If your Hotmail not Receiving/Sending emails on iPhone/Android/iPad, it's because of your contact form or server setup. Hotmail Toll-Free Phone Number: 1-325-238-8006. Here's an in-depth guide on how to solve Hotmail not receiving/sending emails on iPhone/android.
Before you begin
There are a few things to keep in mind and check:
When you make an iOS or iPadOS backup in iCloud or iTunes, it backs up your mail settings, but not your email. If you delete or change your email account settings, previously downloaded emails might be removed from your device.
Make sure that your device is connected to the Internet.
Check with your email service provider to find out if there's a service outage.
Check your email address and password
If the Mail apps asks you to enter a password for your email account, make sure that your password is correct. To check your email address and password, sign in to your email provider's website.
If you still get a username or password error, contact the email provider or system administrator.
Check Mail Fetch and Notification settings
By default, Fetch New Data settings are based on what's provided by your email service. If Push isn't available as a setting, your account will default to Fetch. These settings affect how your device receives email. To adjust these settings:
Go to Settings > Mail, then tap Accounts.
Tap Fetch New Data.
Choose a setting — like Automatically or Manually — or choose a schedule for how often the Mail app fetches data.
With iOS 11 and later, and iPadOS, Automatically is set by default. Your device will fetch new data in the background only when your device is charging and connected to Wi-Fi.
Make sure that your Notification settings are correct for the Mail app:
Go to Settings, then tap Notifications.
Tap Mail, then tap an email account.
Adjust your Alerts, Sounds, and Badges.
I hope these different techniques will be helpful!
