Hi,Im trying to set the maxsendsize and maxreceivesize limits for our exchange 2007 server and im getting some strange results.if you do the command get-transportconfig it displays the maxsendsize and maxreceivesize in KB. So one would assume that if i wanted to set a max send size of 5MB i would have to enter the following command: set-transportconfig -maxsendsize 5000. Right?however this does not work, the above command will display a max send size of 5KB. So to get a max send size of 5MB you have to enter in set-transportconfig -maxsendsize 5000000why does it display the results in KB when you have to enter the command in bytes. To me this is a silly design flaw. Does anyone else have this issue?

Hi, If you want a maxsendsize of 5Mb you would enter set-transportconfig -maxsendsize 5Mb Leif

Hi Rakem, If you are setting the MaxSendSize smaller than the default 10MB limit you will not have much of a problem if you follow the format Leif mentioned. If however you want to change the limit higher than this default value there are a fair few other places to change. They are defined in the following article: http://technet.microsoft.com/en-us/library/bb124345.aspx I had found that in my current migration from Domino to Exchange 2007 even though I had used the set-transportconfig and also change all the MaxSendSize values on all of the connectors, I was still unable to increase the maximum message size. When running the checks the users would be displayed as "Unlimited". I found that I had to perform the ADSIEDIT change to increase the Global limit discussed in this article : http://technet.microsoft.com/en-us/library/bb310771.aspx I beleive the Unlimited setting that the Command shell reports is actually Unlimited up to the Global Limit. From the Microsoft documentation I have read,this Global Limit should only bein effectwhen in a mixed Exchange 2003/2007 environment. This was not the case in the new Exchange 2007 Organisation I had setup. Cheers, Rhys
