Every time i try to send an attachment over 20 Mb, Outlook 2011 for mac gives me the following message: the message size exceeds the maximum limit set on the server.
Where do i change these limits?

You can increase message limits for individual protocols, see bellow:
Create Message Size Limits (50 MB
OWA Attachment Sizes: (Note: This must be completed on every CAS server)
Use Notepad to change the maxRequestLength value
1. Find the Outlook Web App Web.config file on the Client Access server. The default location is \Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa.
2. Make a backup copy of the web.config file.
3. Open the original file using an editor such as Notepad. Don’t use Internet Information Services (IIS) Manager to edit the Web.config file.
4. Find maxRequestLength and change it to the value that you want. The value is stored in kilobytes (KB). The default value is 35000. The following example shows the maxRequestLength value in the Web.config file.
Note: This is 50 MB (1024 X 50)
5. Save and close the file.
