Moving Stony Brook Google Mail Messages to a Personal Gmail Account Using Thunderbird

If you would like to move your email messages from your Stony Brook University Gmail inbox to your personal Gmail inbox, you will need to use an email client like Thunderbird or Apple Mail (for Mac users). By using an email client you can drag and drop emails from one account into another! 

Step 1. Enable IMAP in your Stony Brook Google Mail and Personal Gmail Account

Make sure you must enable IMAP access for your Stony Brook University Google Mail account AND for your personal Gmail account (if you don't already have one, create one at http://mail.google.com). To enable IMAP access, follow these directions:

1. Log into your Stony Brook University Google account (https://my.stonybrook.edu) with your NetID and NetID password or personal Google account with your username and password
2. Click on the gear near the top right corner and then select See all settings
3. Click Forwarding and POP/IMAP
4. Under "IMAP Access" select Enable IMAP and then at the bottom click Save Changes
   
5. Log into your personal Google account (mail.google.com) and repeat steps 2-4

Step 2. Download Thunderbird

http://www.mozilla.org/en-US/thunderbird/ 

1. Click the download button and run the .EXE file. Your OS may prompt you with security warnings. If so, click Run
2. On the Setup screen, click Next and then choose the Standard setup > Next > Install > Finish

Step 3. Set up Thunderbird with your Stony Brook Google Mail account

You will need to set this up twice; once for your Stony Brook account and then again for your personal gmail account.

1. Open Thunderbird
2. In the top right, click the menu icon (three horizontal lines ) and select Account Settings OR Options or Preferences  and then Account Settings
3. At the bottom of the screen, click Account Actions and then Add Mail Account
4. Enter your name, email address, and password, and then click Configure manually
5. Enter this server information:
   Incoming: imap.gmail.com  |   Port: 993  |  Connection security: SSL/TLS  |  OAuth2
   Outgoing: smtp.gmail.com  |  Port: 465  |  SSL: SSL/TLS  |  OAuth2
   Username (incoming and outgoing): first.last@stonybrook.edu
6. Select Advanced config
7. On the left under the first.last@stonybrook.edu email address, click Server Settings. For Authentication method, select OAuth2
8. On the left click Outgoing Server (SMTP), click to select your email address, and then click Edit
9. Change the Authentication method here to OAuth2 then click OK
10. Once your Stony Brook account has been added, in the list of the left click Inbox under your @stonybrook.edu account
    If you don't see Inbox, double-click your first.last@stonybrook.edu email address, and the word Inbox will display below it.
    If you get an error that the mailbox can't connect, double click on your first.last@stonybrook.edu email address to open NetID sign in.
    1. If prompted to sign in with NetID and NetID password, sign in, and then and grant Thunderbird access by clicking Allow (click i to learn about what this means)
    2. If you have trouble authenticating your @stonybrook.edu account, update Thunderbird

Step 4 Set up Thunderbird with your Personal Gmail account

1. Add your personal Gmail account by following the instructions from Step 3:
   1. In the top right, click the menu icon (three horizontal lines ) and select Account Settings OR Options or Preferences  and then Account Settings
   2. At the bottom of the screen, click Account Actions and then Add Mail Account
   3. Enter your name, email address, and password, and then click Configure manually
   4. Enter this server information:
      Incoming: imap.gmail.com  |   Port: 993  |  Connection security: SSL/TLS  |  OAuth2  |  Username: your email address
      Outgoing: smtp.gmail.com  |  Port: 465  |  SSL: SSL/TLS  |  OAuth2  |  Username: your email address 
      Click Done

Step 5 Drag Emails/Folders between Accounts

1. Once you have added both accounts to Thunderbird, drag and drop emails/folders from one inbox to the other
   note: you must have enough space in your personal Gmail account to accomomdate the emails you move over
