Below are some clips we've found from Microsoft 365's phone menus and tips that help give an idea of what you will encounter when you call. We've highlighted why they are important as well:

Heard when the phone system first answers

"Hi. Thanks for calling Microsoft. Help us to improve the quality of our products, services, and training, this call may be recorded or monitored. And information collected on this call may be transferred to other countries."

They may ask your reason for calling (instead of a menu)

"Hi. Thanks for calling Microsoft.
To help us to improve the quality of our products, services, and training, this call may be recorded or monitored, and information collected on this call may be transferred to other countries.
To help me best assist you, I need to know if you are calling as a home user or as a business user."

What are the hours and when should I call?

Microsoft 365 operates the call center for this 800-865-9408 phone number 24 hours, 7 days. The short answer is that you should call on a Wednesday. This observation and the following section are based on analysis of a sample set of 155 calls made in the last 90 days using our free, web-based phone (see above).

Automatically call when they open

When you use our free AI-powered phone to call and talk, wait on hold, or navigate for you, it will automatically wait until the Microsoft 365 call center opens before trying to call. It will ask your permission before it places the call, so you can also further delay that scheduled call until you are ready. But that means you can "set it and forget it" ahead of time.

An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this Microsoft 365 phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like Microsoft 365 staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.

The least busy time to call

The least busy day to call Microsoft 365 is Wednesday. The most busy day to call is Tuesday, which averages 264% more phone calls by comparison. Again, this is based on a sample of 155 calls made with our AI-powered, web-based phone in the last 90 days.

The shortest wait on hold

We measured the shortest hold times to be on Friday. The longest wait in the queue on average occurs on Thursday.
But if you use our free call and talk for me or wait on hold for me service, you don't really need to worry about average wait times.

The best time to call Microsoft 365

In summation, the best day to call Microsoft 365 is Wednesday. This is not the day with the shortest wait on hold in the phone system, but we still recommend it for its ideal combination of low call volume and short hold times. Plus we believe that Microsoft 365 staffs the call center well on Wednesday.

Calling this Microsoft 365 Customer Number

There could be several reasons why a Microsoft Office 365 home or business user might call 800-865-9408 for support. Office 365 contains several software programs, each with unique challenges that can vex users. Additionally, those using Microsoft Office can access Microsoft One Drive cloud storage. One Drive can be challenging, so users might need support from Microsoft.

When you call the Microsoft 800-865-9408 number, like most software support lines, you're greeted with an automated message. The system directs you to press two for "Espanol,” and informs you that the call may be recorded, monitored and shared with other countries. Next, the system asks if the caller is a home or business user. Once you answer this question, the system prompts you to state why you are calling.

I told the system my call was about One Drive, Microsoft's cloud storage program. Unfortunately, the automated system didn't answer my question but directed me to help.microsoft.com for assistance. The automated assistant asked if I wanted to hear the information again. Then the call ended with, "Thanks for calling Microsoft. Have a good day." The system doesn't give an alternate number to call or offer a call-back option.

It seems the only way to get help is through the website. However, if you have had a previous encounter with customer service, you may already have a case number that could be the ticket to speaking with a human. 

What I found interesting is that as a home user, when I tried to call the number again from the same landline, the automated system directed me to the website and ended the call with "goodbye," which suggests that the system may have remembered that I had already called.

I called from my cell number, and after identifying as a business user, the automated system voice said, "I look forward to assisting you," and suggested they would get me help. However, as a business user, I needed a phone number associated with the product to get phone support. The system directed me to a "profile" website and said it may take up to 48 hours to get assistance.

Whether you're a home or business user, without a case number, you get a web address to visit for assistance. The system ends the call with no further help, such as alternate numbers or an offer to call the customer back.

Based on my experience with Office 365 Support's 800-865-9408 phone number, it only refers a caller to a website address. It offers no opportunities to interact with a human who might answer a question or walk the caller through a software issue.

If you're a home or business user with a problem that requires an immediate solution, know the case number and/or phone number associated with your account and be prepared to visit the website for help first.

As a last, sometimes only, resort- Microsoft 365 customer service can be accessed through their website. This can entail digging through help articles before finding a form and "being allowed" to submit a problem to their team, and rarely leads to a real-time conversation, which is why GetHuman does not recommend this unless it's the only way.
