re :Someone tried to help but I don't seem to be able to reply to that person .

No you do not 'Reply' to that person - the email is auto generated by the Forum to let you know someone has posted a comment - it's a 'no-reply' email. You post a comment in the Support Forum. When you get an email that informs you about a comment in a question you asked - in the email you will see a button which asks if this solved the issue and next to it there is some text which is a link and it says something like - it did not solve the problem - click on it that text and it takes you directly to the original qyestion.

re :It seems that my new computer put Thunderbird on an STMP server and my phone and my old computer are on a POP server . i would like to have them all on the same server so that when read or delete they show read or are deleted on all my computers .

SMTP is just the outgoing server and that is required for any mail account otherwise you could not send emails.

You have an email address and it is stored on a server. At this point I have no idea what server you are talking about. You would have to provide information.

• In Thunderbird (on new computer)
• Help > TRoubleshooting Information
• Under 'Mail and News Accounts' section
• Copy all data and paste it into this forum question.

If you want to store all emails on the server and get access to the same data no matter what device you use - old computer, new computer, phone etc...then you need to use IMAP protocol. Generally, when you create a new mail account, Thunderbird by default tends to auto look for the IMAP server settings first.

When you said "new computer put Thunderbird on an STMP server" - I think you mean you have IMAP set up on new computer, so that's good.

But you also say "my old computer are on a POP server " That basically means, the downloaded emails are stored on the old computer. Pop accounts only get access to server Inbox and download emails from server Inbox to POP account Inbox. There is no synchronisation between folders on server and folders in a POP account. Anything you downloaded is on the old computer - whether those emails had left a copy on the server which you can see via the IMAP account is an entirely different question.

Need to know - did the Pop account leave a load of emails on the server? You can see them if you logon to your webmail account via a browser.

On new computer which has IMAP account, can you see all those emails or are they missing/not on server. ?

Now - talking about OLD computer which has Pop account: You cannot convert a Pop account to an IMAP account. At this point do not delete anything. If all the emails you see in Pop account are still on the server, then there is no problem, but if you have many emails in Pop that are not on server then you need to do the following:

• In 'Local Folders' account create some suitably named folders.
• Get copies of all emails into the 'Local Folders' mail account. Do this in batches.
• Make sure you can see - read emails that are now in Local Folders account.

This means you will still have access to those emails via the Local Folders account.

Now you can remove the Pop account via Account Settings. I do not know what version of Thunderbird you are using on old computer.

• In Account Settings
• Select name of account in left pane and on the right you should see a 'Delete' button.
• click on that 'Delete' button to remove the account.

OR

• if you are still using an older version - click on 'Account Actions' and select 'Remove account'

Exit Thunderbird. wait a few moments and then Start Thunderbird. Create a new mail account for the email address and this time set up as IMAP - which Thunderbird tends to do by default, but you should make sure it is IMAP.

Confirm you did the following on old computer:

1. For Pop account - Did you leave all old mail on server or not?
2. Have you got copies of all Pop account emails into 'Local Folders'?
3. Have you deleted the Pop account ?
4. Have you created a new IMAP mail account for the email address ?
