    I'm afraid that you're at a wrong place. This forum is about Microsoft Dynamics, not Microsoft Office. Try the Outlook forum on Microsoft Tech Community.

    Hi, 

    Outlook running slowly can be caused by several factors, but there are effective steps you can take to improve performance:


    ⚙️ Troubleshooting Tips

    • Disable unnecessary add-ins: File → Options → Add-ins → Manage COM Add-ins
    • Archive or delete old emails: Large mailboxes slow things down.
    • Update Outlook: File → Office Account → Update Options
    • Repair your Outlook profile: Control Panel → Mail → Show Profiles → Repair
    • Clear cache and temp files: Especially useful for shared mailboxes/calendars.
    • Check antivirus software: Some may interfere with Outlook.
