- Service Account Configuration:
- A service account in Office 365 with the "Global Administrator" role assigned. Verify this at the Microsoft Admin Center.
- MFA disabled for the service account to ensure uninterrupted integration.
- Permissions and Roles:
- The service account must have the "Application Impersonation" role assigned via the Exchange Admin Center.
- Appropriate permissions to access user mailboxes for synchronization and management.
- PowerShell and Modules:
- PowerShell version 7.2 or newer installed on the server.
- Exchange Online Management Module version 3.1.0 or higher installed. Install using:
Install-Module -Name ExchangeOnlineManagement -RequiredVersion 3.1.0 -Force
- Network Configuration:
- https://outlook.office365.com (HTTPS/443)
- Any additional MaaS360-specific endpoints.
- Ensure DNS is correctly configured, resolving outlook.office365.com.
- Allow outbound connections to the following URLs and ports:
- Administrative Access:
- Access to the IBM MaaS360 portal with appropriate administrative privileges to manage the Cloud Extender setup.
Procedure
Step 1: Verify the Service Account
- Log in to the Microsoft Admin Center.
- Navigate to Users > Active Users.
- Locate the service account and verify that it has the "Global Administrator" role assigned:
- If not assigned, click Manage roles, select Global Administrator, and save the changes.
Step 2: Disable Multi-Factor Authentication (MFA)
- In the Microsoft Admin Center, go to Users > Active Users.
- Select the service account and navigate to Authentication methods.
- Confirm that MFA is disabled for this account:
- If MFA is enabled, go to Security > Conditional Access.
- Edit Conditional Access policies to exclude the service account from MFA requirements.
Step 3: Assign Permissions in Exchange Admin Center
- Open the Exchange Admin Center.
- Go to Roles > Admin Roles.
Option 1: Add the Service Account to an Existing Organizational Group
- Locate an existing group such as "Organization Management" or another admin group with full permissions.
- Click Edit, add the service account (e.g., shrutibl@208vl3.onmicrosoft.com) as a member, and save the changes.
Option 2: Assign the ApplicationImpersonation Role Manually
- Open PowerShell as an Administrator.
- Run the following commands:
# Step 1: Install the Exchange Online Module
Install-Module -Name ExchangeOnlineManagement
# Step 2: Enable TLS 1.2 for Secure Connections
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
# Step 3: Connect to Exchange Online
Connect-ExchangeOnline -UserPrincipalName <admin-email>
# Step 4: Assign the ApplicationImpersonation Role
New-ManagementRoleAssignment -Name "ImpersonationRoleForShrutibl" -Role ApplicationImpersonation -User shrutibl@208vl3.onmicrosoft.com
# Step 5: Verify the Role Assignment
Get-ManagementRoleAssignment -Role "ApplicationImpersonation" | Where-Object {$_.RoleAssigneeName -eq "shrutibl@208vl3.onmicrosoft.com"}
Option 3: Enable Organization Customization
- If the "Enable-OrganizationCustomization" command is required:
Enable-OrganizationCustomization
Get-OrganizationConfig | Format-List IsDehydrated
- Wait for the process to complete and retry the steps above.
Save changes after completing either method and proceed to validate the configuration.
Step 4: Install PowerShell and Exchange Online Management Module
- Open PowerShell as an administrator.
- Install the required version of the Exchange Online Management Module:
Install-Module -Name ExchangeOnlineManagement -RequiredVersion 3.1.0 -Force
- Update the PowerShell execution policy:
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
Step 5: Connect to Exchange Online
- Use PowerShell to connect the service account to Exchange Online:
2. $Credentials = Get-Credential
Connect-ExchangeOnline -Credential $Credentials
- Test the connection by listing mailboxes:
Get-Mailbox
Step 6: Configure the Cloud Extender
- Open the Cloud Extender Configuration Tool on your server.
- Select Exchange ActiveSync Module and click Start.
- Provide the following details:
- Email Server Hostname: outlook.office365.com
- Username: Full service account email address.
- Password: Service account password.
- Domain: <tenant>.onmicrosoft.com
- Validate the configuration by clicking Validate All Accounts.
Challenges and Troubleshooting
- Exchange Online Management Module Version Requirement:
- Ensure the Exchange Online Management Module version is 3.1.0 or higher. This is mandatory for integration to function correctly.
- Invalid Credentials Due to Exchange Online Management Module or Registry Settings:
Error: "Unable to authenticate the following service account."
- Cause: The Exchange Online Management Module version is not 3.1.0 or higher, or the necessary registry settings for TLS and strong cryptography are missing.
Solution:
- Ensure the Exchange Online Management Module version is 3.1.0 or higher by running:
Install-Module -Name ExchangeOnlineManagement -RequiredVersion 3.1.0 -Force
- Update the registry with the following keys for secure communication:
o [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727]
o "SystemDefaultTlsVersions"=dword:00000001
o "SchUseStrongCrypto"=dword:00000001
o [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
o "SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001
- Reboot the system and retry the configuration.
- DNS and Network Errors:
- Use tools like nslookup and ping to verify network connectivity to outlook.office365.com.
- Confirm firewall settings allow access to required endpoints.
- Module Compatibility Issues:
- Ensure PowerShell version is 7.2 or newer.
- Reinstall the Exchange Online Management Module if issues persist.
- Check Exchange Online Permissions:
- Use PowerShell to verify that the service account has the "Application Impersonation" role:
Get-ManagementRoleAssignment -Role ApplicationImpersonation
- Validate Service Account Configuration:
- Log in to the Microsoft Admin Center to confirm that the service account is active and has the correct roles.
- Debug Cloud Extender Issues:
