So, let’s find out how you can fix the Google 78754 (Failure) on Outlook error.
What is error 78754 failure in Outlook?
The 78754 (Failure) in Outlook is a login error that appears when users try to access their Gmail (Google Mail) account via Microsoft’s email client.

Suspicious login detected: When you try to log in from a new device or another location, or the activity seems unfamiliar, Outlook may throw the error. Incorrect password: The error also appears when the password entered for the Gmail account is incorrect. Additional security measures: There may be an additional password required to sign in, or 2-FA set up on Gmail. Misconfigured IMAP settings: Having IMAP disabled altogether or even a slight misconfiguration in settings could trigger the error.

Ensure the login credentials, both the email address and password, entered for the Gmail account are correct. If you haven’t updated Outlook in a while, check for any new versions and install them.
