Bypass / Ignore Exchange Server "Maximum Sending Size"?

As soon as possible I will begin the generosity and the reward of 150 (that I have) indicates a decision.

I am developing Outlook add. When a message is sent, add a message to the processes, it removes the attachments and sends them through another transmission channel and places links for loading the attachment in the message body.

When using Outlook with an exchange server with a maximum sending size, users cannot even attach large files to the message. Outlook displays a warning that imposes a restriction on sharing.

To degrade attachment, it is denied before any binding events are triggered.

I need a way around this behavior. Something that will allow users to add attachments of any size using the paperclip button for Outlook, or drag and drop. Or a good direction I can work on.

Adding a separate connect button is not an option.

Try setting the PR_MAX_SUBMIT_MESSAGE_SIZEMAPI property (DASL name http://schemas.microsoft.com/mapi/proptag/0x666D0003) with Store.PropertyAccessor.SetProperty.

OutlookSpy ( IMsgStore, , IMAPIProp::GetProps, PR_MAX_SUBMIT_MESSAGE_SIZE - ), , . , Outlook - .
