Sync Salesforce With Outlook Calendar: A How-To Guide

Syncing Salesforce With Your Outlook Calendar

As we’ve discussed in previous blogs, the two respective CRM and email giants make a dynamic partnership – when configured correctly.

But what about Outlook Calendar and Salesforce?

Yup, they count as a separate pairing. And as you’d expect there are numerous ways of getting the most of the two tools.

Let’s consider the benefits this couple has to offer and take a look at the different ways they can complement each other.

Moving On From Legacy Software

One of the great things about using Salesforce and Outlook is the way in which pretty much every piece of sales information can be captured, linked, automated, and tracked – from a single point of reference: your favorite Microsoft email program.

Not only does using the two in tandem allow sales teams to get a complete overview of their prospects and related information, but with the right integration tools they never even have to leave Outlook – or Outlook Calendar, for that matter.

But, given that the popular Salesforce For Outlook integration tool is being retired at the end of 2027, both sales teams and Salesforce CRM admins are looking at new solutions.

While some of the more obvious candidates – such as Outlook Integration, Salesforce Inbox, and Einstein Activity Capture – all have their merits, most fall down given their incompatibility with other key software platforms such as Microsoft Office and Internet Explorer.

Similarly, given their individual features, often two or more tools need to be used to get the required functionality – making the whole process of getting up and running more complicated and time consuming.

And that’s even before you’ve considered whether or not the tools themselves sync with Outlook Calendar.

Reasons To Sync Salesforce & Outlook Calendar

When it comes to sales efforts and calendar functionality, what exactly is it that teams and Salesforce admins need to be able to do? With Salesforce For Outlook they had numerous options available.

1. Firstly, they were able to transfer information from Outlook Calendar to the appropriate individual record in Salesforce almost intuitively – all within Outlook itself.
2. The other key benefit was the ability for users to sync their calendars with Salesforce itself: enabling them to add details of scheduled calls, follow up meetings, and their own availability – whilst being able to filter out any personal or non-work related information.
3. Automation was another crucial feature. For example, if a user saw that a particular calendar entry or appointment included one of their prospects (whose information was already recorded in Salesforce) a simple click would add the event into Salesforce itself.

In these ways and others a whole lot of time and effort was saved – and a lot less work was duplicated.

However, one of the biggest criticisms of Salesforce for Outlook’s calendar integration was the fact it tended to overcompensate in terms of the wealth of information that was visible.

While the aim was to give everyone who needed oversight of contact, prospect, and team activity at a glance; the depth of insight ultimately presented its own challenges.

However, a new generation of calendar sync tools are coming through: offering improved benefits, greater time savings, and reduced admin burden.

Syncing Salesforce With Your Outlook Calendar: Options

Keeping your Salesforce and Outlook Calendar in sync is crucial for ensuring that no meetings, follow-ups, or important client interactions slip through the cracks. Fortunately, Salesforce provides several options for integration, each with its own capabilities and limitations.

Cirrus Insight – The Most Comprehensive Way to Sync

When it comes to syncing Salesforce with Outlook, Cirrus Insight stands out as more than just a simple integration—it’s a productivity powerhouse. Unlike other solutions that focus solely on syncing emails and events, Cirrus Insight provides a fully integrated sales workflow directly inside Outlook.

At the heart of Cirrus Insight is the Sidebar—a single hub that gives sales teams access to everything they need without switching between multiple apps. No more logging in and out of Salesforce, manually copying meeting details, or struggling with scheduling conflicts. Cirrus Insight keeps everything in sync and brings Salesforce directly into Outlook for a seamless sales experience.

Automatic, Reliable Syncing

Cirrus Insight automatically records and syncs sales emails, calls, meetings, contacts, notes, and even custom objects into Salesforce, eliminating manual data entry. Whether you use Outlook or Gmail, your activity is always captured in real time. Unlike Einstein Activity Capture, where data retention is limited, Cirrus Insight syncs directly to Salesforce records, ensuring long-term visibility and full reporting capabilities.

Advanced Calendar & Scheduling Features

Beyond basic email and event syncing, Cirrus Insight offers robust calendar functionality that enhances scheduling for sales teams:

• Unified Scheduling Tab – Sales reps can manage, view & share their availability in real time.

• Team Scheduling – Easily share combined team availability, perfect for coordinating meetings without back-and-forth emails.

• Instant Booking Links – Send personalized booking links to prospects, allowing them to select a meeting time without the hassle of “calendar ping pong.”

• Intelligent Lead Routing – Seamlessly connect leads to sales reps in real-time based on personalization criteria, availability, and utilization.

On-the-Go Scheduling for Sales Teams

Cirrus Insight also supports sales professionals who travel or work across multiple locations. Sales reps can configure their calendars to show their availability only in specific cities or offices, making it easy for customers to book in-person meetings when reps are nearby.

Seamless Meeting Booking Directly From Emails

One of the most powerful features of Cirrus Insight is its ability to embed a "Book A Meeting" button directly into emails. Instead of linking to an external scheduling tool, prospects can instantly access a personalized booking page with the rep’s bio, photo, and available times. This feature alone drastically increases booking rates and ensures that meetings happen at the most convenient times for both parties.

Einstein Activity Capture – Basic, but Limited

Einstein Activity Capture (EAC) is Salesforce’s built-in solution for syncing Outlook and Gmail with Salesforce. While it provides automatic syncing, it comes with key limitations:

• Data retention is limited to 6 months (or 24 months for paid tiers).

• No true data storage in Salesforce—synced events and emails aren’t stored as standard Salesforce records.

• Minimal customization, meaning users have little control over what gets synced and how.
  While EAC is an easy option for organizations already using Salesforce, its lack of control and reporting limitations can be a challenge for sales teams.

Legacy Lightning Sync – Phasing Out

Lightning Sync was Salesforce’s previous integration tool for Outlook and Gmail, but it’s now being retired in favor of Einstein Activity Capture. Users still on Lightning Sync should be aware of:

• Limited support—Salesforce is sunsetting the tool in favor of EAC.

• Setup complexity, making it less user-friendly than newer options.

• Lack of ongoing updates, meaning future compatibility issues may arise.
  For organizations still using Lightning Sync, now is the time to explore alternative solutions before full deprecation.

Choosing the Right Sync Solution

If you’re looking for a Salesforce-Outlook integration that offers full control, real-time sync, and enhanced productivity features, Cirrus Insight is the best choice. While Einstein Activity Capture and Lightning Sync provide basic functionality, they come with limitations that may impact data visibility and workflow efficiency.

By selecting the right integration tool, your sales team can save time, reduce manual data entry, and focus on what matters most—closing deals.

How to Sync Outlook Calendar with Salesforce

Sales teams rely on a seamless connection between their Outlook Calendar and Salesforce to keep track of meetings, follow-ups, and client interactions. Einstein Activity Capture (EAC) is Salesforce’s built-in tool that automatically syncs emails, events, and contacts between Outlook and Salesforce.

Step 1: Check Your Salesforce Edition & Permissions

Before setting up Einstein Activity Capture, ensure that:

• Your organization uses Salesforce Essentials, Professional, Enterprise, Performance, Unlimited, or Developer Edition.
• You have the proper permissions to configure EAC. If unsure, ask your Salesforce admin to enable the feature.

Step 2: Enable Einstein Activity Capture in Salesforce

1. Log into Salesforce and go to Setup.

2. In the Quick Find box, type "Einstein Activity Capture" and select it.

3. Click Settings and then Get Started.

4. Under Connected Accounts, select Outlook as your email provider.

5. Click Connect Account and sign in using your Outlook credentials.

Step 3: Configure Sync Settings

Once connected, customize how data syncs between Outlook and Salesforce:

• Choose the sync direction:

  • One-way (Outlook → Salesforce) – Events from Outlook are copied to Salesforce but not the other way around.

  • Two-way (Outlook ↔ Salesforce) – Changes in either Outlook or Salesforce will sync across both platforms.

• Select which activities sync: Choose whether to sync emails, calendar events, and contacts.

• Set data retention preferences: Remember that EAC only retains activity data for up to 6 months (or 24 months on paid plans).

Step 4: Verify That Syncing is Working

1. Schedule a test event in Outlook and check if it appears in Salesforce under Activities.

2. If the event does not sync, go to Setup → Einstein Activity Capture and review your connection.

3. Confirm that users are assigned the correct Einstein Activity Capture settings.

Limitations of Einstein Activity Capture

While EAC is a free and built-in solution, it has notable drawbacks:

• Data isn’t stored in Salesforce records, making it difficult to run reports on activity history.

• No customization options—users have limited control over what gets synced.

• Data retention is capped at 6 months (unless upgraded to a paid plan).

For teams needing more robust calendar syncing, better data visibility, and full Salesforce record storage, Cirrus Insight is a superior alternative.
