Salesforce + Microsoft Outlook Integration — CRM Activity Sync & Sales Workflow Automation
Salesforce + Microsoft Outlook Integration connects Outlook — desktop, web, and mobile — with Salesforce so sales teams can log customer emails, sync calendar activity, and trigger sales workflows without switching systems. The legacy Salesforce for Outlook add-in is deprecated and retires in December 2027, and Lightning Sync ends with Microsoft's Exchange Web Services retirement in October 2026 — so IT Partner implements the supported stack instead: Salesforce's Outlook integration add-in with Einstein Activity Capture where it fits, plus custom automation on the Microsoft Graph API, Salesforce REST API, and Power Automate for the workflows the standard tools do not cover.
What this engagement is
This service connects Microsoft Outlook desktop, web, and mobile with Salesforce: email logging to Salesforce records, Outlook calendar synchronization with Salesforce Events or Tasks, workflow triggers from flagged emails or calendar events, actionable buttons in Outlook, and advanced automations built with Power Automate. The tooling landscape has changed, and this service is built around it: Salesforce for Outlook — the legacy installed add-in — is deprecated, with retirement scheduled for December 2027, and Lightning Sync stops working when Microsoft retires Exchange Web Services (EWS) for Exchange Online in October 2026. Salesforce's current recommendation is the Outlook integration add-in paired with Einstein Activity Capture for email and event capture. IT Partner implements that standard path where it covers your requirements, migrates orgs off the retiring tools, and builds custom Microsoft Graph and Power Automate automation for what the standard tools don't do — flagged-email task creation, approval triggers, SLA reminders, and custom field mappings. The Microsoft Graph API and Salesforce REST API are the supported API surfaces used throughout.
Success criteria
What you receive
How the work unfolds
Confirm business objectives, user groups, Salesforce objects, Outlook scenarios, required automations, security requirements, and acceptance criteria. Identify any Salesforce for Outlook or Lightning Sync usage that must be replaced before the October 2026 EWS retirement or the December 2027 Salesforce for Outlook retirement.
Validate Microsoft 365, Outlook, Salesforce, Power Automate or middleware prerequisites; confirm licensing; collect required admin access; and identify test users, sandbox environments, and deployment constraints.
Document where the Outlook integration add-in with Einstein Activity Capture covers requirements versus custom automation. Define email logging rules, calendar synchronization behavior, Salesforce Lead/Contact/Opportunity matching, EmailMessage and Task/Event usage, custom field mappings, duplicate-handling expectations, and workflow trigger logic.
Deploy the Outlook integration add-in and Einstein Activity Capture where in scope, and connect custom components using the Microsoft Graph API and Salesforce REST API with the required OAuth 2.0, connected application, consent, and permission configuration.
Configure email and event logging via the standard tools or Power Automate/custom middleware, using Salesforce EmailMessage for email logging and Task/Event for activities. Configure flagged-email task creation, follow-up reminders, SLA reminders, deal approval triggers, or other approved automations.
Run technical validation and business user acceptance testing for authentication, record matching, email logging, calendar sync, workflow triggers, custom fields, error handling, and auditability.
Deploy to an agreed pilot group or production users, monitor initial usage, resolve scoped defects, decommission replaced legacy components, and adjust configuration within the approved scope.
Provide administrator handover notes, review operational procedures, and deliver the agreed post-deployment support period. 24/7 support, continuous monitoring, ongoing maintenance, or SLA-backed support is not included by default and is available as an optional extra-cost add-on through IT Partner's NOC, third-party support partnerships, and a Microsoft Premier Support agreement.
Prerequisites

Frequently asked questions
What is the Salesforce + Microsoft Outlook Integration service?
IT Partner connects Microsoft Outlook — desktop, web, and mobile — with Salesforce so sales teams can log customer emails, sync calendar activity, and trigger sales workflows from Outlook. It combines Salesforce's supported Outlook integration add-in and Einstein Activity Capture where they fit with custom Microsoft Graph and Power Automate automation for the workflows the standard tools don't cover.
Which Salesforce Outlook tools are retiring, and what replaces them?
Salesforce for Outlook, the legacy installed add-in, is deprecated with retirement scheduled for December 2027. Lightning Sync stops working when Microsoft retires Exchange Web Services for Exchange Online in October 2026. Salesforce's recommended replacement is the Outlook integration add-in with Einstein Activity Capture — which is exactly what this service implements, plus custom automation where needed.
Can emails from Outlook be logged to Salesforce records?
Yes. Outlook emails can be logged to Salesforce and attached to Leads, Contacts, or Opportunities. Custom logging uses Salesforce's EmailMessage object, keeping a complete customer activity history in Salesforce; where Einstein Activity Capture is used, captured emails surface on the activity timeline per its data model, which is reviewed during design.
Can Outlook calendar events sync with Salesforce?
Yes. Outlook calendar activity can be synchronized with Salesforce Events or Tasks, so meeting activity is available in Salesforce without manual re-entry. Sync rules, direction, and which meetings qualify are agreed during scoping.
Does the service work with Outlook desktop, web, and mobile?
Yes. The Outlook integration add-in runs across supported Outlook desktop, web, and mobile clients, and IT Partner scopes the configuration based on your environment, tenant add-in policies, and required workflows.
Can the integration trigger Salesforce workflows or approvals from Outlook?
Yes. IT Partner can configure triggers such as flagged emails creating Salesforce follow-up tasks, calendar events syncing as activities, SLA reminders based on email responses, and optional multi-step approvals — for example, Outlook replies triggering Salesforce approval processes. Exact logic is confirmed during scoping.
Does the service use Power Automate?
Yes, where automation is in scope. Power Automate handles email and event logging scenarios and advanced automations; custom middleware is used where the design requires it. Appropriate Power Automate licensing, including premium connectors where applicable, is a client-side prerequisite.
Can the integration support Salesforce custom fields?
Yes. Custom fields are supported, with the specific fields, mapping rules, validation logic, and workflow behavior reviewed during scoping so the integration matches your Salesforce configuration.
What are the prerequisites?
A Microsoft 365 tenant with Exchange Online, a Salesforce environment with API access, administrator access on both sides, defined business rules for logging and matching, test users or a sandbox, and Power Automate licensing where automation is in scope. Einstein Activity Capture availability depends on your Salesforce licensing and is confirmed during discovery.
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 required logging, calendar sync, workflow triggers, approvals, and automation complexity.
What is not included?
License procurement, major Salesforce redesign, bulk historical email backfill, CRM data cleanup, custom application development beyond the approved design, broad end-user training, and advanced reporting are excluded unless separately scoped. The service replaces the deprecated Salesforce for Outlook and Lightning Sync rather than maintaining them. 24/7 support, continuous monitoring, and ongoing maintenance are optional extra-cost add-ons.
What happens after deployment?
You receive administrator handover notes and the agreed post-deployment defect support for the scoped configuration. Ongoing managed support, monitoring, and SLA-backed operations are available as optional extra-cost add-ons delivered through IT Partner's NOC, third-party support partnerships, and a Microsoft Premier Support agreement.
Who should use this integration service?
Sales teams, managers, and operations teams that use Salesforce and Outlook daily — especially organizations that need one-click email and meeting logging, better Salesforce activity history, fewer manual CRM updates, or that still run the retiring Salesforce for Outlook or Lightning Sync and need a supported replacement.
