August 2017 office 365 exchange online.
Office 365 smtp relay stopped working.
Thank them all for helping but it s not you.
I have two different unrelated office 365 that have stopped taking smtp over the last three or four days.
Microsoft 365 or office 365 smtp relay does not require the use of a licensed microsoft 365 or office 365 mailbox to send emails.
I took about 45 minutes after submitting the form for office 365 to start accepting emails relayed from this ip address.
Testing the office 365 smtp relay connector with powershell.
Microsoft 365 or office 365 smtp relay has higher sending limits than smtp client submission.
The remote smtp service rejected auth negotiation.
I set up my printer for microsoft 365 or office 365 smtp relay but it s not sending email or my device was sending email using smtp relay but it stopped working.
In this section we ll create some powershell scripts to allow you to easily ensure the connector is working properly.
After three days of troubleshooting i finally figured it out.
Relaying email via office 365 suddenly stopped working.
This can be caused by a number of issues.
Had a client whose smtp server suddenly stopped sending scan to e mails to their domain cloud office 365 e mail from their on premise smtp server.
Office 365 smtp relay quit working.
After creating the connector prepare to test it out.
A common reason for issues with microsoft 365 or office 365 smtp relay is a blocked ip address.
Relay via office 365 stopped working client host blocked using spamhaus.
The queue folder quickly filled up with over a hundred e mails so what could have caused this problem.
The easiest way to do that is to use powershell.
I also tried using the smtp server ip address instead of the domain name and tried using port 25 as well.
