When setting up email accounts, you may encounter technical limitations from email providers or authorization errors. Below are the most common problems and their quick solutions.
Outlook / Microsoft 365 Email fails to connect
To connect Outlook and Microsoft 365 to third-party services, OAuth 2.0 authorization is required, as Microsoft has disabled Basic Authentication - using a standard username and password for the SMTP protocol. Unfortunately, connecting these email services to Grinfi is currently unavailable.
Authorization Error When Connecting Gmail
If you are connecting a Google email account and receive an authorization error, it is most often due to an incorrect password. Common mistakes include:
Using the primary password instead of an App Password: For security reasons, Google blocks login attempts via third-party services using your regular email password. To connect, you must use an App Password.
The Difference: You create your primary password yourself. However, an App Password is a unique code consisting of 16 random letters generated automatically by Google.
You can find a step-by-step guide on generating an App Password during the first stage of the Gmail connection process within the Grinfi interface.
Password validity: If you previously created an App Password but recently changed your primary Google account password, your app passwords may have been deactivated by Google's security system. You will need to generate a new App Password.
Temporary glitches: If the password is correct but the error persists, wait 30-60 minutes and try again. We may be deploying a platform update or performing routine maintenance at that time.
Connection Errors for Other Providers (Custom SMTP)
If you are connecting email from a custom provider and encounter an authorization error:
Change the connection port: The most frequent cause is using SMTP port 465. Try changing the port value to 587, even if your provider's official instructions specify 465. In most cases, this resolves connection blocking issues.
Check syntax: Carefully review your authorization details (email address, password, host addresses). Make sure there are no accidental spaces at the beginning or end of the fields.
Test the connection: Try connecting this email to any other email client via SMTP to ensure there are no hidden restrictions on your provider's side.
Error on an Already Connected Email
If a previously connected email suddenly stops working or displays an error, you need to reconnect it to the platform.
Go to the list of your connected email accounts.
Click the three dots icon (...) next to the specific mailbox.
Select Reconnect from the dropdown menu.
Complete the connection process again to refresh the session.
