Before you jump straight to configuration fixes, let’s check if the basics are working fine.

1. First and foremost, ensure your system is connected to a strong and stable internet connection.
2. Then, try opening websites or stream content to confirm the stability of the network.
3. Now, if the internet connection turns out to be inconsistent or slow, restart your router or simply switch networks.

Now that we have ensured strong network stability, let us move further and check out other solutions.

Some mail servers require authentication for outgoing email messages. Here’s how to enable that:

1. First, open Account Settings in MS Outlook
2. Then, click “More Settings” and go to the “Outgoing Server” tab
