Office 365 Provisioning "Subscription" task fails with:
The 'Unlimited' values of limits for Office 365 Resource Types in Service Templates are not allowed. Such values are not supported by Office 365. You must update limits for 'Office 365' Service Templates and existing 'Office 365' subscriptions
The issue is caused by incorrect limits of the Office 365 license resources specified in service template or subscription.
Configure Office 365 service templates according to Office 365 Provider's Guide. Change limits for the subscription accordingly and restart the failed tasks.
