# Connect Microsoft OneDrive to Microsoft Outlook > Stop manually saving attachments and sharing files. Let tray.ai keep your OneDrive and Outlook in sync. **Canonical page:** https://tray.ai/connectors/microsoft-onedrive-microsoft-outlook-integrations/ **Microsoft OneDrive connector:** https://tray.ai/connectors/microsoft-onedrive-integrations/ **Microsoft OneDrive documentation:** https://tray.ai/documentation/connectors/service/microsoft-onedrive **Microsoft Outlook connector:** https://tray.ai/connectors/microsoft-outlook-integrations/ **Microsoft Outlook documentation:** https://tray.ai/documentation/connectors/service/microsoft-outlook ## Overview Microsoft OneDrive and Microsoft Outlook are two of the most widely used tools in the modern workplace, yet most teams still manage the connection between them by hand. When emails arrive with important attachments, or files in OneDrive need to go out to stakeholders, the back-and-forth between these two apps eats up time and creates version control headaches. Integrating OneDrive and Outlook through tray.ai automates the flow of files, notifications, and data between both platforms so nothing falls through the cracks. Integrating Microsoft OneDrive with Microsoft Outlook cuts out one of the most common sources of workplace inefficiency: manually moving files and documents between your inbox and cloud storage. Teams that rely on both tools burn real time downloading email attachments, uploading them to the right OneDrive folders, sending one-off sharing links, and pinging colleagues when new documents are ready. Automating these handoffs with tray.ai gives you a reliable, auditable pipeline where every important attachment lands in the right folder, every stakeholder gets a timely notification, and every shared link reaches the right inbox. The result is faster collaboration, less risk of lost or misplaced files, and a consistent process that actually scales. ## Use cases ### Auto-Save Email Attachments to OneDrive When an email arrives in Outlook matching specific criteria — a sender domain, subject keyword, or destination folder — tray.ai automatically extracts all attachments and saves them to a designated OneDrive folder. No more downloading and organizing files from your inbox every day. - Every attachment gets archived in OneDrive without anyone touching it manually - Important files don't get lost or buried in a cluttered inbox - Attachments are sorted into structured folders based on sender, date, or subject rules ### Send Outlook Notifications When New Files Are Uploaded to OneDrive Whenever a new file or folder appears in a specific OneDrive location, tray.ai can automatically send a personalized Outlook email notifying the right team members or external stakeholders. Everyone stays informed without manual follow-up. - No more manually telling teams when a document is ready for review - Fewer delays in document-driven workflows like approvals and sign-offs - Notification content includes file metadata like name, uploader, and a direct link ### Convert Outlook Emails into OneDrive Documents for Record-Keeping Important email threads, contracts, or summaries in Outlook can be automatically converted to documents and saved to a designated OneDrive archive folder. This is especially useful in compliance-heavy industries where email content has to live alongside other business records. - Builds a structured document archive from email content without manual copying - Supports compliance and audit requirements by storing email records in OneDrive - Eliminates copy-paste workflows for documenting email exchanges ### Share OneDrive Files Automatically via Outlook When a Trigger Occurs When a document hits a certain stage in a workflow — a contract finalized, a report published — tray.ai can generate a OneDrive sharing link and send it to designated recipients via a templated Outlook email. Stakeholders always get the latest version without delays. - No manual step of generating and distributing file sharing links - The right version of a document always goes to the right audience - Speeds up distribution across approval, reporting, and delivery workflows ### Organize Incoming Invoice Attachments from Outlook into OneDrive Finance teams often get dozens of invoices via Outlook every day. With tray.ai, attachments from emails identified as invoices are automatically routed into structured OneDrive folders organized by vendor, date range, or invoice number — ready for processing or review. - Dramatically cuts manual effort for finance teams dealing with high attachment volumes - Creates a clean, searchable invoice archive in OneDrive for accounting purposes - Works naturally with downstream approval or ERP workflows ### Alert Teams in Outlook When OneDrive Files Are Modified or Deleted tray.ai can watch specific OneDrive folders for file changes, deletions, or permission updates and automatically fire Outlook alerts to designated owners or team leads. You get visibility into document lifecycle events without anyone having to constantly check OneDrive. - Real-time alerts when something changes in sensitive or business-critical OneDrive folders - Unauthorized edits or accidental deletions don't go unnoticed - Distributed teams stay current on document status without manual check-ins ### Sync Email Campaign Assets from Outlook to OneDrive for Marketing Teams Marketing teams regularly receive creative assets, brand files, or campaign briefs via Outlook from agencies and partners. tray.ai can automatically detect these emails, pull the attachments, and store them in structured OneDrive campaign folders — so creative libraries stay organized without anyone managing them by hand. - OneDrive campaign asset libraries stay current without manual file management - No more working from outdated assets buried in email threads - Marketing coordinators spend less time on repetitive file-handling tasks ## Templates ### Save Outlook Email Attachments to OneDrive Automatically This template monitors a specified Outlook inbox or folder for incoming emails with attachments and automatically uploads those files to a pre-configured OneDrive folder, preserving the original file name and metadata.

Simple integrations tend to fail silently or time out, leaving files unsaved with no one the wiser. **How Tray.ai helps:** tray.ai handles large file transfers through resilient, multi-step workflows that can chunk or stream file content where needed. Built-in error handling and retry logic mean failed uploads are retried automatically, and teams get alerted if a file can't be saved — no silent data loss. ### Mapping the Right Files to the Right OneDrive Folders Dynamically Organizations rarely store everything in one place. Invoices go to finance folders, contracts go to legal, project deliverables go to team directories. An integration that dumps everything into a single folder becomes unusable fast. **How Tray.ai helps:** tray.ai's branching and conditional logic let teams build folder routing rules based on email metadata like sender address, subject keywords, or custom headers. Folder paths in OneDrive are constructed dynamically at runtime, so every file lands exactly where it belongs. ### Avoiding Duplicate Files When Emails Are Forwarded or Re-sent In busy email environments, the same attachment can show up multiple times through forwards, reply-alls, or automated re-sends. Without deduplication logic, your OneDrive fills up with duplicate files and downstream users end up confused about which version is current. **How Tray.ai helps:** tray.ai workflows can run deduplication checks by comparing file names, sizes, or hashes against existing OneDrive contents before uploading. Conditional logic ensures already-existing files are skipped or versioned rather than duplicated, keeping your document store clean. ### Maintaining Secure Sharing Without Overexposing OneDrive Files Auto-generating OneDrive sharing links via Outlook introduces real risk if those links are set to the wrong permission level — say, an organization-wide link when only one external partner should have access. That kind of misconfiguration can expose data you didn't mean to share. **How Tray.ai helps:** tray.ai lets teams define sharing link parameters programmatically when calling the OneDrive API, including link scope (specific people, organization, or anonymous), permission level (view or edit), and expiration dates. Every link generated and sent via Outlook follows your organization's data sharing policies. ### Keeping Workflows Running as Microsoft API Tokens Expire Microsoft's OAuth token refresh lifecycle for OneDrive and Outlook can quietly break integrations when tokens expire — leading to missed file saves or unsent notifications that nobody catches until a user reports something is wrong. **How Tray.ai helps:** tray.ai manages OAuth authentication and token refresh automatically for both Microsoft OneDrive and Outlook connectors. Credentials are stored securely and refreshed in the background, so workflows keep running and teams never have to manually re-authenticate their connections. ## Learn more - Intelligent Integration: https://tray.ai/platform/intelligent-ipaas/ - Merlin Agent Builder: https://tray.ai/platform/merlin-agent-builder/ - Agent Gateway for MCP: https://tray.ai/platform/agent-gateway/ - Book a demo: https://tray.ai/contact/
