Solution 1: Re-enable Basic AuthenticationĪ quick way to solve this, is to re-enable Basic Authentication for Outlook in your Google Account Settings. This is because Google has turned off Basic Authentication by default for all new accounts and accounts which haven’t synced within the last 30 days and only lets you authenticate via the OAuth 2.0 standard.Īs a result, you’ll get Send/Receive errors (0x800CCC0E) and could get prompted for your Gmail password again in Outlook and the login could fail even when you supply the correct password. When configuring your Gmail account in Outlook (or other mail clients such as Thunderbird and Mail apps on (older) smartphones), you may run into continuous password prompts or sync errors.
