    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.

    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.
