Hello,

I have an issue with Exchange 2007 and OWA 2007 on IIS7. On our LAN, I'm able to attach 20+MB in OWA. However, when I'm on an external connection, I can only attach less than 10MB. It's not the internet connection, because I'm able to attach a 9MB file within seconds. But once I go above 10MB, it just thinks for 10 minutes and then times out, without any error.

Settings:

25MB send and receive limit within Exchange 2007

Internally, I can attach more than 20MB via OWA

Externally, I cannot attach more than 10MB via OWA

Any ideas where I might start looking? What kind of setting would affect an internal OWA connection and not an external OWA connection?

Thanks!

Yes, there are a couple of steps that you need to perform. If the Exchange 2007 server is running on Server 2008, you need to configure OWA to allow content that is equal to the size of the maximum message size as well.

A simple search will get you the step-by-step instructions that you are asking for.

Thank you for your reply. I've actually scoured the internet looking for solutions or a setting I might change. Your link takes me back to those same articles. I've verified those settings are 25MB send/receive, unlimited MaxRequest and MaxSubmit settings, etc. I've even tried changing appcmd requestfiltering settings.

I thought it redundant to mention these, though, because I'm able to do exactly what I need to through OWA when on the LAN, just not externally. If I'm able to do what I need through OWA internally, should I even be looking at Exchange or OWA settings, or looking elsewhere? That's what I'm trying to find out... what could be the difference in Exchange/OWA/IIS if I can do exactly what I need to from my computer at work?

I selected public mode when logging into OWA internally and externally, so that's not the difference.

Thanks
