I was employed by a company for nearly 18 years. My boss accused me of manipulating an email with intent to deceive him into thinking that I sent the email earlier than I did. I used IBM Lotus Notes, on a large corporation's private server. I had sent an original email to a customer on 2/21/16. On 2/28/16 My boss requested that I forward him the email proving that it was sent. I went into my sent folder and forwarded the email. He is claiming that the email i provided as he requested originated on 2/28/16, which was the day I sent it to him, and that I falsified the 2/21/16 date, which was on original. In Lotus Notes, there is a pink line of text above the original email's header that says forwarded by so and so on 2/21/16. He said that this date should have been 2/28/16 and that I somehow changed it. I've never had my integrity questioned before. He would not tell me what sort of proof he had that I did this, just said that he had the home office check it out. How is this possible?
