Dear Colleague,

I hope this email finds you well. I apologize for the inconvenience caused by the unexpected work-related commitment on Thursday, but I understand that things came up with a client and needed to be addressed immediately.

To avoid any confusion, I would like to request that we move our Thursday 2 pm review to 4 pm instead. This will give us enough time to finalize the work and ensure that everything is on track for the client's project. If this is possible, please let me know by Friday morning.

Thank you for your prompt attention and attention to our team's needs. I look forward to hearing back from you regarding the changes. If you have any questions, please do not hesitate to reach out to me.

Best regards,

Dear Colleague,

Thank you for your email. As I mentioned, I am unable to do 4 pm on Thursday, but I can certainly do 3 pm on Thursday or 10 am on Friday. If the meeting is not essential, and the client's needs are not urgent, I believe this time slot would work well. Please let me know if there is anything else I can assist you with. Once again, thanks for your understanding and cooperation. Best regards,
