Converting Thunderbird 1.5 from POP to IMAP
Step 1 - Open Thunderbird – in the left pane you should see your email account (in this case called pop.mun.ca, but yours may have a different name, such as your email address) and your Local Folders. Expand both headers. If you only have Local folders, you can skip to Step 7.
Step 2 - Go into an email folder for your POP email account, and select all of those email by holding down the Ctrl key and hitting the A key on your keyboard. This is the shortcut key for “Select All.” After this, all of your mail in the folder should be highlighted, as shown below.
Step 3 - Right-click on the highlighted mail and select “Copy To", then “Local Folders”, and the name of the destination folder – if a desirable destination folder does not exist, you can create one by skipping to Step 4.
Step 4 - If you have a folder in your email account that is not under Local Folders, you can add a new folder with the same name, or any name that you wish. Right-Click on the Local Folders heading and select “New Folder…” as shown below.
Step 5 - Name the new folder, and set “Create as a subfolder of:” to Local Folders. Click OK.
Step 6 - You can return to Step 3 above for assistance on copying mail from the POP folders to the Local Folders. In the example below, the “Old Inbox” folder now contains all of the mail that is in the POP Inbox.
Repeat the process as necessary – create as many folders as you like under Local Folders, and move as much mail as you like from your POP account by selecting it, and copying it to Local Folders. This will back up your mail to your local computer.
You should now be ready to remove the POP account and add IMAP.
Step 7 - Click Tools, Account Settings…
Step 8 - Select your account name from the left pane of the window and click Remove Account. Click OK to confirm that you want to remove the account settings.
Step 9 - Click Add Account – this will open the Account Wizard.
Step 10 - Select Email Account and click Next >
Step 11 - In the “Your Name” field enter your name as you would like it to appear in the From field of outgoing messages, and enter your email address; click Next >
Step 12 - For the incoming server type select IMAP, and enter the Incoming Server name as mail.mun.ca, and if necessary enter the Outgoing Server (SMTP) as smtp.mun.ca; click Next >
Please note: if you are using an internet service provider other than MUN, then you will need to ask your Internet Service Provider for the proper Outgoing Server (SMTP) settings for your e-mail.
Step 13 - For Incoming Username: enter the username for your e-mail account; click Next >
Step 14. Enter the Account Name; this is the name that you will use to refer to your account for the sake of identification, and you may choose any name you want; click Next >
Step 15 - Verify that all of the information is correct, and click Finish.
Step 16 - Click OK to exit the Account Settings window.
Step 17 - Enter your password for your e-mail account – check the “Use Password Manager to remember this password.” box if you do not want to be prompted for the password again; click OK.
Step 18 - Your mail will now be listed under the header that is your account name (in the example below it is email@example.com) – your folders should automatically synch with Webmail, i.e., should look exactly like your e-mail and folders in Webmail. If they do not synch, close Thunderbird and open it again.
With IMAP setup, your e-mail and e-mail folders under the account name header should look exactly the same as your e-mail and e-mail folders in Webmail. It is recommended that you delete unnecessary e-mail since there are quota limitations for your e-mail account, or move e-mail from the IMAP account folders to your Local Folders in Thunderbird. These folders are only available on your personal computer, and will not synch with Webmail.
