Calenda missing

Question

My calendar has all gone missing, nothing is working to bring it back including events from the past 10 years and all

future events

Answer 1

Got it, sorry to hear that.

If nothing shows on the web or in Deleted Items, Microsoft no longer has your events on the server. The only options are to check for any backups or exported calendar files you might have.

Answer 2

I cant see any events on the web too or in any deleted folder I don’t know what to do anymore

Answer 3

Unfortunately I can’t see any events even on the web or nothing in deleted wish I could fix this its so stressing I have tried a lot of things with no luck

Answer 4

Hi, happy to help here.

Please sign in to Outlook on the web and check Calendar, then make sure your calendar is selected under “My Calendars” and check the Deleted Items folder for removed events. If your calendar is also empty on the web, this means the events are no longer on Microsoft’s server.

If they appear on the web but not in the app, remove and re-add your account in the Outlook app.

Let me know what you see on the web version, so we know if this is a sync issue or account data issue.

Answer 5

On Outlook for mobile (iOS/Android), only a limited date range of calendar events is stored and shown in the app. Older items and some far‑future items will not appear, but they are not deleted and can still be viewed in other clients such as Outlook on the web or the desktop app.

On a mobile device:

• For Outlook.com, Exchange, and Microsoft 365 accounts (Exchange ActiveSync): only events from the past 2 weeks are shown; all future events are shown.
• For Google and iCloud accounts: only events from the past 2 weeks are shown; future events are shown only up to 6 months ahead.

On a Windows 10 PC using the Mail and Calendar app:

• For Outlook.com, Exchange, and Microsoft 365 accounts: events from the past 3 months are shown; all future events are shown.
• For Google and iCloud accounts: events from the past 3 months are shown; future events are shown only up to 6 months ahead.

Recurring events may appear outside these ranges if any occurrence falls within the visible window. To see older than 2 weeks/3 months or farther than 6 months ahead (for Google/iCloud), open the same calendar account in Outlook on the web or another full Outlook client; the events should still be present there.

If specific shared Google calendars are missing in Outlook for iOS/Android, ensure they are enabled in Google’s sync settings at https://calendar.google.com/calendar/syncselect, wait at least 20 minutes, then recheck the calendar list in the Outlook mobile app.
