Outlook for web, calendars and shared calendars drop downs disappear

Niven 40

Hi, I have a user who uses outlook web using edge and when they load up the webpage and go to look at there calendars something strange happens. firstly there shared calendars do not load and the drop downs on the left hand side next to the calendar disappear after a brief moment. I have tried removing a few calendars and refreshing the browser/restarting the users machine but to no avail. Has anyone experienced this issue before ? The calendars work fine in the outlook desktop app

Outlook.com is no longer giving an option to add personal email addresses or calendar to the outlook.com calendar since January 15, 2025 (for me). It is completely out of sync. On that day, the old and wonderful, precise and nothing broken, decade's worth of precision Email & Calendar App was no longer available and replaced with the new Outlook App. I only use these for the Calendar after a coma years ago, I lost a great deal of memory, so the old App held over 12 years or more of critical information for me, including repeated events with no end date. The new replacement App is missing many of the calendars that existed in the old App (I do not know all of their names, there's a bunch of modcal calendars as well). The new App is syncing in real time with my paid for Outlook 365 calendar, but nothing is syncing with Outlook.com, thus my phone calendar, which connects to outlook.com is of no use to me any longer, and due to said coma and memory loss I need it. I've searched like crazy to find a way to add everything back to outlook.com that was there before that date but there is no function to.

There are many other issues going on with missing events, missing occurrences and more, but for now I'm just speaking of Outlook.com, which is no longer a backup for me of my calendar and completely out of date (old) and missing countless calendars found in my other 2 (new Outlook App and my paid for Outlook 365 (again both have issues, but this is about Outlook.com. Why would removing an "APP" and replacing it with another "APP" completely destroy the precisely working Outlook 365 (paid) and 100% make outlook.com no longer something either sync to and no longer serving any purpose, since all of the calendars with my information on it, which the old Email & Calendar App's Calendar synced to with one click of sync, not each calendar separately, but as a whole.

Where did our calendars go on Outlook.com, why are they missing and how do we add them back? There is literally no way for my phone calendar to tell me where I've been or need to go if Outlook.com is no longer syncing with any current information. Outlook 365 and the new Outlook App are syncing to each other, which makes no sense. I mean it's good that when you update one the other updates (again there's huge issues with Outlook 365 and the new Outlook App now but that's not the topic). Why are neither syncing precisely or at all with Outlook.com, this is crucial, people need to look at their calendars while out of their homes and the calendar on my phone is horrifically outdated since January 15, 2025, because Outlook.com is.

I look forward to your assistance, swiftly I hope, this has been madness for over a month now.

Thank you in advance,
Kimba

Hi @Niven,

Thanks for the sharing.

[Outlook for web, calendars and shared calendars drop downs disappear]

Issue: I have a user who uses outlook web using edge and when they load up the webpage and go to look at there calendars something strange happens. firstly there shared calendars do not load and the drop downs on the left hand side next to the calendar disappear after a brief moment.

Solution: This is what i Did to fix the issue. After some troubleshooting, this is what I did. Click 'Add calendar', then 'Add personal calendars'. You will see the user's email address, some broken images, and a button with 'Remove account', click that and the page goes back to where you can add a personal account. Close out, refresh the calendar, and you should be good to go. In my case, it looks like the user tried to add their work account to the same work account and Outlook didn't like that. Hopefully this will help you.

Hi @Niven

Welcome to our forum!

I would like to know what @domain and who is hosting your email account? example for @domains: Gmail.com, Yahoo.com, Outlook.com/Hotmail.com

The problem only occurs on the browser client and can be caused by some browser settings or cache issues. Here are some possible solutions you can try:

Make sure you have a fast and stable internet connection.
Clear browsing data: Go to Edge settings and select “Privacy, search, and services”. Under “Clear browsing data”, click on “Choose what to clear” and select “Cached images and files” and “Cookies and other site data”. Then click on “Clear now” and restart Edge.
Use private browsing: Open a new InPrivate window in Edge. Then go to Outlook web and sign in to your account. Check if the shared calendars load properly in this mode.
Log in with a different browser and check if there are any discrepancies.

Hi, Thank you for your response. The user is using a @outlook custom domain so it is the company's name as the @ but I have tested the user in Chrome and on a completely different laptop so a fresh session of edge with no data. still the same issue occurs. Internet wont be the issue as they are on the works network and I would have this issue with other users. I have tried incognito windows. Just about to try firefox incase its a chromium issue. But at a loss with this one ? Anymore ideas ?

Update, FireFox still didn't work. Could this be an issue with a calendar being corrupted ? or an event ? this user has a few shared calendars.

Hi

Thanks for your reply!

What does Outlook Custom Domain mean? Is this it?

Premium features in Outlook.com for Microsoft 365 subscribers - Microsoft Support.

Or is your organization using Exchange Online?
