1. Open the Mail app, then click on the Settings icon (it looks like a gear cog) in the bottom left corner of the screen.
2. A menu will appear, from which you need to select Manage accounts, then click on the email address you want to adjust.
3. A new window will open with the settings for that particular account. Under the text field entitled Account name you’ll find the option to Change mailbox sync settings. Click on this.
4. Now, at the top of the next box there is a drop-down menu available under the Download new email heading. Microsoft defaults to the rather nebulous ‘as items arrive’, but we recommend you choose a more measurable time period instead.
The ‘as items arrive’ option will keep your PC on its toes, constantly looking out for new messages, but this can also add processes and a slight drain on the battery of a laptop. If your needs are not so instant, then the ‘every 15 minutes’ or even ‘every 30 minutes’ might be the route to go down.
When you’re happy with the new frequency, click the Done button and you should see a marked improvement in the regularity of your messages.
