Common Cause #1: Password Not Synced Between Active Directory and Azure
Why This Happens
In some cases, a user updates their Active Directory (AD) password, but the change does not successfully sync to Microsoft Azure. When this occurs, Microsoft Entra will reject the login attempt—even if the user is entering their correct, newly updated AD password.
How to Quickly Test This
To determine whether this is a password synchronization issue:
Try logging in to:
Use your current Active Directory password.
If the login fails on these Microsoft portals as well, it strongly indicates that your password has not synced to Azure.
What to Do Next
If your password does not work on the Microsoft portals:
Contact your IT department
Ask them to verify that password synchronization between Active Directory and Microsoft Azure is working correctly
Common Cause #2: Email Address Does Not Match Azure Username
Why This Happens
Microsoft Entra requires that the email address used to invite a user to the Resource Planning application exactly matches the user’s Azure username (User Principal Name).
In some organizations, a user’s login username may differ from their primary email address. For example:
Azure username:
john.doe@company.onmicrosoft.comEmail address used for the invite:
john.doe@company.com
Even though both may belong to the same user, Microsoft Entra treats them as different identities, which results in a login failure.
How to Check This
Confirm the exact username you use to sign in to Microsoft 365 or Azure
Compare it to the email address that received the Resource Planning invitation
They must be an exact match (including domain and spelling)
What to Do Next
If the email addresses do not match:
Contact your administrator or Resource Planning support
Request that the invitation be resent using the exact Azure username
Alternatively, your IT team can update the Azure user to align with the invited email address
