I have recently migrated to Exchange 2010
I have increased my allowed file attachment size by changing :
TransportConfig MaxSendSize and MaxReceiveSize to 1Gb
and increasing the mailbox send and receive limits for various users.
This is fine when using Outlook. We can attach and send large files now.
My problem is with Outlook Web App.
Originally I was seeing this message when attaching a large(ish) file (in this case 30Mb) in OWA
I then increase my file size that OWA can handle as according to this article:
So I change:
<httpRuntime maxRequestLength="35000" />
<httpRuntime maxRequestLength="50000" />
Now when I try to attach a file in OWA I get this error:
I can't attach the 30 Mb file still. If I put the web config back to its original defaults and restart my OWA session I get back to the original error with the 25Mb stated. Any deviation from the original values shows message 2 (that doesn't state a file size).
Basically I am unable to modify this setting it seems.
Has anyone seen this before or have a solution to this ?
