Hi Bhanu,
Do you search in Outlook? What's the detailed version information of both Office and Windows?
Could we know what steps have you tried already so far?
I’ve noticed that there was a known issue that this error could happen due to some Windows updates. Please check the detailed information in
this link under Issue #5 section to see whether this is the case for you.
Any updates, please feel free to post back.
Regards,
Perry
