Exceeded Concurrent Shells Limit

Symptom:

An error that resembles the following message occurs when I have sent a request to the connector that involves contacting the endpoint:

[…This user is allowed a maximum number of 3 concurrent shells, which has been exceeded …]

Solution:

Exchange Online server has a limit of three sessions per user per machine. For better performance, the connector is expecting to have access to all the three available sessions. The error might be due to one of the following reasons:

• An active session has been created manually on the same machine using the same administrator credential.
• A session created by the connector is not cleaned-up.

To resolve this issue, perform one of the following actions below:

• Close the active session which are created manually.
• Manually ending all running PowerShell processes that are started by the connector.
• Restart the CA IAM Connector Server.
• Override the maxActive property in connector.xml to reflect the number of sessions available for the connector to use.
