[outages] Email to Microsoft Office 365 users

[Frank Bulk]

I just pored through our own email logs – the issue first cropped up at 4:17 pm Central and the last failure I see is 5:01 pm, Central.  But looking at delivery, the last delivery was at 4:22 pm and the first delivery was at 4:58 pm.  So different domains may have started resolving at different times.

I received two confirmations off list of the issue – thanks.   The one observed it from 4:27 pm and 5:11 pm, Central.

 

Josh, you were checking just the MX records, but before any email server can actually connect to the email server it has to resolve staples-com.mail.protection.outlook.com, which was not working at the time of my original post.

Anyone else seeing this?  A colleague says that O365 is having issues and
will be forwarding me some details.
