Find out if POP and IMAP are being used

[Joe Beaton]

Hi,

Does anyone know of a way to find out if any accounts are connecting with POP or IMAP, we want to turn these off, but would like to know first if they're being used.

Thanks

Have you looked at the Usage reports in the O365 Admin center, namely the "Email app usage" one: https://portal.office.com/adminportal/home#/reportsUsage/EmailClients

Make sure to click the Export button to get all the info, or adjust the columns to include POP/IMAP.

I exported the data.  Vasil what do you think "Undetermined" means?  POP3 and IMAP columns have this value.  Does it mean "yes POP3 is being used but cannot determine client software being used" ?

Yes, that's my take on it.
