Attachment size setting inside Exchange server 2010 for global user settings.

  • Go to your mailbox server.
  • Open EMC.
  • Go to Organization Configuration.
  • Go to Hub Transport.
  • Click the Global Settings tab.

Edit the Transport settings and change the parameters as below.

Once you done it, click Apply and OK.

Remember one thing; the more you increase the size of the attachment, the load on the CAS & Edge server increase...plus the Virus scanning engine too.

Thats all folks!!!
