How Do I Apologize to My Coworker?
A letter is a good way to state the apology. However, if you need to do the apology in person, just do it by visiting the coworker in their house or calling their cell phone. It seems more personal and intense compared to a letter.
How Do You Apologize for a Mistake Professionally?
The only way to professionally apologize for a mistake is to admit that you are wrong. Other than that, you will just sound like you put the blame on someone else and it does not seem very professional.

Dear Rachel,
This is my formal letter to ask for your apology. I know that I had made a massive mistake yesterday by not sending the right file for your final presentation in front of the board of the direction. It has caused chaos in the presentation and got you in trouble.
I am terribly sorry for yesterday’s unfortunate event. I thought I have checked the file before I sent them to you. Apparently I did send the wrong file. With this letter, I hope you can forgive me for what I did and I take full responsibility for it.
This letter is going to be sent to the human resources department as well so that they know if anyone has to be responsible for any bad outcome from yesterday’s event, it has to be me. Once again, I am very sorry for what happened yesterday.
Thank you.
Sincerely,
Thomas Throne
Those are some of the things you have to understand about the letter. Before making any apology to the coworker, make sure that you have do the right thing to mend the situation. Probably before even sending this apology letter to coworker, you have tried to apologize to the coworker in person.
