Hello everyone,
I'm pretty new to Adobe Campaign Classic and i'm facing an issue concerning the publication of a template using transactional messaging in my Message center folder > Transactionnal message templates.
I'm getting this type of error.

It's about the resolving address, which is not the same in the Administration folder > Platform > Options of my company, so I try to change the address by the one I got in the error but it didn't update so I don't have a clue of what to do.. Maybe the sandbox needs a restart ? Or maybe it's something else ?

I'm using Adobe Campaign Classic V7 with a Windows10. If you need more informations, feel free to ask.
Thanks for you help.
