How to change the default time for delay delivery in Outlook?

When enabling the delay delivery option (the Do not deliver before option in the following screenshot) for an email in Outlook, the sending time is set to 5:00 PM by default. Supposing you are working late at night and don’t want others to know that you are working overtime. You need to enable the delay delivery option for your emails before sending them. After enabling the option, you need to change the default sending time manually. Otherwise, the email will be sent after 5:00 PM the next day. Is there any way to change this default delivery time?

This tutorial provides a VBA code to help you change the default time for the delay delivery option in Outlook.


Change the default time for delay delivery in Outlook with VBA code

You can apply the following VBA code to change the default time for the delay delivery option in Outlook.

In the following VBA code:

You can specify two times: the delay delivery time and the delay delivery option enabling time.

For example, you set the delay delivery time to 07:30 AM and set the delay delivery option to be enabled automatically after 5:30 PM. When you send an email during 07:30 AM - 5:30 PM, the email will be sent directly. If an email is sent during 5:30 PM – 07:30 AM, it will be scheduled to send after 07:30 AM the next day.

Please test the script as follows.

1. Launch your Outlook, press the Alt + F11 keys simultaneously to open the Microsoft Visual Basic for Applications window.

2. In the Microsoft Visual Basic for Applications window, double click on Project1 > Microsoft Outlook Objects > ThisOutlookSession to open the ThisOutlookSession (Code) window, and then copy the following code into this code window.

VBA code: change the default time for delay delivery in Outlook

Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
'Updated by Extendoffice & EWP 20230602
  Const xDelayTime As String = "07:30:00"  'The delay delivery time of emails
  Const xCompareTime As String = "17:30:00" 'The time to enable the delay delivery option
  Dim xMail As Outlook.MailItem
  Dim xWeekday As Integer
  Dim xNowTime As String
  Dim xIsDelay As Boolean
  Dim xRet1 As Integer
  Dim xRet2 As Integer
  On Error GoTo xError
  If (Item.Class <> olMail) Then Exit Sub
  Set xMail = Item
  xWeekday = Weekday(Date, vbMonday)
  xNowTime = Format(Now, "hh:nn:ss")
  xIsDelay = False
  xRet1 = StrComp(xNowTime, xDelayTime)
  xRet2 = StrComp(xNowTime, xCompareTime)
  If xRet1 = xRet2 Then
    xIsDelay = True
  End If
  If (xRet1 = -1) And (xRet2 = -1) Then
    xMail.DeferredDeliveryTime = Date & " " & xDelayTime
  Else
    If ((xWeekday = 5) And xIsDelay) Or (xWeekday = 6) Or (xWeekday = 7) Then
      xMail.DeferredDeliveryTime = (Date + (5 - xWeekday + 3)) & " " & xDelayTime
    ElseIf xIsDelay Then
      xMail.DeferredDeliveryTime = (Date + 1) & " " & xDelayTime
    End If
  End If
Exit Sub
xError:
  MsgBox "ItemSend: " & Err.Description, , "Kutools for Outlook"
End Sub

Notes:

1) You can change the delay time and the time to enable the delay delivery option in the following lines.
Const xDelayTime As String = "07:30:00"
Const xCompareTime As String = "17:30:00"
2) When sending an email on weekends, it will be scheduled to send after 07:30 AM on Monday.

3. Save the code and press the Alt + Q keys to close the Microsoft Visual Basic for Applications window.

From now on, when you send an email during 07:30 AM - 5:30 PM, the email will be sent directly. If an email is sent during 5:30 PM – 07:30 AM, it will be scheduled to send after 07:30 AM the next workday.

Hi

So useful! Can you add the option that if you are sending to people from within your organisation, this rule does not apply and emails are sent immediately?

Hi Crystal

This was just what I was looking for, it worked once, and I was very excited! Since then no matter what time of day, the emails send as soon as I click "Send". Any thoughts on what I've done wrong? I'd also love to be able to exclude 'high importance' flags.

Please ignore that request, seems it was to do with trust settings. Sorted now, thanks for the code!

I found that when you send an email on Sunday it is push to a week out as xMail.DeferredDeliveryTime = (Date + (vbSaturday - xWeekday + 2)) & " " & xDelayTime ends up with 8 days in the future instead of the expected one. As 7 (vbSaturday) - 1 (xWeekday on Sunday) + 2 is 8. This is my fix:
Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
'Updated by EWP 20230518
  Const xDelayTime As String = "07:30:00"  'The delay delivery time of emails
  Const xCompareTime As String = "17:30:00" 'The time to enable the delay delivery option
  Dim xMail As Outlook.MailItem
  Dim xWeekday As Integer
  Dim xNowTime As String
  Dim xIsDelay As Boolean
  Dim xRet1 As Integer
  Dim xRet2 As Integer
  On Error GoTo xError
  If (Item.Class <> olMail) Then Exit Sub
  Set xMail = Item
  xWeekday = Weekday(Date, vbMonday)
  xNowTime = Format(Now, "hh:nn:ss")

  xRet1 = StrComp(xNowTime, xDelayTime)
  xRet2 = StrComp(xNowTime, xCompareTime)
  If xRet1 = xRet2 Then

Hi Ehrin Pitts,

Thank you for the correction. I will check the code in the post and correct it.

This is a most useful piece of code, because it prevents me from disturbing people outside office hours.
However, I sometimes need to send an email outside normal hours and it is a nuisance to comment out the VBA code each time.
My suggestion is that if the "Importance" flage is set to high, then the mail will be sent immediately and not be delayed. Would it be possible for you to add such an exclusion in the code. (Still keeping the existing code, including the line with the xSenderAddress).

Hi Bernard,

The following VBA code helps to exclude the emails with a high importance flag. Please give it a try.
Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
'Updated by Extendoffice 20230410
  Const xDelayTime As String = "07:30:00"  'The delay delivery time of emails
  Const xCompareTime As String = "17:30:00" 'The time to enable the delay delivery option
  Dim xMail As Outlook.MailItem
  Dim xWeekday As Integer
  Dim xNowTime As String
  Dim xIsDelay As Boolean
  Dim xRet1 As Integer
  Dim xRet2 As Integer
  On Error GoTo xError
  If (Item.Class <> olMail) Then Exit Sub
  Set xMail = Item
  If xMail.Importance = olImportanceHigh Then Exit Sub 'Exclude emails with a high importance flag
  xWeekday = Weekday(Date, vbSunday)
  xNowTime = Format(Now, "hh:nn:ss")
  xIsDelay = False
  xRet1 = StrComp(xNowTime, xDelayTime)
  xRet2 = StrComp(xNowTime, xCompareTime)
  If xRet1 = xRet2 Then
    xIsDelay = True
  End If
  If (xRet1 = -1) And (xRet2 = -1) Then
    xMail.DeferredDeliveryTime = Date & " " & xDelayTime
  Else
    If ((xWeekday = vbFriday) And xIsDelay) Or (xWeekday = vbSaturday) Or (xWeekday = vbSunday) Then
      xMail.DeferredDeliveryTime = (Date + (vbSaturday - xWeekday + 2)) & " " & xDelayTime
    ElseIf xIsDelay Then
      xMail.DeferredDeliveryTime = (Date + 1) & " " & xDelayTime
    End If
  End If
Exit Sub
xError:
  MsgBox "ItemSend: " & Err.Description, , "Kutools for Outlook"
End Sub

Thanks for this macro. I often work late in the evenings or early in the mornings but don't want emails to be sent to my colleagues outside of normal working hours (for me, 08:00 to 17:45, which I've modified in the macro myself).

Is there a way to add an additional clause to the macro for sending emails, please? Currently, if I work early in the morning on a weekday (say 06:00, before the working day officially starts at 08:00) then the macro will delay sending until 08:00 on the following working day. I would rather the email was sent at 08:00 on the current working day. I tested your macro on a Thursday morning at 07:54 and the sending has been delayed until 08:00 on Friday, whereas I would want it to be sent on Thursday at 08:00.

Emails sent after the end of the working day should be sent at the start of the next working day, as you have written. Any emails sent at any time on Saturday or Sunday should be sent at the start of the next working day, again as you have written.

It's been a while since I've written anything substantial in VBA so I'm turning my head inside out trying to find the solution, with no success.

Hi Crystal,
I fixed the issue by closing the Outlook application and re-opening it after saving the VBA code. Thank you for this!

Hi Crystal, I followed your instructions and enabled macros, but the emails are still sending as soon as I click "Send".

I have Outlook version 2101 (Build 13628.20274).

1. I did not modify any variables in the code, so it is saved just as you have instructed for "ThisOutlookSession".
2. It is the only code in "ThisOutlookSession".
3. The current time is 3:19 AM Eastern Time, so I would expect the emails to be delayed upon clicking "Send" since I am attempting to send an email during the time period of 5:30 PM - 07:30 AM.
4. I verified the Macros are enabled.

Is there anything else you can suggest that could cause this macro not to work? Thank you

From the tutorial: "From now on, when you send an email during 07:30 AM - 5:30 PM, the email will be sent directly. If an email is sent during 5:30 PM – 07:30 AM, it will be scheduled to send after 07:30 AM the next workday."

This is a longshot - but i have work and personal accounts in Outlook. Is there a way to set this only for certain accounts?

Hi Ann,
The following VBA script may help. Please give it a try.
In this line: xAccount = "Your email account", please replace the text "You email account" with your own account. For multiple accounts, please use a semicolon ";" to separate them.

Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
'Updated by Extendoffice 20230117
  Const xDelayTime As String = "07:30:00" 'The delay delivery time of emails
  Const xCompareTime As String = "17:30:00" 'The time to enable the delay delivery option
  
  Dim xMail As Outlook.MailItem
  Dim xWeekday As Integer
  Dim xNowTime As String
  Dim xIsDelay As Boolean
  Dim xSenderAddress As String
  Dim xAccount As String
  On Error GoTo xError
  If (Item.Class <> olMail) Then Exit Sub
  Set xMail = Item
  xSenderAddress = ""
  xSenderAddress = xMail.SendUsingAccount.SmtpAddress
  xAccount = "Your email account"  'Specify your email account here and use ; to separate different accounts
  If VBA.InStr(xAccount, xSenderAddress) = 0 Then Exit Sub
  xWeekday = Weekday(Date, vbSunday)
  xNowTime = Format(Now, "hh:nn:ss")
  xIsDelay = False
  If StrComp(xNowTime, xDelayTime) = StrComp(xNowTime, xCompareTime) Then
    xIsDelay = True
  End If
  Debug.Print xIsDelay

    xMail.DeferredDeliveryTime = (Date + (vbSaturday - xWeekday + 2)) & " " & xDelayTime
