Outlook 365 for Mac broken?

Problem reported by Eric Tykwinski - 1/2/2026 at 2:11 PM

Submitted

So, I had a customer call today about setting up their new iMac with Office. I usually suggest just using Apple Mail, but I can't tell customers which clients to use. I tried setting it up on my MacBook Pro here, and couldn't figure out what Microsoft wanted either.

New interface as for the following:

Email Address: user@domain.com

Full Name: (Optional)

DOMAIN\Username or email: user@domain.com

Password: ???

Server: https:// or http://

I tried mail.smartermail.com and mail.smartermail.com/EWS/Exchange.asmx but neither worked.

Obliviously, I'm using ficticious domain names and server names, but I can't get it to connect.

I don't think I see either attempt though hit the server under Administrative logs.

Anyone successful setting up a new version of Outlook 365 on Mac and any tips....

I suspect your customer is using Outlook New on their Mac.

How do they want to connect to SM? POP3, IMAP, or EWS?

Outlook New only supports POP3/SMTP without any problems.

Third-party IMAP always causes problems.

EWS is no longer supported in Outlook New and will be discontinued by Microsoft on October 1, 2026.

We have to accept that MS Outlook will only be usable with MS365 (Exchange Online) in the near future.

However, there are some pretty good alternatives, such as em Client.

As much as i would love to recommend an alternative, that just doesn't fly with most clients (at least around here)

My guess is that MS will milk this as long as possible until they start getting wind of anti-trust / monopoly investigations then miraculously an update will appear with at least MAPI (or something similar) to appease those launching the investigation.

In the mean time, they are banking on as many people as possible getting nervous and switching because of lack of current support.

gotta love the big guys eh ... that's why we tell our clients to use webmail lol

If anyone is interested, you can setup the account as an IMAP account, and then click Legacy Outlook to switch to the old UI, and it will setup fine as EWS with https://mail.smartermail.com/EWS/Exchange.asmx as the server.

P.S. It's not just SmarterMail that is broken, as I tried a legacy Exchange 2013 server and it no longer works on the new UI either.
