Today, based on feedback, we’ve lowered the timeout to 24 hours. In the future, we are planning more improvements, although we do not have any dates or details to share at this time. Thank you for the continued feedback.Fabian Melchior commented
Mail is unreliable now. 48 hours for a NDR is way too long these days. This is a big issue for my customers. If this problem isn't going te be solved asap, many of my customer will leave Office365 and use other mailsystems.
If the interval time can't be changed at the moment, please profit a delaynotification after 1 hour, with the message that the emailserver will be try delivering the mail for teh next 48Hours.Fabian Melchior supported this idea ·
