How to Fix Repeated IMAP Gmail Password Prompts in Outlook
Question details
Microsoft Outlook repeatedly prompts the user to enter their Gmail username and password for the imap.gmail.com server, even though the credentials should be saved.
- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- The user is trying to access or sync their Gmail account using IMAP within Microsoft Outlook.
- Observed behavior
- Outlook continuously displays a pop-up asking for the IMAP server (imap.gmail.com) credentials, either rejecting the entered password or failing to retain it.
Verify that you are using the correct Gmail password by logging into your Gmail account directly via a web browser before troubleshooting Outlook.
Repair Microsoft Office via Apps & Features
Use the built-in Windows repair tool to fix underlying Microsoft Office issues that cause Outlook to forget or reject saved passwords.
By default, when a Gmail account is added to Microsoft Outlook, the password is retained. If the application keeps prompting for credentials, the Outlook client itself might have a corrupted profile or configuration that requires a repair.
Restart your computer completely to ensure no Office background processes are stuck in a frozen state.
Right-click the Windows Start button and select 'Apps and Features' (or 'Installed apps' in newer Windows versions).
Scroll through the list to find your version of Microsoft Office, click on it, and select 'Modify'.
Choose 'Repair' from the prompt and follow the on-screen instructions to begin the troubleshooting process.
Once the repair is complete, open Microsoft Outlook and check if the IMAP password prompt is resolved.

Frequently Asked Questions
Why does Outlook keep asking for my Gmail password even when it's correct?
This typically happens if two-step verification is enabled on your Gmail account (requiring a special App Password), if 'Less secure app access' is disabled in your Google settings, or if your Outlook profile data has become corrupted and fails to retain saved credentials.
Do I need a special password for Gmail in Outlook?
Yes, if you have two-step verification enabled on your Google account, you cannot use your regular Gmail password in older versions of Outlook. You must generate an 'App Password' from your Google Account security settings and enter that 16-character passcode into Outlook instead.
How do I fix the IMAP connection if repairing Office doesn't work?
If an Office repair fails, try removing the Gmail account entirely from Outlook via the Account Settings menu, restarting Outlook, and then adding the account back to force the system to establish a brand-new IMAP configuration.
