How to Export Your Outlook Calendar to ICS, Excel, or Google

Before you start

Which export method should you use?

Use an ICS file for a one-time calendar import, a CSV file to inspect events in Excel, or a published ICS link for a read-only subscription that can show later changes. A file import does not stay in sync with Outlook.

Export an Outlook calendar to ICS in classic Outlook

See Microsoft’s Outlook calendar export instructions for the classic Outlook controls.

Export an Outlook calendar to Excel in classic Outlook

Outlook exports a CSV file , which you can open in Excel. Save a separate .xlsx copy if you want an Excel workbook.

1. Select File → Open & Export → Import/Export → Export to a file → Next → Comma Separated Values → Next .
2. Select the correct Calendar folder, choose Next , name the .csv file, and select Finish . If Outlook asks for a date range, include the period you need.
3. Open the CSV in Excel and check the subject and date columns. To create a workbook, select File → Save As in Excel and choose .xlsx . Keep the original CSV if you may need it elsewhere.

These CSV steps are documented in Microsoft Q&A’s classic Outlook export guidance . An Excel workbook is for working with the data; Google Calendar’s event importer accepts ICS and CSV files, not .xlsx workbooks.

Get an ICS file from new Outlook or Outlook on the web

1. Open Calendar , then go to Settings → Calendar → Shared calendars .
2. Under Publish a calendar , choose your calendar and the detail level you’re permitted to share. Select Publish .
3. Use the ICS link, not the HTML link. Open the ICS link in a browser to download or save a .ics file for a one-time move. Alternatively, copy the link into a calendar app that supports subscriptions.
4. If you published only to get a file, return to Shared calendars and select Unpublish after checking the download. Leave publishing enabled if you want a subscription to keep working.

The HTML link is for viewing the calendar in a browser. If Publish a calendar is missing, your account or organization may not allow it; ask your administrator if it’s a work account, or use classic Outlook if available. See Microsoft’s calendar publishing instructions .

Move your Outlook calendar to Google Calendar

Import events for a one-time move

1. On a computer, open Google Calendar and select Settings → Import & export → Select file from your computer .
2. Choose your .ics file or a compatible .csv file, select the destination calendar, and click Import .
3. Check an older event, an upcoming event, and a repeating event against Outlook. An import is a snapshot: later Outlook edits will not update those imported events.

Google Calendar accepts ICS and CSV imports, but its import instructions note format requirements and limitations. If repeating events matter, check them closely after a CSV import; Google may treat them as separate, one-time events.

Subscribe for read-only updates instead

In Google Calendar, select Other calendars → + → From URL and paste your published Outlook ICS link. This adds a separate, read-only calendar; it does not move editable events into your Google calendar. Keep the link private and leave Outlook publishing enabled while you use the subscription. See Google’s instructions for adding a calendar from a URL .

Troubleshooting

• No “Save Calendar” or CSV export command? Check whether you’re in new Outlook or a browser. Use calendar publishing for an ICS link, or open classic Outlook for a CSV export.
• No “Publish a calendar” option? Check that you selected your own calendar. For a work account, ask your administrator whether publishing is allowed. Use classic Outlook if it’s available.
• Too few events in the ICS file? Repeat File → Save Calendar → More Options and expand the date range. Check the detail level too.
• Expected appointments missing from the CSV? Rerun the wizard, confirm the Calendar folder, and check any requested date range.
• Google processed zero events? First check whether the events are already in the destination calendar. If not, inspect the file and export it again. See Google’s import troubleshooting guide .
• Repeating events became separate appointments? This can happen with CSV imports. Try importing an ICS export instead, then check the series.
• Guests or conference details are missing in Google? Google’s event import does not bring those details over. Check important meetings individually and recreate details you still need.
• Google events don’t update after an Outlook edit? A file import is a one-time copy. For read-only updates, subscribe using a published ICS URL instead.

Other ways to use your export

Move to another calendar app

Save an ICS file, then look for Import or Add from file in the destination app. Check several events there before removing your Outlook calendar. To bring the file into another Outlook account, see how to add a calendar to Outlook.

Back up for another Outlook installation

If you’re staying with Outlook, an Outlook data file ( .pst ) may be more suitable than a calendar-only export. Don’t choose PST for Google Calendar: its event importer accepts ICS and CSV files. See Microsoft’s PST export guidance .

Use Mailbird without moving the calendar

If you’re changing email clients but keeping your Microsoft account, Mailbird’s Outlook Calendar app lets eligible users access that calendar inside Mailbird. It is not an ICS-import shortcut, and it is not included in Mailbird’s Free plan. Check Mailbird’s Outlook Calendar app guidance for availability.

Keep and check your export

Store downloaded ICS and CSV files in a private folder; they may contain meeting titles, locations, and notes. Export each Outlook calendar separately and label its file clearly. If events change after a one-time export, make a new file and check the destination before importing again.

Changing your desktop email client?

You can keep your Outlook account while trying Mailbird for email . If you want your calendar beside your inbox, check which calendar integrations your Mailbird plan includes ; exporting an ICS file does not itself add events to Mailbird.
