Exchange 2007 Attachment Question
Hello Experts, I have a quick question that is probably really simple, but just need to verify something. I have an Edge/Exchange 07 setup, and if I change all the attachment size limits in the appropriate location (Let’s say to 10MB) and then I set a specific users attachment size to (Let’s say 15MB) the attachment is still getting rejected with an NDR. My question is does Exchange always take the lower number (Which would be the 10MB). The second part is if that is the case do I need to set all the attachment size limits to say 30MB and then set each specific user attachment size to say 10MB??

Well, not necessarily.. If you set a 10MB limit on the external connector (IMC), and then a 15MB limit on the user, then the user is never going to get the message because the IMC will drop it..
But, internal emails could be sent at that larger size..

Ok, so the lower setting does win??
To both "Jjdurrant" & "Exx1976" so what does that mean for my second question see above?

Jjmck, just to clarify what you said...In other words to answer my second question. I should set the message limits to say 30MB and then specify for each users mailbox what limit they are allowed to send/receive, etc...??

I would set the attachment size at the store level for all users.. make the size +20% of the number you want to restrict to allow overhead
So if you want to allow 10mb attachments, set to 12MB
So if you want to allow 10mb attachments, set to 12MB
If the maximum user limit you intend to set is 30MB, you should set a 30MB limit at the edge and hub level. If you want everyone to have a 30MB limit, there is no need to set a limit at the mailbox level.

You don't set mailbox limits at the store level in Exchange 2007. It is done on the hub transport and edge level. There is no need to set an "overhead". If you want to restrict everyone to 10MB, set the limit at 10MB.

Sorry, I thought he was running 2003.

Thanks everyone for there quick reply's.
One last thing.
The question got prompted because there is currently a 10MB limit set for everyone at the edge and hub levels. There is one user who may need to receive say a 12MB message. To make sure I got it..I really need to set it to say 15MB at the edge and hub level and then set all users at 10MB and then that particular user at 13MB??
I am also increasing the points because this question got more involved then I thought initially it would. :)

You could.. but why not just have it 15mb for all?

Jjdurrant, your right I could just make my life easier and make it 15MB across the board. However, you know those users that no matter how many times you tell them the limit is 10MB they always seem to forget?? Well most of those users finally got it through there head that the limit is 10MB. You also know those wonderful users who always want to test the system, you know the same ones that if you give a little, they like to tell the whole company hey look what I can do. The other big reason is bandwidth, but yes I do agree it would be much simpler on me to just make it 15MB for everyone. Thank you for all of your help.
JJmck, I think that is the route I am going to head for. Thank you for your help as well.

Remember that content conversion happens when Exchange converts an internet/MIME message into MAPI/Exchange format, and vice versa. Content conversion generally increases the message size – up to 30%. For example, if a maximum message size of 10MB, and you wonder why a 9MB attachment didn't make it through, consider the content conversion overhead, as also message headers (which are computed along with the DATA portion of the message to calculate the message size).
