Migrate Outlook IMAP accounts to new email server

close Outlook

Right-click on Start and then click Run

type control and then click OK, to open Control Panel

In control panel, search mail, then click on Mail (Microsoft Outlook xxxx)

Click Email Accounts

Make sure your account is IMAP type

If you have multiple email accounts, some POP3 and some IMAP, make sure we do this operation on IMAP accounts only.

Please read this for Migrate Outlook POP3 accounts

For IMAP accounts, we must backup existing emails before changing account settings

Open Outlook, click File > Open & Export

Choose “Export to a file” and then click Next

Choose “Outlook Data File (.pst)” and then click Next

Choose the IMAP account and then click Next

In Save exported file as, click Browse, and give a name to your backup file (I name mime as derek-backup.pst)

If you have multiple IMAP accounts, it is important to rename the backup file, so that later export will not overwrite previous ones.

Click Finish to start the export

Do not input any password, just click OK.

After export is finished, we begin to change the server settings.

Close Outlook

Go back to the previous Control Panel > Mail settings

change both Incoming and Outgoing server to h12.hksx.com

and then click More Settings

make sure Outgoing Server is set to > Use the same settings as my incoming mail server (this is same as before)

On the Advanced Page

set Incoming server (IMAP) port to 993 and SSL/TLS

set Outgoing server (SMTP) port to 465 and SSL/TLS

If your computer / outlook is older than 10 years, or you are using different product, you may need to try different port.

Incoming Port 993 SSL, or Port 143 None SSL

Outgoing Port 465 SSL, or Port 587 STARTTLS, or Port 25 None-SSL

Click OK and Next

Outlook will test connection, normally you will see this:

If cannot pass this test, you can

1. make sure your password is correct (try login WebMail)

2. try different connect ports/SSL combinations (see above)

Click Close and Finsih

Open Outlook again

After Send/Receive once, you will see all your previous emails disppeared. but don't worry.

We have to import the previous backup now.

Click File > Open & Export > Import/Export

choose “Import from another program or file” > Next

choose Outlook Data File > Next

Browse to the previous backup file > Next

Choose Import to the same folder > Finish

Wait until import finished

All your previous emails come back.

If you have other computers, laptop, hand phone using the same IMAP account

you only need to delete the previous account, and then add a new account with new server settings.

all your emails will come back.
