Assuming you have been following the last three sections, are connected to the internet and have opened the Windows 10 MAIL App (program); I will now explain how e-mails are received, both automatically and manually.

Normally you wait for e-mail to arrive automatically because your e-mail client (e-mail program), such as Mozilla Thunderbird, Microsoft Outlook 2016 and Windows 10 MAIL App, have a timer function whereby they automatically check for new, incoming, e-mails every 5 Minutes for example. However, sometimes you need to manually check for e-mails, especially if you are waiting for an important e-mail to arrive. In those cases you can override the automatic check function by clicking on the SYNC (Synchronise) button, located at the top of the Folder Views / Conversation Panel window pane - The window pane on the left side of the main Windows 10 MAIL App window.

Fig 1.0 - Click on the SYNC (Synchronise) button to check for new e-mail

When you click on the SYNC button the status bar at the bottom of the Folder Views / Conversation Panel window pane will update its information, from 'Last updated 1 hour ago' to Syncing...' for example, to let you know new e-mails are currently be checked for. The 1 Hour, by the way, would be because you have just opened the Windows 10 MAIL App or have been offline for 1 hour. Normally this would state '5 minutes ago' or something similar. It also depends on the synchronise setting (see below).

If, after synchronising, there are no new e-mails the message in the middle of the Folder Views / Conversation Panel window pane will state 'We didn't find anything to show here' and the status bar will state 'Up to date' (Fig 1.2 above). However, if one or more e-mails were found (retrieved from the ISP's (broadband provider's) e-mail server (e-mail computer) it/they will be listed in the Folder Views / Conversation Panel window pane whereby the first one will be opened. If it does not automatically open just click on its listing to open it (view the actual e-mail message).

Fig 1.3 - A new e-mail has arrived from Denise Oakdale

In the example above Denise Oakdale has replied to the e-mail I sent her yesterday at 12:40 pm and almost 2 hours later she has replied to the second e-mail (below) I sent her yesterday at 6:40 pm. To open that new, second, e-mail I just need to click on its heading (small preview listing) within the Folder Views / Conversation Panel window pane (Fig 1.5 below).

Fig 1.5 - To open the new, second, e-mail from Denise Oakdale I just need to click on its small preview listing

The new, second, e-mail has two attachments (two files attached it), which can be opened by double clicking on each one or by downloading them first and then opening them (discussed in the next section).


In the next example Denise Oakdale has sent another e-mail, which has come from her replying again to the second e-mail I sent to her. So instead of creating a new e-mail, she opted to click on her Yahoo REPLY button while reading my second e-mail in order to reply to it. In other words, she has replied twice to my second e-mail; which is quite normal and legal.

When I receive that second reply e-mail it is catalogued as a "Conversation", because Denise and I are classed as continuing with the same e-mail. Or put another way, replying to each other using the same original e-mail conversation. Hence the term "Conversation". Anyway, what this means it that this second reply e-mail (and any e-mails thereafter within the same conversation) will be marked in the Folder Views / Conversation Panel window pane with a collapsible/expandable listing; denoted by the small blue triangle button to the left of the conversation listing.

Fig 1.6 - A second e-mail has arrived within the same conversation

To open an e-mail that is within a conversation (conversation listing) simply click on the listing or click on the small blue triangle. Either way will expand the listing and preview the latest conversation (latest unread e-mail within the conversation). Technically you are only previewing the first part of the e-mail. Meaning, if the e-mail is longer than in the example below and/or has many attachments (many files attached to it) you would need to scroll down the e-mail message to see all of the e-mail.

Fig 1.7 - Look closer at the information given out within the preview listing (e-mail header)

The listing gives important information about each received e-mail. For example: The word RE: has been added to the title (subject) of the original e-mail. This is to let you know it is a reply. Think of RE as REply, in REsponse to or in REference to. The time in the listing (i.e. 10:29) is the time the person sent you the e-mail and NOT the time you received it. The thick blue vertical line to the left of a particular e-mail means that e-mail has not been read (clicked on) yet; Hence another reason why I talked about 'technically only previewing an e-mail' above. And the number in brackets to the right of the listing denotes the number of separate e-mails received within the conversation, and NOT the actual number of replies.

Regardless of conversation or not, another thing to note is that underneath the e-mail message is the previous reply/replies. This is so that you can remember what the other person was talking about last time. In today's society of receiving many e-mails, sending many e-mails and replying to many e-mails it is quite easy to forget what has been said and by whom; hence the beauty of Conversation listings (grouped, related, e-mails).


When you sign up for an e-mail account with Yahoo, Outlook or an Internet Service Provider such as TalkTalk for example they sometimes impose an e-mail storage limit on that e-mail account, especially if they are offering that e-mail account for FREE or as Pay-As-You-Go (P.A.Y.G). The limit is usually anywhere from 5GB to 25GB but can be much larger depending on the individual companies (service providers). Saying this, a lot of companies now offer "Unlimited" storage space.....

Nothing wrong with that you might be thinking, but what you have to remember is that there will normally be a limit on the e-mail size you can send or forward, and more precisely a limit on the amount of Bandwidth (Download/Upload Usage).

This means for example; If you have a collection of 10 e-mails to be received from Yahoo into the Windows 10 MAIL App, of say 2 GB per e-mail (including file attachments), some ISPs might not allow a 2 GB e-mail to be received (downloaded) for whatever reason(s). On the flip side of this the Windows 10 MAIL App currently has a limit of 1 GB for sending and receiving e-mail. So the reverse would be true - You could not send a file of 3 GB for example from the Windows 10 MAIL App to a Yahoo e-mail account. And to avoid Spammers/Junk Mailers there is also a limit on the number of e-mails you can send in 24 Hours. Therefore check what the limits are with your ISP and/or E-Mail Account provider, if different, before attempting to send/receive e-mail in general.

The above is only making you aware of these things. Meaning, these days the above mentioned scenarios/problems should not occur simply because storage and bandwidth do not tend to be a problem for the major ISPs and E-Mail Account providers. However, it does pay to check the Terms & Conditions of your ISP or E-Mail Account provider before signing up to anything.
