Scroll to the TXT records section and add a new record with the SPF values. Under the Text section, enter (without a full stop). This guide will show you how to add two SRV records for Office 365. Next, click on the 'view/manage your domains' section in the control panel. The use of Name Protection in the Windows Server® 2008 R2 operating system prevents name squatting by non-Windows-based computers. If there is no timestamp, such as a manually created, static record, it will not get scavenged.“ DHCP Name Protection The DNSupdateproxy group must be secured if Name Protection is enabled on any IPv4 scope Credentials for DNS update should be configured if secure dynamic DNS update is enabled and the domain controller is on the same host as the DHCP server Also, if all servers, including DCs, are automatically updating their own record, then there is no fear of losing their records, because for one, their records (timestamps) are current, therefore scavenging won’t touch them, and two, Windows Servers by default will update their records every 24 hours, with the exception of domain controllers at every 60 minutes.This is so that you can use your domain email with Office 365.Log in to your Squirrel Hosting customer control panel.

Scavenging Refresh and No Refresh settings must be equal to or less than the lease period.Therefore, even if they were to scavenge these records, assuming the time stamp has ever been reached, the machines will refresh themselves anyway! By default, statically configured clients and remote access clients that do not rely on the DHCP server for DNS registration, will re-register their A & PTR records dynamically and periodically every 24 hours.This applies to Windows 2000 Professional and all newer operating systems.This is because the client will not update itself due to the current record in DNS is beyond the lease period.This happens even though DHCP registered the record.
