Hi Bilal, 

Thanks again for your reply, however, as I mentioned in my previous reply, it is not available to doing so within Exchange online server for security reasons. And also, for the same reason, you cannot change this limit on your side. We sincerely appreciate if you can understanding for this.

Given this situation, if you have other Office license to install Outlook desktop client on your PC, then I'd like to recommended you have a look at below article to see if the feature delay sending email messages can meet your demands: 

Delay or schedule sending email messages

Your understanding and cooperation will be highly appreciated.

Best regards,
