Maybe, try setting-up a second Gmail account, then send transfer) your emails from the old username account to the new username account. If this works, then either try deleting the messages from the old gmail account and transfer the messages from the new gmail account back to the original gmail account ... or ... just delete the old gmail account if you successfully transferred them to the new gmail account.

How are you accessing your account? Have you tried using a browser?

It is not uncommon for a person to have more than one email account.
Most email service providers offer their customers a way to import email contacts and messages from other email accounts into the account maintained by the provider.

Some email service providers, such as Gmail and Yahoo Mail, have an email migration tool built in to their email interface.

Other providers, such as Comcast, direct their customers to use the TrueSwitch email migration tool.

From what provider are you trying to configure email?If its gmail,

1. Create a Lotus Notes database file to store your POP emails: Lotus Notes does not create a file automatically as Thunderbird or other mail clients do but you have to manually point the mails to flow to a file that is already existing.
2. In the local Address Book, create two accounts for accepting incoming email and sending outgoing email on Gmail. Names are not important but the configuration on the two accounts is!
Account document for Incoming Gmail:
The Basics tab
a. Account name: Can be anything (I chose In Gmail)
b. Account server: pop.gmail.com
c. Login Name: Your gmail email address (complete with the @gmail.com)
d. Password: Your password
e. Protocol: POP
f. SSL: Enabled
g. Only from Location(s): Doesn't matter. Although I would recommend creating a location document specific for Gmail if you are also using Domino Server. I chose creating a location (Gmail).
Protocol Configuration tab: There is only one field here and it doesn't matter what you do with it.
Advanced Tab: This is the most important tab.
a. Port Number: 995
b. Accept SSL site certificates: Yes (Most of the articles on the web tell you to choose No here. But it does work. Trust me. I have tried it)
c. Accept expired SSL certificates: Yes. (Most of the articles on the web tell you to choose No here. But it does work. Trust me. I have tried it)
d. Send SSL certificates when asked (outbound connections only): No.
e. Verify account server name with remote server's certificate: Disabled
f. SSL protocol version: V3.0 with V2.0 handshake
3. Click on Save and Close to save the document and exit. Now you will need to create another account document to handle the outgoing email.
Account document for Outgoing Gmail:
The Basics Tab
a. Account Name: Can be anything. I chose Out Gmail
b. Account server name: smtp.gmail.com
c. Login Name: Your gmail email address (complete with the @gmail.com)
d. Password: Your password
e. Protocol: SMTP
f. SSL: Enabled
g. Only from Location(s): Doesn't matter. Although I would recommend creating a location document specific for Gmail if you are also using Domino Server. I chose creating a location (Gmail).
Advanced Tab: This is the most important tab.
a. Port Number: 587 or 465 (Both are SSL port and both work)
b. Accept SSL site certificates: Yes (Most of the articles on the web tell you to choose No here. But it does work. Trust me. I have tried it)
c. Accept expired SSL certificates: Yes. (Most of the articles on the web tell you to choose No here. But it does work. Trust me. I have tried it)
d. Send SSL certificates when asked (outbound connections only): No.
e. Verify account server name with remote server's certificate: Disabled
f. SSL protocol version: V3.0 with V2.0 handshake
4. Once these two documents are created, I would recommend creating a location document to ensure that you separate your gmail from your other Domino based account on the client. The steps to create are:
5. In the same local Address Book, choose New --> Location
Basics Tab:
a. Location Type: Local Area Network
b. Location Name: Can be anything (I chose Gmail)
c. Internet Mail Address: Your gmail email address
Leave the rest as it is.
Servers Tab:
a. Home/Mail server: pop.gmail.com
Leave the rest as it is.
Ports tab: No changes (ensure TCPIP is checked)
Mail Tab (Most important):
a. Mail file location: Local
b. Mail file: My Gmail.nsf (whatever you created in step 1 above).
Update: A couple of readers pointed out that I had missed an important step in the configuration how-to. So here it is. Step C has been added to include the missed step.
c. Internet domain for Notes addresses when connecting directly to the Internet: gmail.com
d. Send Outgoing mail: directly to Internet
Leave the rest of the fields as it is.
6. There is no need to change the rest of tabs. Click on Save and Close to create the document.
Change to the the new location and you will see Gmail getting downloaded in the mail file you created.
