Configure attachment size OWA Exchange 2013

I have recently installed an Exchange Server 2013.
I have setup in all Send and Receive connectors a maximum message size of 100MB, through the EAC.
That works fine for Outlook.

However, in OWA, when trying to attach anything larger than 5MB, I get:
"The following files weren't attached because adding them would cause the message to exceed the maximum size limit of 5 MB"

I found this article explaining how to change the message and attachment size limit for OWA, using notepad (really) to edit manually 27 (yes, 27!!) entries in a bunch of config files.
http://technet.microsoft.com/en-us/library/hh529949.aspx
I went thoroughly through all of them, changed them, and rechecked each one.
I ran a IISRESET after that.
I still have the problem.

I don't know where that '5MB' limit is coming from, but threre wasn't anything in the config files set to 5MB before the change (they were settings to 10MB, 35MB and 64MB, I think) so I'd guess this limit is coming from yet another location that I didn't find yet.

Go to Exchange Management Shell, and type the following command:

Set-transportconfig -MaxSendSize: 100000

OWA does not know how to interpret Unlimited values.

or

Go into "Organizational Transport Settings" and change "Maximum receive message size" and "Maximum send message size" to 100 mb

run these cmdlets from Exchange management shell and see what results you get.
get-receiveconnector | foreach{$_ | select Name,Maxmessagesize}
get-sendconnector | foreach{$_ | select Name, MaxMessageSize}
get-transportconfig | select MaxReceiveSize, MaxSendSize

I'm sorry, I had already setup that limit, I wasn't clear about that.
I checked using
Get-TransportConfig | fl  
and this is the output:

Just in case, I also checked in "Organizational Transport Settings" and both "Maximum receive message size" and "Maximum send message size" showed up as 100 MB.

Just in case, I did another iisreset, but the problems continued.
I checked from IE, Chrome and Firefox, from 2 different computers.
I can attach things up to 5MB but when I go beyond that limit, either with one or the sum of attachments, I will get that error message.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I ran all the commands suggested by :

get-receiveconnector | foreach{$_ | select Name,Maxmessagesize}
get-sendconnector | foreach{$_ | select Name, MaxMessageSize}
get-transportconfig | select MaxReceiveSize, MaxSendSize

and each value returned was 100MB

you need to restart the exchange server, not just IIS.

You may be able to get away with restarting the "Exchange Information Store" service instead of the entire machine.

The link that you refered http://technet.microsoft.com/en-us/library/hh529949.aspx under Outlook Web App section some of the size is mentioned in bytes and kilobytes, did you convert the value correctly?

In the end, it was a stupid thing.
I had already made all changes needed, but a restart of the exchange server, instead of a iisreset, was needed.
