Securing legacy email

[Joe]

Hi,

We are still using IMAP. I hope this question makes sense. Can you please give us the source IP address range(s) you make connections from Hornbill to our Office365 tenancy for IMAP/SMTP access for email integration. We need to further restrict mailbox access to legacy protocols and want to put an IP access restriction in for Hornbill which requires ongoing legitimate access.

Cheers
