How to Convert OLM to ICS File Format? Top Methods

If you are running a business, it would be quite difficult to track meetings, project deadlines, and appointments. What makes it even more difficult is losing them once the platform is changed. Many Mac Outlook users are troubled while sharing calendar data across different platforms, as it stores data in an OLM file. However, if you convert OLM to ICS, transferring the Outlook calendar to Google Calendar, Apple Calendar, or any CRM can be easier. ICS is a universal calendar file format. Explore the manual route or a professional Cigati OLM Converter Tool discussed in this blog to transfer data efficiently.

Why Convert OLM File to ICS File?

Don’t you wonder why ICS is preferred by businesses and professionals? It’s because of the following reasons:

• Access to ICS across multiple platforms is the primary cause. ICS is supported across Google Workspace, Thunderbird, iCloud, Office 365, and more.
• .ics file helps companies to migrate all important calendar data, including events, meetings, and deadlines, without disruption. 
• Moreover, the ICS format ensures all your data, such as client meetings and records, is preserved securely. Hence, maintains compliance and security. 
• Unlike OLM, you can easily share ICS files with team members, partners, or clients, no matter what platform they use. 

Well, converting OLM to ICS helps your business to access schedules easily, share them, maintain workflow, and keep a backup ready. So, be ready and find a method best suited for large data sets further. 

Can I Export ICS from Outlook for Mac Directly?

Yes, but only when you know the exact procedure. However, Mac Outlook stores calendars saved in an OLM file, which is a proprietary database. This means OLM is not directly supported by any other platform. Additionally, unlike Windows Outlook, there is no built-in Save as ICS option to convert all events at once. 

Therefore, users have to extract calendar data manually in ICS or use specialized software. Let’s explore both options.

How Do I Convert OLM to ICS? – Top 2 Ways

In this section, we will discuss two types of methods: one that requires no money but also has many limitations. On the other hand, a professional solution is secure as well as trusted by professionals. Let’s find out which suits your conversion requirements best. 

Method 1: Free Method to Convert Mac Outlook OLM to ICS

Firstly, note that this procedure is suitable for those looking to migrate a few calendar events or who need to export specific data. Manual approach is not a good practice for multiple OLM files or large data sets. Follow the stepwise procedure given:

1. Launch the Mac Outlook application on your Mac system.
2. Open the Calendar view.
3. Select the event or set of events that you want to export.
4. Simply drag the selected events from Outlook Calendar and drop them onto your Mac desktop.

Hence, each exported event will be saved as a separate .ics file. Afterward, share or import these into other email clients or cloud platforms. However, like all manual methods, this too has certain limitations. Have a look first.

Limitations of Manual Method

• It does not allow exporting all calendar events at once.
• Also, takes lots of time, especially for large or multiple OLM files.
• Difficult to export event metadata or recurring events correctly.
• And most importantly, it’s not suitable for business-scale migration.

So, while this method is fine for personal use, business users or IT teams need something more reliable, fast, and scalable.
