile, a stuck process in the background, conflicting COM add-ins, or navigation pane corruption. It can also happen if Outlook is struggling to connect to an IMAP server like Yahoo Mail or an Outlook.com alias.
How do I backup IMAP folders marked 'This computer only'?
Before creating a new profile, you must open Outlook (if possible via Safe Mode). Go to File > Open & Export > Import/Export. Select 'Export to a file', choose 'Outlook Data File (.pst)', and select the specific folders marked 'This computer only' (such as Calendar or Contacts) to back them up to your local drive.
Will reinstalling Microsoft 365 fix the Outlook Loading Profile error?
Reinstalling Microsoft 365 usually does not resolve this specific issue. This is because your Outlook profile configurations and data files are stored in the Windows Registry and the AppData folder, which persist even after the application itself is uninstalled and reinstalled.
