Nov 22, 2023Exchange command and MaxEnvelopeSizekb
Hey all,
Trying to run a powershell command on Exchange 2019 mailbox server (on Server 2022) using the Exchange Management Shell and getting the below error:
Get-Mailbox | Get-MailboxStatistics | select DisplayName,{$_.TotalItemSize.Value.ToMB()},Database | export-csv "C:\tools\mailbox_size.csv"
Sending data to a remote command failed with the following error message: The WinRM client sent a request to the remote WS-Management service and was notified that the request size exceeded the configured MaxEnvelopeSize quota. For
more information, see the about_Remote_Troubleshooting Help topic.
+ CategoryInfo : OperationStopped: (ex01.pac.internal:String) [], PSRemotingTransportException
+ FullyQualifiedErrorId : JobFailure
I had already increased the size of MaxEnvelopeSizekb to 8192 but still get this error. Is it safe to increase the value even further?
thanks

Hi Deleted,
the error message you're encountering is related to the maximum data size that Windows Remote Management (WinRM) can handle in a single response. You've already increased the MaxEnvelopeSizekb value to 8192, which is a common solution for this issue.
If the problem persists, consider raising the MaxEnvelopeSizekb value even further.
Before proceeding, verify the current MaxEnvelopeSizekb value with the following command:
Get-Item -Path WSMan:\\localhost\\MaxEnvelopeSizekb
It is important to note that increasing this value should be done cautiously, as it affects the security and performance of your system. Here are a few considerations:
Security Implications: Increasing the MaxEnvelopeSizekb allows larger amounts of data to be sent over the network. While this might be necessary for certain operations, it also increases the potential impact of malicious or unintentional large data transfers. Ensure that you understand and accept the security implications of allowing larger envelope sizes.
Network Performance: Larger envelope sizes can lead to increased network traffic. Make sure that your network infrastructure can handle the increased load without significant degradation in performance.
Resource Usage: Larger data transfers require more resources on both the client and server sides. Ensure that your systems have sufficient resources (CPU, memory) to handle larger requests.
Application-specific Considerations: Some applications, including Exchange, may have their own limitations or recommendations regarding the maximum envelope size. Check the documentation for Exchange 2019 to see if there are any specific guidelines or recommendations.
