Common Causes

Recurring calendar events are designed to save time, but they can occasionally misbehave after edits — particularly when changes are made on one device and don't sync cleanly to others. This guide walks you through resolving the most common issues we see across Outlook (desktop and web), Google Calendar, and connected mobile devices. Most cases are fixed by forcing a sync refresh, clearing cached calendar data, or recreating the affected series.

Quick Fix Steps

Before diving into detailed troubleshooting, try these steps first — they resolve the majority of recurring event issues:

  1. Force a sync refresh on the device showing the wrong date (instructions below per platform).
  2. Open the event in Outlook on the web or Google Calendar in your browser and check whether the issue exists there too. This tells you if the problem is with the calendar source or a single device.
  3. Remove and re-add the affected recurring event series.
  4. Restart the calendar app or device.

Identify Where the Problem Lives

The first step is working out whether the issue is with the calendar source itself, a sync problem, or a single device displaying stale data.

Check the calendar source

  1. Open Outlook on the web (outlook.office.com) or Google Calendar (calendar.google.com) in a desktop browser.
  2. Locate the recurring event in question.
  3. Open the event and review the date, time, and recurrence pattern.

If the event looks correct in the web view, the issue is almost certainly with a single device or app cache. If the event looks wrong in the web view too, the problem is with the calendar source and you'll need to edit the series from there.

Force a Sync Refresh

Outlook desktop (Windows)

  1. Click Send/Receive in the ribbon.
  2. Click Send/Receive Groups > Send/Receive All Folders. You can also press F9.
  3. Wait for the status bar to show "All folders are up to date".

Outlook desktop (macOS)

  1. Make sure Outlook is the active window.
  2. Click Send/Receive in the toolbar, or press Ctrl+Command+K.

Outlook on mobile (iOS and Android)

  1. Open the Outlook app.
  2. Pull down on the calendar view to trigger a manual sync.
  3. Alternatively, close and reopen the app completely.

Google Calendar on mobile

  1. Open the Google Calendar app.
  2. Pull down on the main calendar view to refresh.
  3. If that doesn't work, force close the app and reopen it.
If your mobile device uses the native calendar app (Apple Calendar or Samsung Calendar), the refresh behaviour depends on the account type. For Microsoft 365 accounts, the Outlook app typically provides more reliable sync than the native iOS Calendar app.

Edit the Recurring Series Correctly

One of the most common causes of recurring event issues is editing a single occurrence instead of the entire series, or vice versa. Outlook and Google Calendar handle this differently.

In Outlook (desktop and web)

  1. Double-click the recurring event to open it.
  2. You'll be prompted: "Open this occurrence" or "Open the series". Choose "Open the series" when you want changes to apply to all future events.
  3. Make your changes and click Save.
  4. If prompted about existing occurrences, choose "Update all occurrences" rather than "Update only this one".

In Google Calendar

  1. Click the recurring event to open the pop-up.
  2. Click the pencil icon to edit.
  3. By default, Google will ask whether to save changes to "This event" or "This and following events" or "All events". Choose the option that matches your intent.
If you edit only a single occurrence and later edit the series, Outlook may revert your single-occurrence change. Always document custom exceptions before making series-wide edits.

Clear Calendar Cache

Sometimes the calendar app displays cached data even after a sync. Clearing the cache forces the app to pull fresh data from the server.

Google Calendar (web)

  1. Click the gear icon in the top right.
  2. Select Settings.
  3. Click Trash in the left sidebar.
  4. Optionally, empty the trash to remove deleted events permanently.

Outlook desktop (Windows)

  1. Close Outlook completely.
  2. Press Windows+R, type %localappdata%\Microsoft\Outlook\RoamCache, and press Enter.
  3. Delete the contents of the folder (not the folder itself).
  4. Restart Outlook.

Outlook on mobile

  1. Open the Outlook app.
  2. Tap your profile icon > Settings.
  3. Under Mail, tap the affected account.
  4. Toggle the account off, wait 10 seconds, then toggle it back on.

Remove and Re-add the Recurring Event

If the event still displays incorrectly after a sync refresh and cache clear, the cleanest fix is to delete the series and recreate it.

In Outlook

  1. Open the series (not a single occurrence).
  2. Click Delete in the ribbon.
  3. Choose whether to delete "All occurrences" or just past ones.
  4. Create the event again from scratch, paying close attention to the recurrence pattern, time zone, and end date.

In Google Calendar

  1. Click the event to open the pop-up.
  2. Click the three-dot menu > Delete event > All events in the series.
  3. Create a new event with the correct recurrence.
Before deleting, export or screenshot the event details so you can recreate it accurately. If the event was set up by someone else, coordinate with them first.

Check for Time Zone Issues

Recurring events that cross daylight saving boundaries or were created in a different time zone are a frequent source of "wrong date" complaints.

  1. Open the recurring event and check the time zone listed in the event details.
  2. Compare it to your current time zone setting in the calendar app.
  3. In Outlook, go to File > Options > Calendar > Time zones to verify your default.
  4. In Google Calendar, click the gear icon > Settings > Time zone to confirm your primary time zone.

If the event was created in a different time zone and you need it to follow your local time, edit the series and update the time zone field.

Check Sync Between Connected Calendars

If you have both an Outlook and a Google Calendar account connected (for example, via a third-party sync tool or by subscribing to each other's calendars), conflicts can occur when the same event is edited in two places.

  1. Decide which calendar should be the "source of truth" for the event.
  2. Make all edits in that calendar only.
  3. Allow the sync tool to propagate changes to the other calendar.
  4. Avoid editing the same event in both calendars within a short window.
Two-way sync tools can create duplicate events or conflicting recurrence patterns. If you're using one, check its logs or dashboard for sync errors before making further manual edits.

When to Escalate

If the recurring event still shows the wrong date after completing all of the steps above, gather the following information before contacting support:

This information will help support diagnose whether the issue is account-specific, related to a sync tool, or a known platform bug.
