Hi @zeesh19791 ,
Can you share your image about your activity?

Have a view on this thread where similar error was discussed

Cheers @zeesh19791

Thanks but in that thread the reason is "Interface not registered’ and in my case it is “Element not found”
i didnt do any upgrade/update of ms office

No it’s actually about the same

It’s ok
But this error can possibly occur if there any recent update to Microsoft Office has corrupted the registry entry for the Outlook Application class.

Use repair tool to get this fixed

Even the above link did changes with registry to get this fixed

Cheers @zeesh19791
