Office365 SMTP Orchestration

Stop looking at IT to please Microsoft
The Office 365 SMTP setup experience playbook spells out every step - SMTP AUTH, TLS 587, OAuth2 prompts and dedicated App passwords. We turned this checklist into a guided tour with policy enforcement: Dureach is responsible for verifying DNS records, enabling SMTP in the Microsoft 365 admin center, and storing app passwords encrypted, so revenue operations no longer need to ask customers for screenshots.
Every email is under control
Clearly see which Outlook mailboxes are being warmed up, which ones are limited to 30 messages per day, and which authentication links are broken. The system automatically alerts when Microsoft turns off SMTP, login failures spike, or OAuth tokens expire. Delivery charts combine Inbox Placement testing with Office365 telemetry to help determine if fluctuations are coming from infrastructure or copywriting.
Real-time repair
When the username/password is wrong or SMTP is disabled, the fix steps are often buried in the admin backend. Dureach brings these switches to a single interface: you can regenerate app passwords, reconnect via OAuth, or clone a compliant mailbox that inherits the same DKIM/SPF settings. Built-in blacklists and throttling follow outreach email limit guardrails guidelines to control each mailbox within Gmail’s 0.3% complaint rate and Microsoft’s 10,000 recipient limit.
Route
The next step will be to add an AI assistant to mark risk configurations after policy changes, automatically repair OAuth, and write logs to Microsoft Audit Center to facilitate the compliance team to track every SMTP adjustment.
