Exchange Online Connectivity Health Test

The Exchange Online Connectivity Health test allows you to determine network quality and identify issues that can affect network performance between your client computers and Exchange Online.

You can view the time (in milliseconds) a round trip takes from your computer to Exchange Online (Office 365). You can also view any warnings and errors for the different ports used to access Exchange Online services.

Exchange Online Mailbox Logon Health Test

The Exchange Online Mailbox Logon Health test verifies mailbox accessibility by logging on to Exchange Online. The test uses the Office 365 credential that you specified for either a hybrid Exchange Online connection or for a native Office 365 connection. The credential must have an associated Exchange Online mailbox.

When the logon process succeeds, the test displays Logon Succeeded. Logon latency shows the time that elapsed during the logon process (in seconds).

If you are using OAuth 2.0 to connect to Office 365, you must provide Application ID, Tenant ID, and Client Secret that were assigned when the UC Diagnostics application was registered with the Microsoft Azure portal. For more information, see Registering UC Diagnostics with the Microsoft Azure portal .

Exchange Online Message Delivery Health Test

The Exchange Online Message Delivery Health test monitors overall message delivery health for both hybrid and native Exchange Online, including test messages sent internally and externally.

•
Internal message delivery can be between Exchange on-premise mailboxes and Exchange Online mailboxes, or between mailboxes within Exchange Online. For hybrid environments, you could set either the source or target mailbox to be on-premise or Exchange Online. For native environments, both mailboxes would be Exchange Online.
•
External message delivery detects message delivery between Exchange Online and the internet. You must create an internal mailbox as source mailbox and an external mailbox as the destination mailbox. The source mailbox is an Exchange Online mailbox. The destination mailbox must be configured to send an auto-reply message.

The Exchange Online Message Delivery Health test uses Exchange Web Services (EWS) for internal and external message delivery tests.

If you are using OAuth 2.0 to connect to Office 365, you must provide Application ID, Tenant ID, and Client Secret that were assigned when the UC Diagnostics application was registered with the Microsoft Azure portal. For more information, see Registering UC Diagnostics with the Microsoft Azure portal .

The process to create an Exchange Online message delivery health test is as follows.

Office 365 Subscription Health Test

The Office 365 Subscription Health test provides an overview of your Office 365 licensing plans. Licensing plans define the Office 365 services that are available to users. The test shows license activity such as the number of licenses that are currently assigned to users (used) and how many licenses are due for renewal.

About the Office 365 subscription lifecycle

During the first 30 days after an Office 365 subscription ends, the Office 365 tenant account is in a period known as the expired state. During the expired period, users can still access data. After 30 days, the tenant account enters the disabled state for 90 days. During this period, users cannot access data. An Office 365 administrator can log in, backup data, or reactivate the subscription.

At the end of the disabled state, 120 days after the subscription has ended, the account enters the deprovisioning state. During the deprovisioning state, the data from user accounts and also email data and documents, is permanently deleted.
