This is of some importance to me and I greatly appreciate any assistance on the matter. I'm trying to locate an e-mail sent to me from an employer. I believe I received it between the 16th September and the 20th September. I'm 100% certain that I didn't delete it and am gobsmacked as to where it has gone. 

I've looked through all the folders to try and find it and can't. I looked in the deleted folder and don't see any retrieve e-mail option so I can't retrieve it from the deleted e-mail box if it has been deleted. 

I must say that I need a speedy resolution to the matter as it was an invitation for a job and I need to accept the invitation by today 20th September. 

I believe that this is not the first time this has happened and would greatly appreciate any ideas on the matter or solutions. 

Regards, 

Phil.
