GrothHub365 Email Sync Fix

My GrothHub365 inbox and the LeadConnector email system keep drifting out of sync: messages appear in one place but not the other, and folders take ages to update. I need someone to jump in, pinpoint the root cause, and leave me with a rock-solid configuration.

What I expect you to do
• Audit the current GrothHub365 settings, DNS records (MX, SPF, DKIM, DMARC), and any IMAP/SMTP or API connections feeding LeadConnector.
• Resolve the synchronisation issue so mail flows instantly both ways—no missing messages, no duplicates, no lag.
• Test end-to-end: send, receive, and folder refresh from GrothHub365, LeadConnector, and at least one mobile client.
• Document exactly what you changed so I can maintain the setup.

When everything is finished I’ll know it’s right because new mail shows up everywhere within seconds and the test messages you’ll send with me land perfectly.
