Lost e Mail I have composed

I have just spent a long time working on an e mail. It has now just disappeared, how can I get it back? Thanks to anyone who can help.

Hi Jan,

Not knowing why it disappeared, look in Drafts under the account or else look in Drafts under 
Local Folders - if enabled…

To Enable/Disable 
Menu > Tools > Settings >

I have looked in all the other folders - no luck!

Have you looked at the account on the server under Drafts?

Also -Have you done a Search in eM Client with Subject name or other relevant criteria?

Was it inadvertently Sent?
Is it in Outbox ? either under the account or in Local Folders ?
