I wish to copy all my emails from an email account on EveryOne.net webmail to a client platform for full offline access..

Meaning, I want to pull a copy of every email (all attachmens included) on their email server onto my PC, which i can then read or search through offline..

Most email clients refuse to pull pre-existing email from the servers, and/or quit halfway, or leave attachments behind, etc.

I guess this could be called an offline 'copy' or 'mirror' or 'backup', but so far I've not found a way to do this properly, and have come to you experts seeking your advice..

I want to address this first.

The only advise I can offer at this point is that an IMAP connection from Pegasus Mail to your EveryOne.net mailbox 'might' work to allow you to access all messages. Those accessed should then be able to be copied to local Pegasus Mail folders. I say "might" because IMAP access to specific folders may need to be allowed on EveryOne.net and then Pegasus Mail will need to be configured to access specific folders on EveryOne.net

First not an IMAP users so don't know about this stuff.

Google.com AI question returned this. Assume Pegasus would be able to do same as thunderbird??

To back up all emails from an Everyone.net account, the most reliable and secure method is to connect your account to a desktop email client using IMAP protocols and download the data locally.

Configure Server Settings: If Thunderbird does not automatically find the settings, choose Manual Setup and input the following Everyone.net IMAP settings:
    Incoming Mail Server (IMAP): imap.everyone.net
    Port: 993 (Requires SSL/TLS)
    Outgoing Mail Server (SMTP): smtp.everyone.net
    Port: 465 or 587 (Requires SSL/TLS or STARTTLS)

Export the Data: To ensure you have a permanent backup file, you can install the "ImportExportTools NG" add-on inside Thunderbird. Right-click your account folder, choose ImportExportTools NG, and select Export all folders with structure to save them as .mbox or .eml files on your hard drive.

Method 2: Using Professional Mail Backup Tools
If you have a massive mailbox or need your emails explicitly converted into an Outlook-friendly format (like .pst), you can use third-party webmail migration software.

Select IMAP Server or Webmail as your source option within the software.
Enter your Everyone.net login credentials along with imap.everyone.net as the host server.
Choose your preferred output format (such as PST, MBOX, PDF, or EML).
Set a local destination path on your computer and click Backup.

There appears to be an error by AI when it states "It will download all your subfolders". The IMAP protocol does not download anything. It is just a mechanism that allows you to interact with what is on the server. Downloading requires the intentional act of storing copies somewhere else. How this is done depends on the intention for usage of the copies.

Note: The original post used the word "move". I use "copy" because you want to insure you have a successful copy before deletion of the original. A failed "move" could result in the source being deleted without a successful write to the destination, hence the my recommended workflow of: copy > verify destination > delete source.

Hmm.. I cannot figure out how to quote reply to each response posted here, so I'll do a bulk comments here..

Yes, "copy" is more correct t than "move", ty, go with that term..

Yes, if all or any email clients is too broad then just consider pmail's email client and proffer your response(s)..

Yes, EveryOne.net allows a modern implementation of both POP3 and IMAP..

"AIs" are not my go to if humans still exist somewhere on Earth's networks, but that would still have me looking for a subset of those online humans that knew something of the topic in the OP..

If i fail to find such human responses, i too, may be forced to consider what an "AI" has stolen from people's private or public online dialogs without explicit consent, and/or people's published documents that are usually copyrighted, and then blindly regurgitated (albeit full of errors)..

I have considered Thunderbird.., I would consider an email tool if a human has some experiences to share about using a particular tool or toolbox or type of such..

Mostly I do not think IMAP is the correct protocol bc of what is clearly inherent in that protocol's design, which seems to be to more or less 'reflect' the new or possibly current Inbox, there would have to be additional step(s) to actually fully copy all the past emails including attachments to the client location for offline storage..

To answer about my client platform, it would be either a WinPro10/11 PC or an Android phone..

Apologies for the possible tl;dr reactions of those disinclined to parse my coagulated replies here.. =)

The problem with POP3 is that it only retrieves mail that is in the inbox, and mail that is "unread". It will not download mail that has been placed in other folders on the host server. As for "unread", I don't know whether EveryOne.net flags messages that have been read as such in regards to POP3. OTOH, IMAP should be able to access mail in all folders on the host. As previously said, some effort may be required on the server side to grant IMAP access to folders, and on the Pegasus Mail side subscribing to those folders.

You are correct that an extra step will be required to download messages. Keep in mind that the download process stores the messages locally in a format that is only easily accessible by the email client that downloaded them.

Pegasus Mail will not run on an Android device. Thunderbird has an Android version. Regarding Thunderbird vs Pegasus Mail, I have not looked at Thunderbird in many years so can't provide a detailed comparison but feel confident in saying that Thunderbird will likely feel more modern compared to Pegasus Mail. Thunderbird is a Mozilla product. Pegasus Mail is the product of, and maintained by, a single individual.

TY for pointing out how to quote reply! =)

I suppose since I've asked, that everyone would've already answered what the mysterious "extra steps" are, but just to be sure, what are the extra steps needed exactly, or if that's too restrictive then in less exact steps, either for any particular email client or pmail's email client..?

Yes, EveryOne.net's email behaves much like most email servers do these days, so one may assume so as they postulate advice to the OP..

It really depends on the ultimate vision for how the downloaded messages will be accessed. I simple form, the email client accesses the messages on the host server using the IMAP protocol then those messages are copied to local folders in the email client. Access the requires use of the email client to look at the messages in those folders. To be clear, a Pegasus Mail "folder" is very different from a Windows folder in that it is made up two files that contain the data and an index. You can not browse it with a file explorer so keep that in mind. I don't know how Thunderbird folders work.

If you do not have any experience with an email client then these concepts may feel completely foreign and won't make sense until you actually start playing with one. You can safely "play" because IMAP does not touch the source files unless you intentionally initiate an action, like a delete. You can safely play with copying to local folders to get a feel for how that works.

Anecdote: About a year ago my ISP announced that they were discontinuing email service. My wife had an email account that she accessed solely via their webmail interface so once she had everything switched over to a Gmail account, I installed Pegasus Mail on her laptop and used its IMAP to access and copy all message into local Pegasus Mail folders. This serves as an archive of all email prior to switching to Gmail.

What you did for your wife is exactly what I need to do for myself, so I'm here asking.. Would you be so kind as to elaborate further, as I'm having a problem with the email clients I've tried not fully grabbing all the old emails and/or the attachments of the emails..

I've come to pmail to see if their email client can accomplish my needs, and it sounds like from your experience it can, i have no qualms with the emails not being in some sort of text files as that would not really be normal with attached multimedia in emails..

I am a bit familiar with outlook using a mbox file format, so if pmail also uses one that's fine too, I would only wonder if pmail's mbox format was able to losslessly convert to some other should the need arise in the future, I just need the EveryOne.net emails for archival purposes after all, tyvm..

First know that Pegasus Mail does not natively use MBOX format. It can do exports in MBOX format (.mbx files) though. Thunderbird natively uses MBOX.

I don't know how to help you further. If you want to test Pegasus Mail then you need to install it, configure an IMAP connection to EveryOne.net, make the connection, then copy some messages to local folders. None of this will make any sense until you get into the program. Once in it, we can help you with each step. That said, I think you might be better off using Thunderbird only because I suspect that it will be more user friendly. I have been away from it too long to know that for sure so I think you are at the point where you need to try one and if you don't like it, try the other.

I can't explain why a message retrieved with an email client would not include its attachments unless an antivirus product was removing them. Some can be a challenge to get to work with an email client. Avast is one that I had to uninstall some years ago. Hopefully it is better now, but any AV product that is scanning inbound email may require special attention.

I can see that you want to help, sorry I said "mbox", I just made that word up thinking anyone would know what i meant as idk the terminology too much, lol..

So, just forget i mentioned any other client as well, please don't get all hung up on this or that..

I clearly fit exactly into the same situation as you described about your wife's email situation, so please describe the steps you performed to do that for her, if something needs more details I'll just ask.. =)

First decide if you think you would prefer Thunderbird or Pegasus Mail. Pegasus Mail is very much a legacy program so those who grew up with Windows since Windows 3x are comfortable with it but if you are a modern "app" person then Thunderbird may be better. You would have to find Thunderbird support though, which I suspect is plentiful.

I you go with Pegasus Mail, install it, configure IMAP per the requirements of EveryOne.net (which you might want to verify against what @msetzerii posted), then make a connection. Pegasus Mail has an extensive help file with help link as almost every configuration screen. It also comes with a manual as a PDF document located in its \Programs directory, filename "manual.pdf". It contains much of the same information as the Help however tends to lag behind development documented in the Help file. Still, it remains a valuable resource that can help better explain a topic the remains unclear after reading it Help info.

IMPORTANT: Pegasus Mail must not be installed in either the Windows "Program Files" or "Program Files (x86)" directories. Windows 11 treats those directories as "protected" which means files in them can not be modified. This "protection" prevents Pegasus Mail from functioning properly. Its default installation is C:\Pmail which I suggest sticking with for ease of future support.

If you post for specific help in the future, please start a new thread with an appropriate topic.

Are you saying that all you did was install pmail client and set it to the IMAP settings of the specific email server and it copied all the emails over, new & old, every email on the server, no special or specific setting or anything..?

Just to be sure, bc I've had this fail several times.. like I mentioned, I would either not get all the folders, or all the old emails in the folders, or all the attachments of all the emails..

I'm asking bc it's not been that easy, and would of be happy if it is really so easy..

No, it won't do anything other than display a folder tree showing whatever is located on the remote IMAP server. You'll have to copy those messages from each folder to a local Pegasus Mail message folder you previously created for storing these messages locally. Here's a folder tree on an IMAP server I'm connecting to regularly for checking the INBOX contents:

As Michael said, the IMAP connection just displays what is on the server. Getting messages copied locally is a separate manual step. You 'may' need use EveryOne.net configuration to grant IMAP access to its folders so that Pegasus Mail can access them, and then you 'may' need to subscribe to EveryOne.net folders from within Pegasus Mail for it to access them. I say 'may' because I don't know anything about EveryOne.net. It could go as smooth as a pat of butter sliding on a warm griddle. I'm just trying to make you aware of some configuration hurdles that you 'may' need to figure out.

The protocols (IMAP and POP3) used by email clients to access hosted mail are standardized so they all work pretty much the same way which is why I have mentioned your AV product as a potential cause of your previous failures, especially if it has an email protection component.
