Question

Calendar items wiped - can't find them - tried methods to restore - Please HELP!

NPD _29 0

Earlier today (11/14/26, US location) I received a notification that my account password needed to be re-entered. When I went to my accounts on my iphone (17Pro) there was no message anymore, however, in past experience this issue doesn't allow new messages to come through, so I deleted my accounts (both Hotmail) from my phone and re-added them (no issues doing this in past and all items were fine before I did this). When I went to my calendar all items for these accounts were gone and aren't online when I login to my account. I create calendar invites on my iphone in the calendar app and never from the online calendar version. How can I restore these or will Microsoft correct this issue? These are all health appts that are super important and that I don't have info for anywhere else (guess I should go back to paper and pen so I'm not left blind in future). Please HELP!

Thank you!!

Answer 1

I enter all calendar invites the same way - open iphone calendar app, enter details/info, save, then choose color to signify it's importance (each color is linked to 1 of my 2 hotmail accounts, gmail, and iCloud). I've always done it this way and have deleted my accounts and re-added in past due to being compromised and never lost any events. I have done all of the suggestions to find them and for some reason can't figure out if my account is being stored locally or synced. I use my calendar as my notes app as well bc in past I used apple notes and it deleted them all, so I felt this was safer. Now I don't feel anything digital is safe and want to go back to pen and paper:( I not only had health appt's in there, I had logs for those appts, kids schedules for every sport, and their appts. This was what I lived and died by. There has to be a way to restore it bc nothing is in my deleted items folder, online, in my app or on iCloud, so where did they go? Could this be related to the outage? Is there a synced area that could be delayed?

Hi @NPD _29

I understand how serious this is, especially when the missing entries contain important healthcare appointments.

One additional recovery route is to check whether any of these appointments generated outgoing invitations. Search the Sent Items folder of both Hotmail accounts for the provider’s name, email address, appointment title, or words such as “invitation” and “appointment.” If another person or medical office received an invitation, ask the recipient to forward the original invitation back to you. Accepting it again may restore the event to the correct calendar.

You should also check any patient portals, confirmation emails, text messages, or telephone records associated with the healthcare providers. The providers can usually confirm the scheduled date and time even if the original calendar entry cannot be recovered.

Because the entries were already absent from Outlook.com, there is a possibility that they existed only as locally cached calendar data on the iPhone and were removed when the accounts were deleted. Please avoid removing and re-adding the accounts again, as doing so will not recover locally stored data.

For future events, you can verify where new appointments are being saved under Settings > Apps > Calendar > Default Calendar on the iPhone. Selecting the intended Hotmail calendar helps ensure that new entries synchronize with Outlook.com rather than remaining under another calendar.

I hope you are able to reconstruct the appointments from the sent invitations or provider records.

Answer 3

Because the appointments are also missing from Outlook.com, attempt server-side recovery from a computer immediately, then contact Outlook.com Support if the items are not recoverable.

1. Recover the appointments from Outlook.com

Repeat these steps separately for each Hotmail account, using a PC or Mac browser rather than an iPhone or mobile browser:

Sign in to Outlook.com with the first affected account.
Open Mail, then select Deleted Items in the left pane.
Look for the missing appointments. If present, select them and choose Restore.
If they are not visible, select Recover items deleted from this folder above the message list.
Select the calendar items and choose Restore. Outlook restores recoverable calendar items to the Calendar folder.^1^
Open Calendar and check the relevant dates.
Sign out and repeat for the second Hotmail account.

Use a computer because the Recoverable Items area cannot be accessed through Outlook mobile apps or a mobile browser. Recoverable items are time-limited, so do this now.^1^

2. Check which account actually stored the appointments

Creating an appointment in Apple Calendar does not by itself establish that it was saved to Hotmail. Apple Calendar can save events under Outlook, iCloud, or another calendar.

On the iPhone:

Open Calendar.
Tap Calendars at the bottom.
Note every listed calendar and account—particularly Outlook/Hotmail, iCloud, and any On My iPhone entry.
Select all available calendars temporarily and check the appointment dates.

This account check is specifically recommended for an iPhone calendar that disappears while its Outlook.com copy is also missing.^2^

If the missing events belonged to iCloud, use iCloud.com → Data Recovery → Restore Calendars. Review Apple’s warning first: restoring an archived calendar version replaces the calendars currently held in iCloud and removes calendar-sharing settings.^2^

If they were stored only locally on the iPhone and no longer exist there, Outlook.com cannot restore them because Microsoft never held that data.

3. Escalate to Outlook.com Support

If the appointments belonged to either Hotmail calendar but are absent from both Calendar and Recoverable Items:

While signed in to that Hotmail account on Outlook.com, select Help.
Enter a description such as:
“All Outlook.com calendar events disappeared on November 14, 2026 after removing and re-adding the account on iPhone; events are absent on the web and not available under Recover items deleted from this folder.”
At Still need help?, select Yes and submit the request.
Submit a separate request for the other account if both are affected.

That is the supported escalation route for account-side Outlook.com calendar loss.^3^

There is no published Microsoft notice in the available known-issue information identifying this exact November 14, 2026 symptom as a confirmed Outlook.com incident.^4^ A service correction therefore should not be treated as the recovery plan.

Since removing and re-adding both accounts has already been completed, do not repeat that process while pursuing recovery. For imminent medical appointments, contact the providers directly now; neither recovery nor support escalation guarantees that the entries can be returned in time.
