Step 1: Head over to this page of Office support. The Microsoft Support and Recovery Assistant (SaRA) uses advanced diagnostics to report known problems and details about your Microsoft Outlook configuration. Windows 10 automatically downloads and installs important updates from Microsoft Server, but sometimes update installations get stuck or freeze when processing updates on Startup. To uninstall Dell SupportAssist, follow the instructions below. If the previous steps didn't fix the problem, and you're still seeing apps pending or stuck downloading, you can reset the Microsoft Store app using the Settings app. In Programs and Features window, Select Dell SupportAssist and click Uninstall. On the first screen, select Outlook, and then select Next.
