Exchange Server 2007 and macbook large emails

For the life of me,
I can figure out why Macbook users are not able to send large emails but Windows machines have no issue.  Is there a special command line in either Exchange and or the macbooks themselves to get a higher max.  Ultimately, my goal is to set the max of my mac users to 20mb emails.  

As it stands right now, these specific MAC users are set up with unlimited send and receive in my exchange server  

In my GET-TRASPORTCONFIG , the max send and receive are set for 1002400kb
In my Connector limits, it is set for unlimited.

However, I do have one piece of info that might be preventing the large emails.....they are all wireless users.  Is there a way to change the setting in wireless routers to help larger emails to go through?

I have both Meraki and Cisco type routers
Thank you in advance for your help!!
Linda

Hey Linda,

This is a good question. Luckily enough I have an answer, but it is long :)

Mac clients typically utilize EWS (Exchange Web Services) depending on your version. Outlook for Mac 2011 and Entourage 2008, Web Services Edition uses EWS so there is a bit more complexity added here..

Because Mac's utilize EWS to perform syncs and mail delivery within Exchange, you have a particular overhead on your packets being sent mainly due to the EWS (asp.net module) conversion. You need to calculate the total amount you wish a Mac user to send (lets say 20MB file) + 40% overhead. This would equate out to 28mb total.

Now there are several things you need to think about changing..

- If your organizational limit on send / receive attachment sizes is going to be 20MB, you should increase this by 40% to accommodate Mac users if you can handle that type of traffic. You can find steps for changing that here, as it is essentially the same between Exchange 2007 and 2010: http://support.microsoft.com/kb/2222370

- The next portion is increasing the size of the attachments Mac users can send. Although this article is discussing how to increase this for Entourage users, this goes for Outlook for Mac also. You will need to edit the Web.Config file for EWS, so please make sure you have a valid backup of it: http://support.microsoft.com/kb/935848. I would recommend doing this after hours.

Sorry for blabbing so much. If you have any questions please feel free to drop a line :)

This fixed my issue!!  I was not able to fix this particular issue for the last 3 years--too busy to be able to focus enough attention.

Thank you so much!!
