Salesforce + Microsoft Exchange Online Integration — Outlook CRM Workflow Automation
Salesforce + Microsoft Exchange Online Integration connects Salesforce with Exchange Online — Outlook Mail and Calendar — so sales teams can log customer communications, sync activities, and trigger sales workflows from their mailbox. Timing matters in 2026: Salesforce Lightning Sync stops working when Microsoft retires Exchange Web Services (EWS) in October 2026, and the older Salesforce for Outlook client is deprecated with retirement scheduled for December 2027. IT Partner implements the currently supported path — Microsoft Graph-based integration, Salesforce's Outlook integration with Einstein Activity Capture where appropriate, and Power Automate or Azure Logic Apps automation — and migrates organizations off the retiring sync tools.
What this engagement is
This service integrates Microsoft Exchange Online with Salesforce to reduce manual handoffs between email, calendar, and CRM activity tracking: email, meeting, task, and calendar activity logging to Salesforce records; email-triggered workflows; automated reminders based on Salesforce data; and custom approval or notification workflows through Power Automate or Azure Logic Apps, built on the Microsoft Graph API and the Salesforce REST API. A 2026 deadline shapes many of these projects: Microsoft is retiring Exchange Web Services (EWS) for Exchange Online in October 2026, which ends Salesforce Lightning Sync — any org still using Lightning Sync for contact or calendar synchronization loses it then. Salesforce for Outlook, the legacy add-in, is deprecated with retirement scheduled for December 2027. The Salesforce-recommended replacement is the Outlook integration add-in with Einstein Activity Capture, and Microsoft Graph is the supported API surface for custom mail and calendar automation. IT Partner assesses what you run today, migrates retiring components to the supported stack, and builds the custom logging and workflow automation the standard tools do not cover.
Success criteria
What you receive
How the work unfolds
Confirm business use cases, user groups, Salesforce objects, Outlook behaviors, trigger conditions, reminder rules, and approval or notification requirements. Identify any Lightning Sync or Salesforce for Outlook usage that must be replaced before the EWS retirement in October 2026 or the Salesforce for Outlook retirement in December 2027. Review current Microsoft 365, Exchange Online, Salesforce, Power Automate, and security configuration before finalizing scope.
Define the integration architecture, data flow, record matching logic, object and field mapping, permission model, API access approach, automation platform selection, exception handling, logging, and deployment approach. Confirm whether Salesforce EmailMessage, Task, or Event objects will be used for each activity type, and where the standard Outlook integration plus Einstein Activity Capture covers requirements versus custom Graph-based automation.
Prepare required Microsoft Entra app registrations or connectors, Microsoft Graph permissions, Salesforce connected app or API access, Power Automate or Azure Logic Apps connections, test users, pilot mailboxes, Salesforce test records, and any sandbox or non-production environment available for validation.
Configure the scoped email logging, calendar sync, task creation, reminder, approval, and notification workflows. Implement record matching rules, required field mappings, least-privilege API permissions, authentication, and basic operational logging for the integration.
Validate scoped scenarios with representative users and records, including Contacts, Leads, Opportunities, Outlook emails, calendar events, flagged emails, reminders, and exception cases. Confirm that permissions, TLS requirements, data mappings, and workflow results meet the agreed acceptance criteria.
Deploy the approved configuration to production, enable pilot or target users, run smoke testing, monitor initial executions, resolve deployment issues, and support a controlled rollout to the agreed user population — including decommissioning of any replaced Lightning Sync or Salesforce for Outlook configuration.
Provide an administrator handover covering configured flows, API connections, permissions, operational checks, and known limitations. Support covers scoped post-deployment configuration or defect issues during the agreed support window; ongoing managed support, enhancements, and SLA-backed operations require a separate agreement.

- Configure calendar event synchronization with Salesforce activities per the agreed rules.
- Enable email-triggered workflows — for example, flagging an email to create a follow-up task in Salesforce.
- Configure automated reminders for deal milestones or follow-ups based on Salesforce data.
- Build custom approval or notification workflows via Power Automate or Azure Logic Apps.
- Facilitate discovery workshops and document the agreed scope, workflows, assumptions, and acceptance criteria.
- Configure scoped components in line with least-privilege access; support testing, resolve issues related to the scoped configuration, and assist with pilot or production rollout.
- Provide handover information for administrators covering configured flows, connections, permissions, and operational checks.
Your team
- Provide access to the Microsoft 365, Exchange Online, Salesforce, Power Automate, Azure Logic Apps, and related environments required for the scoped integration.
- Assign a business owner, Salesforce or sales operations stakeholder, and Microsoft 365 or Exchange administrator for timely decisions and approvals.
- Confirm the sales process, Salesforce objects, required fields, record matching rules, email logging rules, calendar sync rules, reminder rules, and approval or notification logic.
- Provide or procure all required Microsoft, Salesforce, connector, Power Automate, Azure Logic Apps, and third-party licenses.
- Approve requested API permissions, app registrations, connected apps, mailbox access scope, and data handling requirements.
- Provide representative test users, mailboxes, Salesforce records, sample emails, sample meetings, and real-world test scenarios.
- Participate in user acceptance testing and provide timely feedback on workflow behavior, record matching, data mapping, and exceptions.
- Communicate rollout timing and usage expectations to affected users and manage internal change management or training needs.
- Maintain ownership of Salesforce data quality, duplicate management, user permissions, security policies, and compliance decisions.

Limitations & technical notes
Frequently asked questions
What is the Salesforce + Microsoft Exchange Online Integration service?
IT Partner connects Salesforce with Microsoft Exchange Online — Outlook Mail and Calendar — so sales teams can log customer communications, sync activities, and trigger sales workflows from their mailbox. The integration is built on supported components: the Microsoft Graph API for mail and calendar access, the Salesforce REST API for records and workflow actions, and Power Automate or Azure Logic Apps for automation.
We use Lightning Sync for contacts and calendars. Why does this matter now?
Because it stops working soon. Microsoft is retiring Exchange Web Services (EWS) for Exchange Online in October 2026, and Salesforce Lightning Sync depends on EWS — orgs still on Lightning Sync lose contact and calendar synchronization at that point. This service migrates you to a supported replacement, typically Salesforce's Outlook integration with Einstein Activity Capture or a custom Microsoft Graph-based sync, before the deadline.
Is Salesforce for Outlook still supported?
Salesforce for Outlook is deprecated, and Salesforce has scheduled its retirement for December 2027. Salesforce's recommended path is the Outlook integration add-in with Einstein Activity Capture for email and event capture. IT Partner helps you move off the legacy client and adds custom automation where the standard tools don't cover your process.
What Salesforce records can Outlook activity be logged to?
Outlook emails, meetings, and tasks can be logged to Salesforce records including Contacts, Leads, and Opportunities, and emails are linked to the correct Contact or Opportunity per the agreed matching rules. Email logging uses Salesforce's EmailMessage object, and activities use Task/Event.
Can Exchange Online calendar events sync with Salesforce?
Yes. Calendar events can sync with Salesforce activities per the agreed rules — including creating Salesforce tasks with reminders from calendar items where that behavior is in scope. Sync direction, conflict handling, and which meetings qualify are defined during design.
Can flagged Outlook emails create Salesforce follow-up tasks?
Yes. One supported scenario is an email-triggered workflow where flagging an email in Outlook triggers Power Automate, which creates a Salesforce Task and can include the email body as context. Trigger conditions and task fields are agreed during scoping.
Can the integration send automated reminders or route approvals?
Yes. The service can enable automated reminders for deal milestones or follow-ups based on Salesforce data, and custom workflows can route approvals or notifications via Power Automate or Azure Logic Apps, tailored to your sales process.
How is security handled for mailbox access?
The integration uses the Microsoft Graph API with least-privilege API permissions approved by your administrators, TLS 1.2+, and the Salesforce REST API through a connected app. Mailbox access scope, email body and attachment handling, and any compliance constraints are explicitly approved by the client before build.
What are the prerequisites?
A Microsoft 365 tenant with Exchange Online mailboxes, a Salesforce edition with the required API access, administrator access on both sides to approve permissions and connected apps, appropriate Power Automate or Azure Logic Apps licensing where automation is in scope, and a business owner who can confirm workflow rules and matching logic. For migrations, details of the existing Lightning Sync or Salesforce for Outlook configuration help, where retrievable.
How long does the integration take, and how is it priced?
The service is billed hourly at the published rate, with total effort scoped per project. A standard engagement is planned at five days; the final timeline depends on the logging behavior, calendar sync rules, workflow complexity, and rollout requirements.
What is not included?
License costs are excluded — Microsoft 365, Salesforce, Power Automate, and connector licenses are purchased by the client. Also excluded unless separately scoped: historical data migration, large-scale data cleanup, custom Outlook add-in development, integrations with other systems, and formal training programs. The service replaces Lightning Sync and Salesforce for Outlook rather than extending them, and ongoing SLA-backed support requires a separate agreement.
What happens after deployment?
You receive administrator handover covering configured flows, API connections, permissions, and operational checks, and IT Partner supports scoped post-deployment configuration or defect issues during the agreed support window. Ongoing managed support, enhancements, and SLA-backed operations are available under a separate agreement.
