Good Morning
We are detecting some random errors while sending messages through OWA.
"too many concurrent connections opened"
This happen randomly to few our users (2% of total) and NOT located in the same network. We are on Exchange Online and end users use Owa only
.
Could this issue be related with our ESET Protect Server setting (mail scan or similar)?
I found this KB but it should be related to exchange on-prem
Thank you
