由于工作太忙原因参加不了会议，如何用英文委婉写拒绝信？

Dear ×××：
At first I must thank you for your kindly meeting inviting . However , I feel terribly sorry for my not being able to attend it because of my work occupying my time. So can you help to send me the meeting minutes after your finishing it , and I will follow the requirements declared during the meeting. I wonder whether what I mentioned above is O.K or not. If not , I will reset my work schedule , and spare my time to attend this meeting. If so , thank you in advance.

Sincerely

Thank you for inviting me to the meeting,I 'd like to go very much,but it is pity that I am so busy with my work for the moment and I cannot go.I feel sorry very much,and I hope that the meeting goes well.
