Storing large amount of emails

I have a large amount of emails stored in a mail server (almost 22G), and the service will expire next month. So I want to use Thunder Bird to keep these emails in my local drive for later access. I am new to this software, and have a few questions. 1. Should I use IMAP or POP3 for my purpose? 2. Because it is a huge volume, I guess it may take several days to download all emails. Then, can I turn off Thunder Bird while it is downloading or pause the download process and resume later? What if the downloading process be interrupted due to internet disconnection, power failure or other reasons? Can the software resume where it leaves and ensure the integrity of all emails? Thank you for any help!

Just my thoughts: - I would do IMAP (although POP could work and both have similar exposure to any interruption) - check that account settings>synchronization&storage is set for offline use - set File>offline>download to ensure all headers and messages are retrieved - once you have all messages downloaded, I would create filters to separate messages into smaller groups, in Local Folders.

   My reasoning is that Thunderbird could choke, trying to manage 22g of mail in one folder (just my opinion)

- once done, check that all messages are accounted for and then delete the IMAP account. - finally, exit thunderbird and do two backups of the profile folder with WIndows File Explorer

AND, I suggest waiting for other suggestions, as there may be other possibilities in this.

Thank you, David. My emails are classified and stored in folders on the mail server. You suggested that I separate messages into smaller groups in local folders. Does Thunder Bird keep the folder structure when it downloads? If yes, then probably I don't need to create the small groups manually.

Hi,

How are you accessing your messages now? Do you have a way of exporting them from your expiring server to mbox files? You might be able to do that without having to do anything with Thunderbird, which would make your task easier.

If you can get them into mbox files on your local drive, everything after that is easy.

Hi, Rick, I access the emails via web browsers. There is no option for me to export emails to local drives. But thank you for this suggestion. I was not aware that there is a such option.

On your structure question, if IMAP, the folders will be reconfigured on PC to match what is on server.

Hi yu_chen,

Before you create accounts in Thunderbird, you probably want to set your message format in Thunderbird to "File per message (maildir)".

I believe that performance and reliability of your large message library will be better.

Thunderbird settings - General - at the bottom

I am not an expert. You may want to do your own research.

I am not sure you want to do this in IMAP, as it may synchronize with the expiring server by deleting all of the mail in your local downloads unless you archive it first! IMAP in Thunderbird is set up as a corporate mail server view port, not as a download alternative to POP, though it can download and keep local copies -- until it deletes them when the server does. I had that happen on Yahoo when it decided that IMAP could only show 10,000 messages at a time, so Thunderbird deleted the ones no longer visible, though Yahoo still had them on its web mail. Exporting those required moving them around on Yahoo to a different folder, synchronizing to it, and copying those messages to a non-sync folder in T'bird. POP is the safe way to get and keep messages, especially when you don't control the server. IMAP is the safe way for an IT department to manage what its lusers see.
