Hi All,
This morning I am getting a lot of 502, 503 or 504 errors across various scenarios connected to different MS365 Outlook accounts. Manually running them a few times seems to eventually complete successfully, but I wondered if anyone else is having similar issues? I’m guessing the problem is at Microsoft’s end?
Cheers
Same problem since this morning. 
Glad it’s not just me! Hoping it is something at MS end and they can repair swiftly as the fail notifications are clogging up my inbox!
Same here, getting more now. Still this has not been fixed.
Several of my customers mention the same thing, let’s keep an eye on this.
Same here. Started slow and wasn’t effecting all our connections but it has picked up and is more widespread.
Not sure about anyone else, but all seem to be running fine again this morning!
