InfoPath Dev

Hello all New to the forums - experienced user of InfoPath (both 2003 and 2007).

I have a form (InfoPath 2007) which users submit to SharePoint (2007) but not directly - they submit using e-mail. This is because users - when filling out the form - are not connected to the corporate network. Therefore, the form is submitted using e-mail (data connection in the form, activated by clicking button in the form). In SharePoint I have created a form library, published the form to this library, setup an e-mail for the library (feature of SharePoint 2007). This means that users can submit the form without being connecteed to the corporate network and I can launch workflows based on the form when created etc. - pretty clever, I think.

However, in the form users can insert pictures (not attach, but insert). This drives up the size of the InfoPath form - sometimes above a few MB. The problem is this: - Whenever the file size is above 1MB the user receives an error e-mail back within seconds stating that.

The error message included is:
"This message is larger than the current system limit or the recipient's mailbox is full. Create a shorter message body or remove attachments and try sending it again."

I have tried e-mailing the library with attachments larger than 10MB and it presents no problems - so it is not SharePoint or Exchange that have soem limit set somewhere as far as I see it (the Exchange setting was set to 20MB manually just to be sure as well as to the "default" size limit). It is only when using the submit as e-mail message in InfoPath and having pictures inserted that it goes wrong (without pictures of when file size is less than 1MB there are no problems)

Any-one has any idea as to what may be going wrong?
Cheers,

I have actually never experienced this problem but may be write some code and use the mailenvelope object instead of the InfoPath dataconnection. Like this the form will be attached to the mail as a file and also in html format in the body of the mail. Not sure if you can then still launch you workflow as I haven't suer MOSS 2007 & InfoPath 2007 yet. But you see you should always be careful with a statement like pretty clever, I think :). just kidding

Thx for your quick reply.

Unfortunately, I am not much into code and programming (read: i wouldn't know how to start or where) so I am afraid your solution won't fly for me. I was hoping that the issue could be resolved without resorting to code.

Additionally, I am not sure that just "by-passing" the InfoPath data-connection for submitting the form will solve the issue (but can't say 100%). When I look to my sent items, the mail items are there with the data attach (xml-file attached to the e-mail) - so that is how it is sent. So my thoughts are that somewhere along the way from Outlook to SharePoint something goes wrong.

Just a thought. How much space you have granted to cache temporary internet files in your internet explorer settings. can you check it, delete the cache and increase it at least up to 10MB. may be also try something like Set-TransportConfig -MaxReceiveSize 30MB -MaxSendSize 30 MB on your exchange server. Sorry also don't have any other idea but i am pretty confident that someone from the guys here can help out.
