It sounds like you are experiencing performance issues with Microsoft Outlook, which can be caused by various factors, including server issues or local network problems. Here are some steps you can take to troubleshoot and potentially resolve the issue:
- Check Service Health: Sign in to the Microsoft 365 portal using your administrator credentials and check the service health section to see if there are any ongoing issues affecting Outlook.
- Install Updates: Ensure that you have the latest updates for Outlook installed. This can help resolve performance issues.
- Run Diagnostics: Use the Classic Outlook Advanced Diagnostics troubleshooter to create a detailed configuration report. This can help identify specific issues affecting your Outlook performance.
- Disable Skype for Business Integration: If you are using Skype for Business Online, try disabling its integration with Outlook, as it may impact performance.
- Check Network Issues: Investigate any local network issues that may be affecting your connection, such as problems with your proxy server, firewall, or Internet service provider.
If the issue persists after trying these steps, you may want to reach out to Microsoft Community for further assistance.
