Question

Hello Sir,
Could some one help me on the below issue. As we are getting exchange alert from the SCOM Sever more frequently. No error id's in SCOM server as well as in exchange server. The OWA links are opening fine with out any issues for the external users, but still
getting alert from SCOM.
In SCOM Server the "CLIENT ACEESS" has RED X.(ERROR)
Please assist us how to fix the below error.

Hi,
This cmdlet runs against a Mailbox server by using a specific mailbox. Make sure that this mailbox has been created by running the new-TestCasConnectivityUser.ps1 script.
