Nothing stalls a workday faster than email problems. Whether it’s an “authentication failed” message, a full mailbox, or a stubborn error code, these issues can feel overwhelming — especially when you rely on email to reach customers. At MaineBizPros, we see these problems all the time, and the good news is: most are simple to fix.
1. “Authentication Failed” or “Invalid Password”
Cause: Wrong password, or the email program is trying to connect without the right security settings.
Fix:
-
Double-check your password (try logging in through webmail to confirm).
-
In your email program, make sure SSL/TLS is turned on.
-
Confirm your incoming/outgoing server names match the settings provided.
2. “Mailbox Full”
Cause: Your mailbox has hit its storage limit.
Fix:
-
Delete old or large emails (especially attachments).
-
Empty your “Sent” and “Trash” folders.
-
If you need more space, contact us to expand your mailbox quota or help you archive older mail.
3. Emails Won’t Send (Stuck in Outbox)
Cause: Outgoing server (SMTP) not set correctly, or authentication missing.
Fix:
-
In account settings, check “Outgoing server requires authentication.”
-
Confirm port number is 465 or 587 with SSL enabled.
-
Restart your email app and try again.
4. Emails Not Syncing Across Devices
Cause: Account is set up with POP instead of IMAP.
Fix:
-
Switch to IMAP so changes (read, delete, move) stay in sync across all devices.
-
If unsure, we can help migrate your old POP account safely to IMAP.
5. Receiving Mail but Can’t Send (or Vice Versa)
Cause: Partial server settings entered, or ISP blocking certain ports.
Fix:
-
Re-check both incoming and outgoing settings.
-
If sending fails only on Wi-Fi, try switching networks or call us to check port restrictions.
