Hi @Michael Eriksson ,
I did much research regarding "MaxEnvelopeSizeKb" but didn't see any statement about its maximum supported size. However, as regards to the error message you encountered above, to the best of my knowledge, in most cases it can be resolved by increasing the value of MaxEnvelopeSizeKb. I've seen in several links that the value was raised to 8000 or higher, so agree with Andy that it's suggested to have a go by setting it to a larger value like 8192 and check the result.
Here are some relevant links for your reference:
winrm set winrm/config @{MaxEnvelopeSizekb="8192"} :: Error - The IP Filter is invalid
Exchange 2013 in EMC you get he WinRM client sent a request to the remote WS-Management service and was notified that the request size exceeded the configured MaxEnvelopeSize quota.
