Receive Exchange Attachment size

Great article on all the spots to check:

http://eightwone.com/2010/09/29/exchange-message-size-limits/

Might have missed the transport settings:

Organization Configuration > Hub Transport > Global settings

Thank you very much... that is a perfect article!  I checked everything and i had missed the Organization hub transport. it is now also set.  

Still getting the bounce @ 10 Mb's however.  "This message wasn't delivered to anyone because it's too large. The limit is 10 MB. This message is 18 MB"

However when entering "Get-TransportConfig | Fl max*size" in the power shell  i get the correct response on the setting:  MaxReceiveSize : 20 MB's  

is this perhaps down to a reboot or is there a service that could be restarted?

Yes, a simple restart of the server would to.  If you are currently live and are unable to do so you could try restarting the exchange information store (for mailbox restirctions) and transport (for connectors).  I am trying to think of what else.

Don't bother restarting the server.
here is the complete list of all the places that need changing.  The first group gets the current sizes, the second will change the size limitations *EVERYWHERE* they need changing in order to make it work.

Get-SendConnector | fl MaxMessageSize 
Get-ReceiveConnector | fl MaxMessageSize
Get-TransportConfig | fl ExternalDsnMaxMessageAttachSize
Get-TransportConfig | fl InternalDsnMaxMessageAttachSize 
Get-TransportConfig | fl MaxSendSize
Get-TransportConfig | fl MaxReceiveSize

Get-SendConnector | Set-SendConnector –MaxMessageSize 20MB
Get-ReceiveConnector | Set-ReceiveConnector –MaxMessageSize 20MB
Set-TransportConfig -ExternalDsnMaxMessageAttachSize 20MB
Set-TransportConfig -InternalDsnMaxMessageAttachSize 20MB
Set-TransportConfig -MaxSendSize 20MB
Set-TransportConfig -MaxReceiveSize 20MB

Thanks jrhelgeson!  I appreciate it very much.

I made the changes but i skipped the send connectors as we do not want to open those up.

it is interesting that when sending a test i do not a bounce but i do not receive the emails either?  Using Gmail..  perhaps they will not send anything over 10?

Gmail I believe sends up to 25.  Could also be the ISP does not allow it.

Update .. doing more test today.  I have sent several however and not receiving a bounce but the email is not being delivered.

When looking at the Barracuda Spam filter the test (18MB's) email shows up there and indicates "delivered".  But the email is not showing up in the recipients outlook.

See if you can open up EMC and do a message tracking.  Exchange would have thrown an NDR (if turned on).  Check the junk folder if applicable.

Update ....  i am again receiving a bounce message.  possibility a reboot is in order?

Thanks !   I will make that change

jrhelgeson - It appears doubling it to 40 MB's did the trick!  I had no idea 2x the size would be necessary.

I appreciate everyone's help!
