We are getting a weird results, when the delivery is sent from adobe campaign classic, at first the status in the broad log RCP table is showing as sent for the particular recipient and we pull the report for that delivery which we send to the business. Later afterwards we send the weekly deliveries report where we see the recipient for the same delivery is seen as failed and the most common failure reason we are seeing is "Mailbox Full".
Just wanted to check if this situation has occurred to any; if so how to resolve such issues.
this is normal. When a message cannot be sent to a profile, the remote server automatically sends an error message, which is picked up by the Adobe Campaign (bounce) and updated in broadlog. AC will try 5 times by default. Mailbox full error is the soft error and this type of error is managed by a clean-up process, the address is set to a valid status again after 30 days.
