Gmail account set up issue in Business Central Online

Hi Gurus,

I have tried Gmail account register as follows in the Business Central online Ver. 25.5 Sandbox environment.

But can't make email sending test with error.

The user name (email address) and password is definitely correct and the Gmail account's "Security">>"Less Secure App Access" option is turned on but not set up the "2 Step Verification" and "App password" because this email account is company managed one.

Please let me know how I can fix this issue.

Thank you,

Danny

Copy that password from gmail and paste it into SMTP setup password in Business central. Hope this will help you.

To successfully set up a Gmail account in Business Central (Online), you must generate an App Password from your Google account. This requires enabling 2-Step Verification. Regular Gmail passwords won't work due to Google's security restrictions. After generating the App Password, use it in the SMTP setup in BC instead of your usual password.

It seems like the issue might be related to Google’s security policies. Even with "Less Secure App Access" enabled, Google often blocks access for third-party apps. You might need to use an "App Password" or check if your company’s admin has enabled API access for the account. Also, ensure that IMAP is enabled in Gmail settings. If the problem persists, consider using OAuth 2.0 authentication instead of basic credentials.
