Need to switch back to older version

Need to switch back to older version

Hi All,

I really don't like this new version of zoho email, it looks messy and things are not right in place. I don't know what you feel but its my personal impression.

I don't find any option right on top of the right side. seems its been default mail interface which I really don't want.

Please if anyone can help me to switch back to older version, that really looks fantastic and user friendly.

Please help
