Hi Satish,

Thank you for sharing. We've gone through each of your errors, and would have recommended the system file checker and DISM for the first one. Your Outlook notification suggests you might have a third-party add-in that may be provoking that problem, so I'd suggest disabling any unnecessary add-ins to see if that helps. The third one, yeah, we'd have recommended rebuilding the index as well. That said, however, we'd recommend pulling a memory dump file and sharing it with your customer success account manager and/or our support team, as these errors in combination you're seeing will require some digging to find the culprit.
