Hi @Rafal Sawicz,

Thank you for reaching out to the Microsoft Q&A forum.

I truly understand you're having trouble signing in to your academic account on Microsoft Teams and Outlook, while your personal account works without any issues. I appreciate the steps you've already taken, including clearing the cache and reinstalling the apps.

Because your account is managed under your school’s domain, only your school’s IT department has the necessary permissions to help you check licenses with your account.

If you don't know who your IT administrator is, I recommend the following:

Ask your teacher.
Contact your institution's academic affairs office. They should be able to direct you to the right IT contact.

Moreover, some education licenses, such as Microsoft 365 A1 or A3, are designed primarily for web access and may have limitations when used with desktop or mobile apps.

For your reference: Compare Microsoft 365 Education Plans | Microsoft Education

To ensure full access, you can ask your school’s IT administrator to check your license type in the Microsoft 365 Admin Center by following the step below:

Go to the Microsoft 365 Admin Center
Navigate to Users > Active Users
Search for your name or university email address
Click on your profile, then go to Licenses and Apps
Check if the Office 365 A1 or A3 licenses is selected
Under “Apps,” make sure the checkbox for Office desktop apps is enabled
Save any changes if needed

Once the A1 or A3 license is assigned and the desktop apps are enabled, you’ll be able to download and activate the full Office suite without any additional cost.

Hi, thanks for the reply. I forgot to mention that I don't have any issues with logging in on windows desktop app and mobile app on my android phone, it's only on my tablet with different OS (HarmonyOS).

And in "my account" tab there's information that I have Office 365 A3 license.

Hi @Rafal Sawicz,

Thank you for your message and for sharing the additional information. I truly appreciate your time and the clarity you've provided.

As of now, Microsoft Office apps such as Teams, Outlook, and others are not officially optimized for HarmonyOS, including the latest HarmonyOS Next. While some users have managed to use these apps through sideloading or web browsers, there have been reports of limited functionality and compatibility challenges.

Additionally, Microsoft does offer the Teams app through Huawei’s AppGallery. However, the sign-in process may be affected due to the absence of Google Mobile Services (GMS), which are typically used for authentication. This can lead to issues such as sign-in loops or getting stuck during verification, especially on devices that do not support Conditional Access policies or lack standard authentication services.

Moreover, Microsoft has not announced any plans to natively support HarmonyOS. The adaptation of these apps would depend on Microsoft's strategic decisions and market demand. Users are encouraged to provide feedback through Microsoft's official channels to express their need for HarmonyOS support.

As a forum moderator, I hope you understand that I don’t have the ability to modify or escalate product issues directly. However, I strongly recommend submitting your feedback through the Microsoft Teams · Community portal. This is the most effective way to ensure your voice reaches the product team and can be considered for future improvements.

You've clearly identified a real-world challenge, and your suggestion reflects a deep understanding of user needs - feedback like yours is truly valuable and helps shape the future of Microsoft Teams.

Sharing your experience through this channel is one of the most effective ways to advocate for improvements that benefit both you and the broader community. Once you’ve submitted your feedback, feel free to share the link here. I’d be happy to upvote it to help increase its visibility.

If you're facing issues, you can try accessing these services via a web browser or explore alternative apps that are compatible with HarmonyOS. Let me know if you'd like help with troubleshooting or finding alternatives!

Your understanding and co-operation are highly appreciated. Thanks for your precious time. Have a nice day.

Web version is working without any issues and logging in into the mobile app using my google account works too, but when I try to log in using my email in university's domain, then instead of redirecting me to university login page it shows an error 2604 both on WI-Fi and hotspot from my phone.

Hi @Rafal Sawicz,

Thank you for your response.

We truly understand that using your Google account and the web version to log in is successful, and that the problem only arises when you try to use your university email on your HarmonyOS tablet. Both Wi-Fi and mobile hotspot connections are displaying error 2604 instead of taking you to the login page for your university.

The way authentication functions on HarmonyOS devices is connected to this behavior. Although Huawei's AppGallery offers Microsoft Office apps like Teams and Outlook, HarmonyOS lacks Google Mobile Services (GMS), which is frequently used to facilitate secure sign-in processes. Because of this, certain devices might not be able to completely support the redirection procedure needed for institutional accounts, particularly those that are subject to Conditional Access restrictions.

Since Error 2604 typically appears when Microsoft 365 apps encounter a problem during the sign-in process. Although the message often suggests a network issue, it can also be triggered by:

Authentication flow interruptions, especially on devices without Google Mobile Services (GMS), like HarmonyOS tablets.

TLS protocol settings, which are essential for secure communication.

Conditional Access policies enforced by your university’s IT department.

Cached credentials or app configuration conflicts.

This error has been reported across various platforms including iOS, macOS, and HarmonyOS, especially when logging in with institutional accounts.

We truly appreciate your patience and understanding as you work through this. If you have any questions or need further assistance, please feel free to reach out. We're here to help.

Hi, thanks for your time, but none of your suggestions helped resolve this issue, I fully understand that Microsoft simply doesn't support HarmonyOS.

Hi @Rafal Sawicz,

Thank you so much for your thoughtful follow-up. I truly appreciate the time you’ve taken to explore the suggestions and your understanding of the current limitations regarding HarmonyOS support.

While HarmonyOS isn’t officially supported by Microsoft at this time, I’m grateful for your openness and clarity. If there are any other questions or areas where I can assist whether related to Microsoft 365 or something else. I’d be more than happy to help.

Wishing you a great day ahead.
