Hi,
We're using 2013R2.
When we are trying to use Rebex to send an email to an Office365 server with an attachment > 5MB we get the following error.
Is there any configuration on our side that we could be changing? If not, can anyone shed light on why Office365 would be closing down the connection? I am able to send an attachment of > 5MB through their web interface.
