Exchange Online issues

Issue: Exchange Online backup failing for users 

Exchange Online backups failing for users after 10 days of account configuration. When backups fail, the administrator receives an email with the subject "Cloud App status alert" with the following message:

Microsoft 365 is not connected. Please re-configure Microsoft 365.

While creating an account for global administrators on Microsoft 365, the StsRefreshTokensValidFrom attribute was not set by the APIs of the third party SSO tool.

Workaround

  1. Install the Azure module using the link:
    1. Download the Microsoft Online Services Sign-In Assistant for IT Professionals RTW from the Microsoft Download Center and then install it.
    2. Download the Azure Active Directory Module for Windows PowerShell (64-bit version) installer package and then click Run to run it.
  2. Connect to Azure AD:
    Run the cmdlet connect-msolservice command on the Windows PowerShell command prompt. You will then be prompted for your credentials. Enter your Azure AD (Global admin) credentials.
  3. Get StsRefreshTokensValidFrom attribute value of the global admin using the following command:
    $user = Get-MsolUser -UserPrincipalName ernie.carter@druva.com
    $user.StsRefreshTokensValidFrom

    where Ernie Carter is the global admin who is configuring the Microsoft 365 app
  4. The following command will set the current time as the value of the StsRefreshTokensValidFrom attribute for the global admin. Steps to set this value:
    $dt = Get-Date
    Set-MsolUser -UserPrincipalName ernie.carter@druva.com -StsRefreshTokensValidFrom 
    $dt.ToUniversalTime()
  5. Run step 3 again. This time you should see the current time (set in step 4). This is a verification step. 
  6. Re-configure inSync with Microsoft 365 using the steps mentioned in the Configure inSync with Microsoft 365 topic.

Resolution

Ensure that the User is logged in to Windows and Outlook at the time of backup. In addition, check if the inSyncUSyncer.exe process is running on the same user who is logged into the machine and has activated inSync Client.

The error can also occur if Outlook was not open on the machine when the backup was running.

This information is applicable to all the supported client OS.
