The maximum number of concurrent shells for this user in Lync Online has been exceeded
Topic Last Modified: 2013-07-05
Each administrator is allowed a maximum of three simultaneous remote connections to Lync Online. If you have three remote Windows PowerShell connections up and running, any attempt to make a fourth simultaneous connection will fail, with the following error message:
New-PSSession : [admin.vdomain.com] Connecting to remote server admin.vdomain.com failed with the following error message : The WS-Management service cannot process the request. The maximum number of concurrent shells for this user has been exceeded. Close existing shells or raise the quota for this user. For more information, see the about_Remote_Troubleshooting Help topic.
The only way to resolve this issue is to close one or more of the previous connections. When you are finished with a Lync Online session, we recommend that you use the Remove-PSSession cmdlet to terminate the session. This will help you to prevent this issue.
