Why? Do you have any wallet recovery services which have tested by trusted users here? Otherwise why you should ask to give you access of him email? You aren't enough trustworthy on the forum. Also OP found where his bitcoin was exist here. At least you should read the page where you are going to reply.

@OP don't handover your account credential to any untrusted person. You might get scam simply by that way. Just participate on open discussion here and find some trusted users who could really help you. Perhaps so any scammers would send you PM, but please don't share your account credential with all of them. Mention the person here so we might see if he is trustworthy.
