AutoReply365

Automate replies in Microsoft 365 shared mailboxes with a centralized, deterministic rule engine.
AutoReply365 gives organizations clear, predictable control over automated replies in Microsoft 365 shared mailboxes. Instead of scattered transport rules, hidden Power Automate flows, and inconsistent behavior across support@, sales@, or jobs@, AutoReply365 centralizes everything into one governed system your IT team can trust.
Built for clarity, not complexity
Shared mailbox automation often grows messy: overlapping rules, unclear ownership, accidental overrides, or missed replies. AutoReply365 replaces this with a deterministic, rule-based engine that behaves exactly as configured — no AI, no unpredictable logic, no hidden automation layers.
This is intentional. Many teams need automation that is reliable, audited, and fully under administrative control. AutoReply365 delivers that with precision.
Consistent, controlled automation
Create rules that define exactly when and how replies are sent:
- Send different replies inside and outside business hours
- Match specific subjects, keywords, or sender types
- Apply different logic for internal vs. external senders
- Forward messages to additional mailboxes or addresses when needed
All processing is handled by a loop-safe engine that analyzes message headers, conversation IDs, and sender cooldowns—ensuring your tenant stays protected from auto-reply storms and unwanted behavior.
Professional communication at scale
Craft clean, branded templates using dynamic Liquid-style variables. Liquid is a well-known templating language used by platforms like Shopify and GitHub, allowing you to insert contextual data such as or directly into your replies. Every message remains consistent, personal, and fully under your control.
Secure by design, aligned with Microsoft 365
AutoReply365 connects through Microsoft Graph API application permissions, with no passwords, forwarding tricks, or client-side code. Every auto-reply is sent directly from your own Exchange Online tenant, preserving:
- Audit trails and compliance logging
- Message threading and metadata
- E-discovery visibility
- Delivery reliability and trust
This approach ensures automation remains fully within your organization’s governance model—no external relay service, no mailbox impersonation risks.
Who benefits the most
- IT Administrators requiring centralized control and predictable behavior
- Support and Sales teams who need consistent, timely acknowledgements
- Operations and HR automating confirmations without workflow overhead
- Microsoft 365 consultants delivering maintainable solutions to clients
AutoReply365 is not an AI system. It is a stable, transparent, rule-based platform designed for organizations that value control, consistency, and governance—while still giving teams the relief of dependable automation.
Deploy in minutes. No scripting. No Power Automate complexity. Just clear, governed behavior your organization can rely on.
