Microsoft Outlook will no longer work with Apple Mail

Remove Outlook account in Mac Mail then add a new 'Microsoft Exchange' account using the Outlook email and password login. Worked for me. If only that had been explained by Microsoft — they only gave me information relevant to iOS.

have received an eMail from Microsoft informing me that as of September 16, 2024, I will no longer be able to access Outlook through Mail. I am required to update my Outlook access through Apple Mail, how do we do that? Can someone provide with instructions please? Also do I have to do this in each device ie, iMac, iPad & iPhone?

Why can't we get just a clear official statement from Apple/Microsoft, explaining how we make Outlook work in Apple mail. Nothing but problems for months now. I give up. I have no f... idea how to make it work. And why should I even be bothered? You made the changes, now you fix the problem, instead of dumping the problem on me. I am so tired!!!

Sonoma is later, much much later than 10.14 Mojave.

Go into System Settings ➜ Internet Accounts, and make sure your Microsoft email account shows up as an Exchange account there. If it does then you are fine.

It does affect accounts added to iPhone and iPad yes.

On your iPhone go into Settings ➜ Mail ➜ Accounts, and make sure your account appears there as Outlook, and not as Hotmail or Live. If it does, then you are fine. If it doesn't, you may need to remove it from there, and add it again using the Outlook option.

Well this is frustrating. I’ve been trying to work through this to remotely help my parents (in their 70s and not that tech savvy), and finding that I can’t sign into my own Hotmail account through Microsoft exchange using my iPad.

I tried to add the exchange account and choose sign in, rather than, manual configuration, but it doesn’t recognise the password, which I know to be correct. It accepts the log in on the first screen, but when it asks for optional domain and server info etc, it fails.

Anyone else had this problem?

Hi @Phil0124

Thanks for the helpful directive. I have verified that my live account on my iPhone is Outlook. However, I'd like to know if installing MS Outlook mobile app on my iPhone is still necessary comes Sep 16, 2024?

The MS blog link ( https://techcommunity.microsoft.com/t5/outlook-blog/keeping-our-outlook-personal-email-users-safe-reinforcing-our/ba-p/4164184) you posted on Jul 2, says MS Outlook mobile app is required.

I'd prefer to stick to one native iPhone mail app for all my email accounts rather than having 101 different mail apps on the phone: every provider pushes people to install their apps 🙄, cluttering the phone & forcing app updates **** incessantly.

Thanks for your time and help.

Yes! And someone please tell me if I will loose all my folders. Why is this not explained anywhere!!

Microsoft will continue to support Apple Mail, they just require a higher more secure level of authentication to use your Outlook.com, Hotmail.com or Live.com email accounts with it.

Apple Mail supports it fine, unless you have an older macOS version with an older version of Mail on it.

What macOS version is your Mac currently running?

To help keep Outlook personal email accounts secure, starting

September 16, 2024, Microsoft will no longer support Basic Auth, the

method in which a person provides only their username and password to

sign into their account.  As of September 16, 2024, Outlook will require

that all those with a Microsoft email account use a mail or calendar

app or the Outlook.com website which supports modern auth, such as the

latest versions of Outlook, Apple Mail, or Thunderbird.  

Deleting the current outlook account and replacing it using MS Exchange worked except it was putting all my incoming mail into the junk folder. Even after marking the items as "not junk", it kept returning them to junk. I gave up and now access my mail via web (outlook.live.com). Maybe some day Apple will revamp its app

This worked for me also. Don't select configure manually. I noticed my Outlook.com account created using 'Other mail account' in the accounts selection window defaults to IMAP which is why it is constantly prompting me for password verification. When I attempted adding the exchange account before, I chose configure manually and it prompted for simple authentication which was giving me the same issue with multiple password requests. Selecting configure automatically or 'Sign In' will prompt you with the Microsoft '360 like' authenticator. Enter your password and it should prompt you to save the new account functions. You will have to scroll down a bit and click accept on the microsoft notification and you will receive an email from microsoft about accessing functions in your mail app.

@db_3. Will this not delete all your folders in mail? I file important documents in these folders.

Since I am not certain if the software on my MacAir falls into the "or later" basket, please let me know if Sonoma 14.5 on my MacAir supports Microsoft modern authentication workflows. If not, what should I do.

Just so you know, I do have 365 on my machine, but I would rather use Apple Mail and Calendar than Microsoft's equivalent. Thus the reason I want to stick with Apple Mail and Calendar.

Also, will this impact Apple Mail and Calendar on my iPhone 15?

Many thanks in advance for your help.

Yes, exact same problem. And same frustrations. And no solution. Apple and Microsoft just pretends, that the problem is not there.
