EventFerry › Outlook recurring events not showing in Google Calendar
Outlook recurring events not showing correctly in Google Calendar
A repeating meeting can exist as a series plus individual exceptions. Imports, delayed ICS refreshes, edited occurrences, cancellations, and daylight-saving changes can therefore make one instance disappear or leave an old copy behind.
Quick fix
Open the affected occurrence and the full series in Outlook on the web. If both are correct there, determine whether Google received the calendar through a one-time import or a continuing URL subscription. Imports never update; subscriptions can lag 24–48 hours. Test the Outlook ICS link before rebuilding anything.
Match the symptom to the cause
| Symptom | Likely explanation | Next step |
|---|---|---|
| The original series appears but later edits do not | One-time import or delayed subscription | Confirm how the calendar was added |
| One occurrence is missing | That occurrence was cancelled or edited as an exception | Open that date in Outlook on the web |
| A cancelled occurrence remains | Google has not fetched the updated ICS feed | Test the link and allow for refresh delay |
| The series is duplicated | The file was imported more than once or two connections are active | Identify the Google calendar owning each copy |
| Occurrences shift after a clock change | Time-zone or daylight-saving interpretation | Use the wrong-time checklist |
1. Confirm the series in Outlook on the web
Check three things separately: the series pattern, the specific missing date, and any occurrence that was moved or cancelled. If Outlook itself is wrong, correct the source series before troubleshooting Google.
2. Determine whether you imported or subscribed
An imported ICS or CSV file is a snapshot. Google says imported events do not stay synchronized, and repeating events imported from CSV may appear as separate one-time events. Read the complete import-versus-sync explanation.
A calendar added under Other calendars › From URL is a subscription. It can receive series changes, but Microsoft documents that Gmail may wait 24–48 hours before refreshing an Outlook feed.
3. Test the Outlook ICS link
Paste the published Outlook link into a private browser window. It should return calendar data without requiring a Microsoft sign-in. If it fails, publish a new ICS link and replace the old connection. The From URL guide covers each link check.
4. Look for two copies from two different methods
Click each duplicate in Google Calendar and note its calendar name and color. One copy may belong to an earlier import while another belongs to a subscription or EventFerry calendar. Remove the obsolete calendar or connection rather than deleting occurrences individually.
5. Account for subscription delay
A changed or cancelled occurrence can remain visible until Google reads the updated feed. Wait up to 48 hours after confirming that the source and link are correct. If no part of the calendar changes after that, use the full Outlook-to-Google sync checklist.

Recurring-event questions
Why did only one Outlook meeting in the series disappear?
That occurrence may have been cancelled or changed separately from the series. Open the exact date in Outlook on the web and compare it with the series settings.
Why does Google still show a cancelled recurring meeting?
If Google receives Outlook through an ICS subscription, it may not have fetched the cancellation yet. Microsoft says Gmail refreshes can take 24–48 hours.
Why did importing my calendar duplicate the recurring meetings?
Importing is a one-time copy and does not reconcile an earlier import. Uploading another snapshot can create another set of events instead of updating the first set.
