Question

Mijn outlook agenda is ineens leeg

Bieke Luypaerts 0

Hello

I need help recovering my Outlook.com (Hotmail) calendar.

During the week of 15 June 2026, all of my calendar appointments disappeared without any action on my part. The calendar had been working normally until then.

Here are the details:

I use a Hotmail/Outlook.com account.
All calendar events are gone, including appointments from many years ago as well as future appointments.
My emails are all still present; only the calendar has been affected.
I use the standard Outlook calendar only. I do not sync my calendar with iCloud, Google Calendar, or any third-party calendar applications.
The problem appears on all of my Apple devices and also in Outlook on the web, so this does not appear to be a device synchronization issue.
A shared calendar had to be shared with me again, but even after re-sharing, only part of the shared calendar is visible.

Could you please investigate whether my calendar data can be recovered?

Specifically, I would like you to:

check the server logs for changes around 15 June 2026;
determine whether the calendar was accidentally deleted or corrupted;
perform a server-side restore of my Outlook.com calendar, if possible.

Thank you for your assistance.

Hi Bieke Luypaerts,

I understand how concerning it is when many years of Outlook.com calendar events suddenly disappear, especially when the issue also appears in Outlook on the web and not only on Apple devices.

Please note that this is a user-to-user forum, so contributors here cannot access your Outlook.com mailbox, check server logs, or perform a server-side calendar restore. However, before contacting Outlook.com support, please try these checks:

Sign in at https://outlook.live.com/calendar using the affected Hotmail/Outlook.com account.
In Calendar, make sure all calendars under My calendars, Other calendars, and Shared calendars are selected.
Use the calendar search box to search for a few known event titles, locations, or dates.
Go to Mail > Deleted Items, then select Recover items deleted from this folder and check whether any missing calendar items appear there. If found, select the items and choose Restore.

If the missing calendar items are not visible there, this likely needs Outlook.com support to review from the service side. When contacting them, include the affected date range, for example “all calendar events disappeared around the week of 15 June 2026,” and mention that the issue also occurs in Outlook on the web.

You can contact Outlook.com support this way:

Go to Outlook.com and sign in.
Select the Help icon, the question mark, in the upper-right corner.
In the Help pane, search for account management or calendar recovery, then press Enter.
Scroll down to Still need help? and select Yes.
Choose Chat with a support agent in your web browser.
Review the issue description and confirm an email address you can access.
Select Confirm to submit the request and connect to Outlook.com support.

Please avoid posting your full email address or any private account details publicly in the forum. I hope this helps point you to the most appropriate recovery path.
