Hi,

I am having an issue with Exchange 2010 OWA. I have followed the article http://technet.microsoft.com/en-us/library/hh529949.aspx and a couple of others which all get you to change the owa web.config file to show

maxAllowedContentLength (set to 52430000)

and

maxRequestLength (set to 51200).

I have also run

appcmd set config "Default Web Site/owa" -section:requestFiltering -requestLimits.maxAllowedContentLength:51200000

and then done iisreset and restarted the Exchange topology service. Below are the current limits obtained from EMS

Get-TransportConfig | fl max*

MaxDumpsterSizePerDatabase : 36 MB (37,748,736 bytes)
MaxDumpsterTime            : 7.00:00:00

MaxRecipientEnvelopeLimit  : 500
MaxSendSize                : 2 GB (2,147,482,624 bytes)

and

Get-Mailbox -id administrator |fl max*size

MaxSendSize    : 50 MB (52,428,800 bytes)
MaxReceiveSize : 50 MB (52,428,800 bytes)

but I still can't attach a file in OWA above 5MB and receive the

error. Does anyone have any further ideas on this?
