552 4.3.1 Message size exceeds fixed maximum message size

I have check the recipient message it is 5000, I am not able to send & received any attachment with 2mb file internal and external domains also.please suggest me..?

Try this
In system manager/Expand Administrative Group/Expand Server Group/expand your Server/First Storage/Expand First Storage Group/Mailbox Store--Properties check for limits and there you can change the limits for the send and recieve capacity...

Best of Luck
