Azure Migrate is a straightforward method to migrate VMware virtual machines to Azure. You just deploy an Azure Migrate Appliance on the on-premise data center. And then replicate VMware virtual machines to Azure. The Azure Migrate Appliance upgrades to the latest version in launching. You may see the connectivity check failed in the “Set up prerequisites” step after the updating.
The connectivity check to Azure is failing
If the connectivity check failed error is related to “https://www.office.com/login“. Then the reason is the undocumented URL. “*.office.com” should be whitelisted on the firewall. The URL is presented in prerequisites recently. In addition, Microsoft is not yet updating it in their document at this moment.
