Appointments/Events have vanished from my Outlook calendar

I continue to have these issues throughout the years 2023 and 2024.

I really wish there was a solution or at least a direction to work towards resolving this issue.

I'm missing events from 2008-far into the future, daily, weekly, monthly stand alone, all day, scheduled times, reoccurring daily, reoccurring weekly and reoccurring yearly. Birthdays are missing, people passing are missing, me living in hospice with my father for near 2 weeks and all I said about it on my calendar MISSING. A surgery that killed me and the bring me back to life surgery 9 years ago missing! They are missing from outlook.com (the worst of the missing is on outlook.com - but also missing from my paid for outlook 360 calendar - both of which always backed up in 100% perfect sync with my Email & Calendar Apps Calendar. How DARE Microsoft remove the use of the Calendar today, which held decades worth of information, replace it with this non-functioning duplicate of what I already pay for, have it lose more data than it has, and then have outlook.com and outlook 360's calendar missing all of the information as well. I went through cancer and multiple losses, and then a coma in a decade ago and my Email & Calendar App's "CALENDAR" was the ONLY source of memory of my daily, weekly and yearly events for all things, appointments, birthdays, people dying, ME LIVING IN HOSPICE WITH MY FATHER IN SEPT 2023, major and critical appointments, past, current and future - how dare they remove the perfect app, and then destroy the 2 fully functioning "as backups" products (outlook 360 calendar and outlook.com) before ensuring all the data was there? I have NO other resource for this information, my entire life is in that Calendar, which they provided NO download or export for before taking it away and destroying the only other 2 backups. They need to put the Email & Calendar App's Calendar BACK UP AND WORKING, until they can act like professionals and ensure this life destroying mess for all of their customers and clients, paid and otherwise, is worked out! This is going to become a legal issue, they've lost people's life & work data, decade's worth - the Email and Calendar App's "Calendar" was perfect, working perfect, did all things, saved all things, synced with everything perfectly (outlook.com, outlook 360 and my phone), did what you wanted, not what MS wanted - didn't look like the same product I already pay for - yet they removed it against my wishes and a year's worth of feedback with NO response - and LOST MY ENTIRE LIFE'S HISTORY AND FUTURE EVENTS? This isn't okay! They didn't even provide an export or save as feature for the Email & Calendar App's "Calendar" before doing this. How dare they? If Steve was still with us (RIP) he'd fire them all. Kindly give them this feedback, because what they've done is criminal, and for NO GOOD REASON! They had NO good reason for removing that App at all, in general, we still have "choices" in this country last I checked, MS isn't God and everyone was begging them not to, yet they didn't care - and now this horrific mess, everyone's lost data, me having no memory from a coma and the Email & Calendar App's "Calendar" housed it all, I don't know where I have to be tomorrow, the day after, week after, month after or year after. I don't know how many days I spent in hospice with my father a year and a 1/2 ago or what it was I wrote about it on the event in my calendar, this is UNCACCEPTABLE, including my event of the hospital killing me 9 years ago and the bring me back to life ICU event for 6 weeks, followed by 8 years of IMMENSE recovery, with all the doctor appts on that calendar. I'm getting calendar reminders on my phone that are completely out of sync and wrong - BRING BACK THE EMAIL & CALENDAR APP'S "CALENDAR" AND LET YOUR CLIENTS AND USERS DECIDE. SO HELP ME if I don't get my data back on "at this point ANY calendar," and correctly - LAWSUIT for removing the life events of a disabled woman who relied on this product, that worked perfectly, and MS removed all the data because they didn't think, test, prepare, or do ALL things they should have before taking away our right to use the Calendar of our choice and forcing 3 different versions of MS Calendars that are now missing everyone's information - in my case, 3/4 of my memory going back to near 2008 and far into the future! UNACCEPTABLE. There was no reason to do this! There is no reason to do this! No one wanted this! If "one" of my calendars isn't correct and housing ALL of my events from 2008 through to forever, and correctly, and not duplicated, and not out of whack, I'm proceeding with legal council and I want a full refund of my MS 360 paid for, and now useless to me. I can get a "word" like program elsewhere - they even destroyed Word, they've destroyed all of their products without caring about their customers and user base, but the CALENDAR?!?! That is LIFE and WORK destroying for everyone. PUT THE EMAIL & CALENDAR APP'S "CALENDAR" BACK UNTIL YOU FIX THIS MESS - THAT'S WHERE ALL OF MY EVENTS FOR LIFE ARE STORED, AND WHILE YOUR'E AT IT - PROGRAM IN A WAY TO EXPORT AND SAVE IT LOCALLY FOR FUTURE USE WHEN MS SCREWS UP THIS BAD AGAIN!!!! LAWSUIT!

Might I ask if you're speaking of Outlook 360's calendar or Outlook.com's calendar, because the removal of the Email & Calendar App's "Calendar" today just lost my entire life for decades, I'm devastated, I suffered from a coma and much more and I used the Email & Calendar App's "Calendar" as a memory tool for me, I can't get to appts, remember birthdays, when someone passed, when I was in surgery, what I have to do tomorrow, etc., decades worth. I don't see a deleted folder for calendar items in my paid for outlook 360 calendar, or on outlook.com's calendar, so I'm a bit confused about this. And they've literally destroyed outlook.com's calendar worse than my outlook 360's calendar, but both are totally destroyed and missing everything I need to remember for not just tomorrow, the next day, week, month and year, but from the past as well. If you can please share more about this deleted calendar folder I'd greatly appreciate it.

You also mentioned making a backup, but the Email & Calendar App didn't give you the option to backup, export or save your calendar locally, so there was no way to backup my entire calendar or even a portion of it. I'm devastated. I'm getting reminders on my phone, which was synced with outlook.com, which was synced with my Email & Calendar Apps's Calendar that are completely off on date and time - so now they've also messed up my phone calendar and reminders. This is awful. Any information as a fellow person hurt by this would mean the world to me. Thank you so much in advance.

All my events / appointments/notes from my outlook calendar has disappeared - This is a very big issue

as these are weekly and monthly continuous notes that is updated

This has never happened to me. I am very upset that this has happened. I have all of our appointments on this calender up to a year from now. Please help me. If you can call me that would be the best ***

This just happened to me after a windows update. Dozens of medical appointments just disappeared. Thanks Microsoft, for screwing me over and making this trying time in my life even worse.
