I thought it translated to "File Server". -----Original Message----- From: Fred Sawyer [mailto:fsaw...@victuscapitalconsulting.com] Sent: Wednesday, July 18, 2012 1:45 PM To: MS-Exchange Admin Issues Subject: RE: Increasing Attachment size for OWA and EWS?
Don - I so agree.. Sadly I must hang my head in shame and suck up the executive order. Most of these large attachments are internal only emails. Didn't you know email is Latin for "FTP"? -----Original Message----- From: Don Andrews [mailto:don.andr...@safeway.com] Sent: Wednesday, July 18, 2012 12:38 PM To: MS-Exchange Admin Issues Subject: RE: Increasing Attachment size for OWA and EWS? HOLY FTP Batman! Just curious what percentage of your clients/customers/vendors etc. allow that large a message size much less attachment size? -----Original Message----- From: Fred Sawyer [mailto:fsaw...@victuscapitalconsulting.com] Sent: Wednesday, July 18, 2012 10:36 AM To: MS-Exchange Admin Issues Subject: Increasing Attachment size for OWA and EWS? We are currently running on Exchange 2010 SP2 RU1 and I have been working on setting the accepted attachment size to 175MB. The proper values have been set on TransportConfig, ReceiveConnector's, SendConnector's, and user Message Size Restrictions. Outlook clients connecting with MAPI are able to send larger size attachements. My problem is Mac Mail clients that connect via EWS and OWA. I followed the following instructions for increasing attachment size in EWS and OWA. (I did changed the various values to be 175MB in the specified unit for the setting) 1. Increase the Global Transport configs for both MaxReceiveSize and MaxSendSize. This can be done through either the EMC GUI, or powershell (set-transportconfig) 2. Modify the /EWS web.config , <system.web> <httpruntime maxRequestLength="50000"> *this value is represented in kb* 3. Add new value to the the IIS7 applicationhost.config , underneath <system.webserver><security><requestfiltering>, add a new line named as follows : <RequestLimits maxAllowedContentLength= "50000000" /> *this value is represented in bytes* 4. Modify the /EWS web.config, <httpsTransport maxReceivedMessageSize="50000000" *this value is represented in bytes*authenticationScheme="Anonymous".....> 5. Restart IIS. And detailed description on how to increase the size to 50 MB: 1. Edit C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\web.config and update the maxRequestLength value to 51200 2. Open a command prompt and execute the following commands: cd %windir%\system32\inetsrv appcmd set config "Default Web Site/ews" -section:requestFiltering -requestLimits.maxAllowedContentLength:51200000 appcmd set config "Default Web Site/owa" -section:requestFiltering -requestLimits.maxAllowedContentLength:51200000 3. Edit C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\ews\web.config and change the maxReceivedMessageSize value to 51200000 underneath the <EWSMessageEncoderSoap11Element /> 4. IISreset to apply the change After making these changes OWA access now allows for the larger attachments. But Mac Mail clients are still receiving "Your message exceeds the maximum size allowed by the Exchange Server" error message when trying to send any attachment over 90MB. Does anyone know where I should look next for increasing attachment size in EWS? Also looking for tips on how to track down error messages in Exchange regarding email submission being rejected. I have found that either of these commands only show messages that are being submitted to SMTP but does not appear to show failed messages that are submitted to EWS Get-MessageTrackingLog -EventID FAIL | where {$_.RecipientStatus -like "*SendSizeLimit*"} Get-MessageTrackingLog -EventID FAIL | where {$_.RecipientStatus -like "*RecipSizeLimit*"} Any help would be greatly appricated!
