Microsoft Outlook Outage: What Kansas City Landlords Should Know

On Thursday afternoon, the email system a huge number of businesses run on went quiet. Microsoft 365, the service behind Outlook email for business accounts, stopped working for a large share of its users, and Alpine Property Management was one of them. Here is what happened, how to reach us while it lasts, and what every rental owner should take from it.

What happened in the Microsoft outage on November 12, 2026?

Reports of trouble began on Downdetector around noon Eastern time on Thursday, which is 11 a.m. here in Kansas City, according to WKYT's report on the nationwide Outlook outage. By 2 p.m. Eastern, more than 97,000 reports had been filed. People could not get into Outlook on the web, on desktop computers or on their phones, and Microsoft Teams scheduling and messaging were disrupted as well.

Microsoft's status account said it was investigating reports of users having trouble accessing Exchange Online mailboxes through multiple connection methods in the Americas. Exchange Online is the server side of Outlook for business accounts, so when it stumbles, a company's email stops in both directions. As of Thursday afternoon, Microsoft had not given an estimated time for restoring service. TechRadar is also following Microsoft's response as it develops.

How can tenants and owners reach Alpine while email is down?

Pick up the phone. Our office line, 816.343.4520, runs on our own phone system, which is separate from Microsoft, and the outage has not affected it. You can call it or text it, and texts to that number reach our team directly. Every other way to reach us is listed on our contact page, but while email is down, the phone is the fastest route.

• Tenants with a maintenance emergency: call 816.343.4520 any time, day or night. Water where it should not be, no heat, a gas smell or a security problem should always be a phone call, outage or not.
• Tenants paying rent: rent payments go through the tenant portal, which runs on a separate platform from our email.
• Tenants with a routine repair: the tenant portal still takes requests. A quick call or text gets it in front of our team the same day.
• Owners: call or text the same number. Your owner portal and monthly statements live on that same separate platform, not in your inbox.
• Investors and new owners: if you were waiting on an email reply from us about management or a property, call 816.343.4520 and we will pick up where we left off.

Will emails sent during the outage be lost?

Probably not, but do not count on them arriving today. Email was designed to survive this kind of failure. When a receiving server cannot accept a message, the sending server is supposed to hold it and keep retrying. The internet standard that governs email delivery, RFC 5321, says a sender should generally keep trying for at least four to five days before giving up. In practice, most mail sent to an affected inbox during an outage shows up late rather than disappearing.

Most is not all. Some senders give up sooner, and some messages bounce back to the sender with an error. If you emailed us on Thursday about anything time sensitive, assume we have not read it yet and call. If you received a bounce message, your email did not reach us, so send it again once service is back or tell us by phone.

Why is email a weak link for rental property communication?

Rentals do not keep business hours, and the problems that matter most are the ones that cannot wait. A furnace that quits on a cold November night or a supply line that bursts under a sink needs a person on the other end within minutes. Email is built for things that can wait an hour or a day, which makes it the wrong channel for an emergency even on a normal day.

Thursday showed the other weakness. A landlord who runs everything through one inbox gets no warning when that inbox goes dark. Tenants keep writing, nothing comes back, and the first sign of trouble is an angry phone call or a repair that never got scheduled. For an out of state owner who relies on email to stay close to a property, an outage like this one can cut the line completely.

What should a landlord's backup plan look like when email goes down?

You do not need an elaborate system. You need more than one way in and out, set up before you need it.

• A phone number tenants already know. Put it in the lease, in the move in paperwork and in every email signature, so tenants reach for it without thinking.
• An emergency line that is answered day or night. A voicemail box that someone checks in the morning is not an emergency line.
• Texting on that same number. Many tenants would rather text than call, and a text gets through when an inbox does not.
• A tenant portal for rent and routine requests. Payments and work orders should live in a system that does not depend on your email.
• Vendor numbers you can dial. If your plumber and heating company only hear from you by email, an outage stalls every open repair.
• A public place to post an update. A short note on your Google Business Profile and social pages tells everyone at once where to go instead.

How does Alpine keep communication running during an outage?

We set up our communication so that no single company can take all of it down. Our phone system runs separately from Microsoft, so calls and texts to 816.343.4520 were not affected by Thursday's outage. Tenants who call after hours with a maintenance emergency are routed to our emergency maintenance service. Rent payments and owner statements live in our tenant and owner portals, on a separate platform. And the same afternoon the outage started, we posted a notice with our phone number to our Google Business Profile and every social channel we run, so tenants, owners and applicants knew where to go.

None of this was built for one bad Thursday. It is how we run every day, and it is the same discipline behind a 96% occupancy rate and a 98% rent collection rate. You can read more about how we handle maintenance requests and repairs, and about the winter tenant complaints we handle most.

What should owners ask a property manager about outages?

If you own rentals in Kansas City from another state, you are trusting your manager to stay reachable when things break, including their own systems. Before you hire anyone, or at your next check in with your current manager, ask these questions:

• What happens to tenant emergencies if your email or software goes down?
• Is your emergency line answered day or night, or does it go to voicemail?
• Can tenants text you, and does texting run on a separate system from email?
• Where do rent payments and work orders live, and do they depend on your email?
• How will you tell me and my tenants when one of your systems is down?

These belong next to the questions to ask before hiring a property manager as a remote investor. A manager who has thought through the answers has usually thought through a lot of other failure points too. To see what is included in our full management services, or to walk through your properties with us, talk with our team.

How will you know when Microsoft email is back?

Microsoft posts live updates on its Microsoft 365 service status page. Once our inboxes are working again, our team will work through everything that arrived during the outage. Until then, and for anything urgent at any time, call or text 816.343.4520.
