Part 1: Why is Outlook delayed delivery not working?

Outlook is one of the finest email programs for Windows 10. Delayed delivery is a lesser-known capability of Outlook that allows you to plan emails to be sent at a future time and date. Here are some reasons why Outlook Delay Delivery is not working on your Windows PC.

Now you know the reasons for outlook 365 delayed delivery not working. Thus, here I will discuss the proven solutions to fix this problem shortly. So, here we go!

Fix 1- Verify rules for delaying the delivery

Outlook offers delay delivery settings and custom rules as the two options to delay email delivery. The original Delay Delivery option might not function or result in a conflict if you have already implemented a rule to delay an email delivery.

For instance, you have fixed the delay delivery time for 10 minutes from the current time. On the other hand, you have a custom postponed delivery rule set to 15 minutes applied to your present email. With such a situation, there is a higher probability you’ll see a delayed delivery outlook not working

To rescue this, I have three options, such as:

  • Customize the existing rule
  • Customize the email
  • Delete the rule

Here’s how you can do this practically-

Step 1 Open the file menu and choose the manage rules and alerts option.

Step 2 Choose the email rules option and select the change rule, and edit rule settings.
