Troubleshooting for Manual Setup

Error Description
See all licenses


You need your AccountSku number to be able to add users.
Add users

New-MsolUser -UserPrincipalName -ImmutableId -FirstName -LastName -DisplayName -LicenseAssignment -usageLocation

The immutable id is a unique user identifier on Office 365. Make sure Immutable id is reflected in the user's info on LastPass portal, as the user's ID. The user principal name is the IDPEmail. Both these values must match with the Office 365 configuration for single sign-on to be successful.
Delete users

emove-MsolUser -UserPrincipalName <User's email>

The above command moves the user to the Office 365 recycle bin. To create a user with the same name, make sure to remove the user from the recycle bin.
Retrieve a deleted user Get-MsolUser -ReturnDeletedUsers -SearchString <User's email> | select UserPrincipalName, ObjectId
Remove a deleted user from the recycle bin Remove-MsolUser -RemoveFromRecycleBin –ObjectId
Login error Some users might experience the following sign-in issue, due to a known bug on Office 365:

"Sorry, but we're having trouble signing you in. Please try again in a few minutes. If this doesn't work, you might want to contact your admin and report the following error: <error#>."

The solution is simply to restart your browser. Then open a fresh browser tab and try to log in.

Alternatively, LastPass MFA can be used for secure login to Office 365/Azure AD SSO while maintaining Azure AD as the primary Identity Provider. For more info, visit LastPass conditional access setup page.
