How can i make subject bold in mail vba code

In VBA, you can use the Format method to make the subject of an email bold. Here's an example code:

Dim olApp As Object
Dim olMail As Object

Set olApp = CreateObject("Outlook.Application")
Set olMail = olApp.CreateItem(0) ' 0 = olMailItem

olMail.Subject = "**Your Bold Subject**" ' Use double asterisks to make the subject bold
olMail.Body = "This is the body of the email"

olMail.Send

Alternatively, you can use the Font property to set the font style of the subject to bold:

olMail.Subject = "Your Subject"
olMail.Subject.Font.Bold = True

Note that the second method will make the entire subject bold, including any spaces or punctuation. If you only want to make certain parts of the subject bold, you can use a combination of the Format method and the Font property:

olMail.Subject = Format("Your **Bold** Subject", "Your [b]Bold[/b] Subject")

This will make the word "Bold" bold, while leaving the rest of the subject in regular font.
