请帮忙翻译一下，大概意思就行，但语气要客气点的，谢谢。

由于那天早上我们也有其他客户要过来，所以你提出的会议的时间我们不能满足，请尽量按原定会议时间谢谢。

I'm really sorry to suggest you follow the original schedule for the meeting as we're afraid we cannot meet the new one due to the presence of other customer the same day, sincerely hope to get your kind understanding and cooperation.

We regret to inform you that we are not able to comply with the meeting schedule that you had suggested, this is because we have to deal with other clients who would be coming on morning of the same date that you proposed. So we have no choice but to request that we maintain the original time and date for our meeting. Thank you for your understanding.

Since we have other clinets come over that morning, the time you proposed for the conference is hard to meet, pls try to follow the orginal time thank you.
