Fix University Microsoft 365 Password Changing Every 24 Hours
Question details
The user's university Microsoft 365 account password stops working approximately 24 hours after being reset by the IT department.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to stay signed into a university email and Microsoft 365 account across multiple devices (phones and laptops).
- Observed behavior
- The user is automatically logged out after about a day, and the password is rejected as incorrect despite repeated resets by the university IT team.
Ensure you have an alternative way to contact your university IT help desk, as resolving this persistent server-side identity issue requires their administrative access.
Request a Microsoft 365 Admin Escalation via University IT
Because the password rejection occurs across multiple devices, this is a server-side identity issue that your IT department must escalate to Microsoft.
When an account password repeatedly stops working exactly 24 hours after a reset, it typically indicates a synchronization error between the university's local Active Directory and Microsoft Entra ID (formerly Azure AD). It cannot be fixed on the user's end.
Write down the exact time your password was reset and the exact time you were logged out and rejected the following day. This helps administrators pinpoint the failing sync cycle.
Reach out to your IT help desk and inform them that the issue persists across all devices after multiple resets, indicating a server-side sync or token expiration issue.
Ask the IT administrator to create a formal service request within the Microsoft 365 admin center so that Microsoft engineers can investigate the repeated password change logs directly.
Clear Saved Device Credentials
Remove old cached passwords from your devices to ensure a corrupted login token isn't triggering a security lockout.
Locked out of your university account? Keep working with WPS Office
While waiting for your university IT team to resolve your Microsoft 365 password issues, you can continue working on your assignments using WPS Office. It is a completely free, highly compatible suite that lets you create and edit documents locally without requiring a restrictive institutional login.
- 1. Download and install: Get the free WPS Office installer from the official website and complete the quick installation process on your computer.
- 2. Open your assignments: Launch WPS Office and open your existing Microsoft Word, Excel, or PowerPoint files directly without needing to sign into a university account.
- 3. Save in standard formats: Edit your work and save it as standard Microsoft Office formats so you can easily submit it once your university account access is restored.
Frequently Asked Questions
Why does my Microsoft 365 password expire every 24 hours?
This is generally caused by an Active Directory synchronization error on the university's servers, or an aggressive automated security policy that misidentifies your login as a risk and forces a password rotation.
Can I fix a university account password loop myself?
No. If the password is being rejected across all devices (phones and laptops) after an IT reset, it is a server-level identity issue. It requires an IT administrator to fix it via the Microsoft 365 Admin Center.
Will clearing my browser cache stop the 24-hour logout?
If the issue happens simultaneously on multiple devices, clearing your cache will not fix it. The password rejection is occurring on Microsoft's servers, not locally in your browser.
