Using classic Outlook for Windows in business environments
Dear Cheryl Lieberman
Welcome to Microsoft Community.
Here you see that you failed to add Gmail mailbox in Outlook.
I would like to ask you a few questions about your issue.
What version of Outlook are you using? (365/Office Outlook, Outlook.com, Outlook New)
Did you try to enter your Gmail address and did it work?
Is the password in your screenshot your Gmail password?
Do you use IMAP or POP to join your mailbox?
For your question, since the information here is incomplete, you can try to follow the basic procedure below to troubleshoot the error:
- Check your Gmail account settings: Make sure IMAP access is enabled in your Gmail account. You can find this option in the Settings Center in Gmail.
- Check your firewall and antivirus software: Sometimes your firewall or antivirus software may block Outlook from communicating with your Gmail server. Make sure your firewall and antivirus software allow Outlook to communicate.
- Try a manual setup: You can try setting up your Gmail account manually. In Outlook, select File > Add Account, and then select Manual Setup or Other Server Type. Choose Next, and then select Internet Email. Enter your account information, including the server name (imap.gmail.com) and connection type (select IMAP).
- Try auto-configuration: From within Outlook, you can select Add Account and click on the Google category to add it without changing any ports.
- Check App Password: If your Gmail mailbox is added to Outlook, you need to enable the “less security app access” function in Gmail when configuring Outlook, and you need to enter your Gmail app password in the Password column in your screenshot. You can also enter the Gmail app password in the password column of your screenshot. You can generate an app password in Google account security settings and try again.
If the above options do not resolve the issue, please let me know if I am unable to send the message and I will continue to process it for you once I receive it.
Feel free to text back if you need further help.
