Hi Chris,
I've followed up with my customers who had this issue.
It seems they had Oulook.com checking their email accounts via POP3,
this had been setup for some time (years) and they hadn't touched or
changed it recently.
As the customers had since migrated to using IMAP and a local client,
they disabled this in the Outlook web interface and normal bandwidth
consumption resumed [0] with no issues of POP3 bandwidth usage since.
Hi Joseph,
Thanks for the info - I had a better look into my netflow records today
and its even more customers than I thought on our end who have this
setup - I am guessing something changed at the Outlook end which has
broken it (unlikely a bunch of different servers on our end, not even
running the same POP3 server software, all broke at the same time). Just
for today we are over 2.8TB and counting.
I guess I'll have to get the support team to start calling customers...
