Hello, I use exchange 2007 and here my configuration regarding message size restrictions: 1) Global / Organizational Limits: MaxReceiveSize : 15240KB MaxSendSize : 15240KB 2. Connectors Limit MaxMessageSize : 20MB 3) ReceiveConnector MaxMessageSize : 10MB 4) Active Directory SiteLink Limit MaxMessageSize : unlimited MY QUESTIONS: 1) I would like all users to have their Maximum Sending/Receiving message size set to 15Mo. --> Would you know any shell command to set bot value at 30 Mo for all the mailbox users? 2) I also have a bunch of VIPs and I would need them to have their Maximum Sending/Receiving message size set to 30Mo. --> How could I set that value from a list of identity? (Get-content C:\vip.txt ???) 3) Last thing what message size restrictions should be cahnge in my organization? Shall I set Organizational Limits, Connectors Limit and ReceiveConnector to 35 Mo ? Many many thinks in advance. Graig

1)If you want all users to have 15M message size, I think you just need to configure the Global Limits to 15240KB as you set, but this size only works for the internal message. 2) You can set all the VIPs' mailbox limits to 30M with the powershell like: $vips=get-content c:\vip.txt foreach($vip in $vips) { SET-Mailbox –Identity $vip –MaxSendSize 31457280 -MaxReceiveSize 31457280 } 3) I think you can set the Global limits to 15M, then set some individual VIPs' limits to 30M, then if you want to the VIPs to send or receive 30M message outside, then you need to set the send/receive connector to 30M. But if we think about the Exchange server, I suggest you set the same size for global and connector limits.

Hello, Just to summarize: 1) Global / Organizational Limits: MaxReceiveSize : 30480KB MaxSendSize : 30480KB 2. Connectors Limit MaxMessageSize : 30MB 3) ReceiveConnector MaxMessageSize : 30MB 4) Active Directory SiteLink Limit MaxMessageSize : unlimited --> And finaly I guess that the below command will set 15 Mb for all users: Set-Mailbox -MaxSendSize 15MB -MaxReceiveSize 15MB Am I correct? Then I can set the VIPs as Nile adviced me to! Last thing should I set the SiteLink to 30 Mo too? Many thanks to all! you really highlighted me :-D
