Solution 1Recommended

Run Outlook in Safe Mode and Disable Faulty Add-ins

Starting Outlook in Safe Mode allows you to bypass customizations and add-ins to identify if a third-party extension is causing the Event ID 1002 hang.

Third-party add-ins are a common cause of Outlook freezes. Safe mode loads Outlook without these extensions, helping you isolate the problematic software.

1
Open the Run dialog

Press the Windows key + R on your keyboard simultaneously to open the Run dialog box.

2
Launch Outlook in Safe Mode

Type 'outlook.exe /safe' into the text box and press Enter or click the OK button.

3
Access Add-ins settings

If Outlook opens successfully without hanging, navigate to the File menu in the top-left corner, click on Options, and then select Add-ins from the left sidebar.

4
Disable Add-ins

At the bottom of the window, ensure 'COM Add-ins' is selected in the Manage dropdown and click 'Go...'. Uncheck all add-ins in the list and click OK. Restart Outlook normally to see if the issue is resolved.

Run Outlook in Safe Mode and Disable Faulty Add-ins
Isolating the Add-in: If Outlook runs smoothly after this process, re-enable the add-ins one by one and restart Outlook each time to identify the specific add-in causing the crash.
