The data connector for the Exchange Admin and Audit Log Events uses 'MS Exchange Management' as the log name when it should be 'MSExchange Management'. For example: Click Add Windows event log and enter MS Exchange Management as log name.
To reproduce the issue, install the Exchange On-Premises solution and try to configure:
[Option 1] MS Exchange Management Log collection > Data Collection Rules - When the legacy Azure Log Analytics Agent is used > Configure the logs to be collected.
And
[Option 1] MS Exchange Management Log collection > Data Collection Rules - When Azure Monitor Agent is used > Option 2 - Manual Deployment of Azure Automation.

An example of the event name (Which is used correctly in the parsers etc through the solution already):
