Hi @Arush Verma ,
From the image you offered above, seems we could not get the accurate information about your Outlook version. To further confirm your issue, please check your Outlook version via File > Office Account > About Outlook, for example like below:
If there is no version number there, you could get your Outlook version number by clicking the "About Outlook" button and you will get information like below:
Then, you could try to compare with your Office version and see if there is any difference.
As I know, the Outlook desktop client usually will not update separately. Outlook is a program included in the Office suite and will be upgraded along with the Office version. Maybe you could try to upgrade your Office via Outlook > File > Office Account > Office Updates > Update Now and see if the issue could be resolved.
If the issue continues, please try repairing your Office installation.
