Hi all,
I’m using a group email to send out messages to CompanyA, however, I receive an error message
“The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.”
I checked in Exchange server that I have been granted Full control including Send As right. It looks like everything is alright.
When I send solely to CompanyA, I do not get this message. Confirmed with CompanyA IT support, they don’t have any filtering or blocking to my group email
Does anyone have an idea??
Please advice, thanks much!
Suzanne
