If you're having trouble with Outlook not responding, there are a few things you can try to fix the issue.
First, make sure that your computer meets the system requirements for Outlook. If you're using an older version of Outlook, you may need to upgrade to a newer one in order to avoid compatibility issues.
Next, check your internet connection. If you're using a dial-up connection, it's possible that the connection is too slow or unstable to support Outlook. Try switching to a different internet connection or contact your ISP for help.
If those two things don't solve the problem, try restarting your computer. Sometimes outlook just needs a fresh start in order to work properly again.
Finally, if none of these solutions work, you may need to uninstall and then reinstall Outlook on your computer. This will delete all of your current data and settings, so be sure to back everything up before proceeding.
