Exchange 2007 SP1 Configured: Hub Server Can not receive messages with attachments over 10MB in size. Would like to increase that to at least 100MB. Is the only way to change this setting in using the powershell? If so, how? Not real familiar with the powershell. Any insight would be greatly appreciated.

Not that I would encourage you to NOT use the PowerShell (cause it is cool!), but look under the Organization properties for the Hub Transport. There should be a Global Settings tab. Look at the properties of the Transport Settings. There, you can set the global message size limits. However, if you are curious about using the PowerShell / Exchange Management Shell, here is what I did to view the config: [PS] C:\>Get-TransportConfig ClearCategories : TrueGenerateCopyOfDSNFor : {5.4.8, 5.4.6, 5.4.4, 5.2.4, 5.2.0, 5.1.4}InternalSMTPServers : {}JournalingReportNdrTo : <>MaxDumpsterSizePerStorageGroup : 18MBMaxDumpsterTime : 7.00:00:00MaxReceiveSize : 10MBMaxRecipientEnvelopeLimit : 1000MaxSendSize : 10MBTLSReceiveDomainSecureList : {}TLSSendDomainSecureList : {}VerifySecureSubmitEnabled : FalseVoicemailJournalingEnabled : TrueXexch50Enabled : True So, the properties you want to set are MaxReceiveSize and MaxSendSize, so you could type this at the EMS prompt: Set-TransportConfig -MaxReceiveSize 100MB -MaxSendSize 100MB

Ok. SOS. When I look under the Organization properties for the Hub Transport. There is no Global Settings tab.And of course I dont see properties of the Transport Settings.The tabs I dosee Under organization configuration ---> Hub Transport --> Remote domains, Accepted Domains, Email Address Policies, Transport Rules, Edge Subscriptions, Send connectors, Journaling. (so am i even in the right sport) Also when I try to use a command in the powershell. It let me know that the term is not recognized cmdlet, function, operable program, or script file. Verify the term and try again. Here is a sample of what I am typing: PS C:\Documents and Settings\Administrator> Get-TransportConfig Does the syntax look right? Oh this is terrible.

Sounds like you opened the regular PowerShell window instead of the Exchange Management Shell. Try openeing it instead and then run the Get-TranspoertConfig command.Also the you can look at the Receive Conectors under Server Config -> Hub Transport, each HUB server will have it's own Receive Connector. Thanks Will

Ok. I was in the Windows powershell and not the Exchange Management Shell(whew!). And once I realized that......I was able to set the size of theattachments. Thanks guys.
