Unable to add Exchange email address in Apple Mail on Mac

Outlook.com is not listed here.

I spoke with Apple and troubleshooted this extensively, the issue appears to be with Microsoft as I had no issue connecting new devices earlier this year. Microsoft Exchange is the correct option as well. Outlook.com was removed and it was consolidated into the Exchange option. The pop up for me that portals through to Microsoft is failing to populate.

Seconding what others have said. This used to work fine selecting Exchange, but something is preventing the log in pop from even loading now.

Unfortunately Outlook.com no longer appears in the named accounts only Microsoft Exchange and I found trying to add my account manually also didn't work

It's been a bad couple of weeks for Apple users, I've resorted to using their Feedback Website to inform apple of these problems.

What macOS version are people using? I am using Monterey on MacBook and the Mail App works fine with Outlook.com. Recently got new MacBook running Sequoia 15.1.1 and did migration from older Monterey MacBook. Mail App with Outlook.com continued working. Then did second migration under Sequoia 15.6 and Mail App would not verify to use Outlook.com, it was disabled. So I deleted my Outlook.com account to try and add it back, which worked in the past with macOS upgrades. Now like described in this thread that fails. Maybe the version of macOS is involved some how?

I'm using Tahoe and Sequoia. One of my machines stopped getting mails and then would not let me back in. Others are still working. I suspect there maybe a trust which is letting existing connections work, but I don't recommend deleting and trying to re-add. The current Mac Mail client does not offer outlook as an option - only exchange.

Since Pavel indicated using "Outlook.com" as choice for adding Email account, but it is ONLY available under iOS, I gave it a try. After entering my Email account info the next window is the normal login process for Outlook at outlook.live.com. Entered password and shortly after I had access to my Outlook Email account on my iPhone. So we just need that capability to work under macOS like it had been.

Dave, On my newer Sequoia macOS, the existing Outlook Email account was marked as disabled recently with the circled tilde. I tried several times to reenable it, but the login verification process just kept failing. It behaved just like when trying to add an account: Window overlays where info was entered, then pops up box about verification failed, then another box about try again later. Arshia posted picture of that end state. The Outlook account was useless in that state. So after web research and my own past experiences I decided to delete the Outlook account and try adding it back. Now stuck like everyone else :-(

I think this is an apple issue and I would recommend posting feedback and also contacting support. I spoke to them, but like so many times these days the suggestion was to re-install macos. Hopefully if we all complain it will be fixed. They cannot open external web pages but you can print this thread to a pdf and upload that on a chat to Apple.

Dave, what is the Apple feedback posting I can follow up in or just start another one? I may try using an external drive to do a fresh macOS install just to see if that actually helps, not that we would all want to start over.

You have to start a fresh one - I don't know if they pay much attention to them but it's worth a try.

Ok - some encouraging news. I have just spoken to a senior Apple support advisor and they are aware of this issue and working on it. No idea how long it will take for them to fix it however.

Dave, Good to know about work being done. I'm in the process of poking Apple support about this issue to maybe turn up the heat :-)

You had mentioned using Sequoia and Tahoe with one not working with Outlook. Care to share which one had stopped working for you so I can consider a fresh test install?

Sequoia stopped initially - found i could not add account back after removing it. So I then updated that same machine to Tahoe in a vain attempt to resolve the problem but it did not help. Eventually it turned out to be a combination of a external change by Microsoft combined with a odd omission from Apple which had presumably gone unnoticed because people could have managed to use the manual method to add accounts whilst the smtp and imap authentication were working at the Microsoft end.

I have talked to Apple support, like you encountered they suggested the less severe idea of updating to the latest version of sequoia, which I will probably try. At this point my new MacBook is essentially a testbed and I will probably wipe it and start over when things are in a better place.

Your latest details about the issue sound encouraging and make sense. On Monterey I may have used the manual method a couple years ago when MS updated Outlook requirements to use Modern Verification eliminating the use of ID+PW. It is hard to tell in the Mail App how the account is currently setup; Outlook, Exchange, Manual. There was a period after that when Apple Mail would randomly ask for login details again, but otherwise it has worked fine. I'm guessing with my migration to and/or macOS updates on the new MacBook that setup got lost. And for sure when I deleted the Outlook account in an attempt to fix access.

With the new details, any better idea as to when this issue may be fixed?

I'm glad to report that at least for my situation, I have now been able to add my Outlook Email account to the Mail App under Sequoia on my new MacBook . It is currently in the process of downloading my Email. The Inbox is up to date with the Web based Outlook and Mail under Monterey on my older MacBook.

Based on Dave's comments I contacted Apple support and described my issue. They had no details about the issue, but did suggest I upgrade to the latest version of Sequoia.

I was running 15.6. So I thought it cannot hurt, so I updated to 15.7.1 after which I immediately tested adding Outlook to Mail. I selected the recommended choice of "Microsoft Exchange" as the provider. I gave my Email address and then clicked on the "SignIn" button like in the past. However, unlike in the past where there was a new window quickly overlayed with popups about failing verification, the window was from Microsoft and wanted info to verify my Email account!!! I filled in the Email address to send a code to, which showed up and I entered into the updated window. That worked and I got a new window asking what services of Outlook I wanted to use. I selected just Email like I had been using. At which point the new "Exchange" account was created in the Mail App. The settings are almost identical to what I had and is still on my old MacBook. Only difference I found is what to do about erasing deleted Emails; Never vs my previous after 1 month.

I just sent an Email from another account and it took awhile, but has now shown up in the Outlook account on all my machines!! I suspect my new MacBook Mail is sluggish since it is still downloading Email. Also the Outlook servers may be busy if other people are in the process of fixing their access to Outlook Email.

Hopefully you all will have the same luck I had it getting Outlook Email access back. I have no idea if my macOS upgrade fixed this or Apple and Microsoft did magical things in the background. Maybe Dave can learn some details from his contacts.

Good Luck and Good Night

I have Sequoia 15.7.1 and still facing the issue of being unable to add my outlook.com account.

Mansoor, I may have just been lucky. However, the fact that I was able to have it work makes me think something is happening at Apple and/or Microsoft to address this issue, it just may not been complete yet.

If you have not, I would suggest shutting down your machine and restart it. Then try to do the outlook add again. The reboot may help, but I'm mostly guessing here.

Hi @Grizzly55
Thank you very much for your detailed experience.

I have been on hold for a frew days as I did not know what could have happened as this issue is only happening for Apple Mail.

I tried to update to MacOS Sequoia latest version (15.7.1) and I could confirm that I could access to Apple Mail with personal Microsoft account and "Exchange" option.

For affected users, please try to upgrade to latest version of MacOS Sequoia to see if it could help.
The issue looks strange to me as for the past days, only Apple Mail did not allow me to sign-in with personal Microsoft account while Outlook and other third-party clients I have been testing worked normally so far.

Austin-H, The image you posted is what I saw when it worked for me, which is a good sign. However, it does not seem to be clear that 15.7.1 is the key. Since Mansoor is already there and he still had issues. Also Dave upgraded through Sequoia and then Tahoe, but still had issues.

If other people on this thread have been able to now add Outlook to Mail, please report that so we have a better picture of the status of this issue.

Thanks
