The SPF permerror Office 365 causes email non-delivery and happens when **multiple SPF records** exist on a single domain, a syntax error occurs, or the [SPF 10-DNS-lookup](https://www.autospf.com/) limit is exceeded. The SPF permerror is different from the [SPF neutral](/content/spf-permerror/spf-neutral) message, where the domain owner is aware of the outcome. The most common of these SPF errors is the “too many DNS lookups,” error, treated as an [SPF fail](/content/spf-permerror/spf-fail) by DMARC if there are more than 10 DNS mechanism lookups. These mechanisms also include the ‘a,’ ‘mx,’ ‘ptr,’ ‘exists,’ ‘include,’ and ‘redirect’ modifiers.

With the errors found, a domain owner can work on eliminating them. ### Understanding SPF Permerror Office 365 Setting up SPF in Microsoft Office 365 is advisable to **prevent spoofing** and ensure efficient email delivery. However, the following things need to be kept in mind to avoid **SPF permerror Office 365**. - Create only one [SPF TXT record](https://www.namecheap.com/support/knowledgebase/article.aspx/317/2237/how-do-i-add-txtspfdkimdmarc-records-for-my-domain) for your custom domain. - Create separate records for subdomains. - Avoid exceeding the **10 DNS lookups limit**, lest the receiver’s mail server reports a permerror. - Check if the referenced domains are active to remove unnecessary domains from the SPF record. Email deliverability is one of the primary objectives when it comes to email authentication. **SPF authentication** errors such as SPF permerror and [SPF temperror](/content/spf-permerror/spf-temperror) act as hindrances to email deliverability. SPF permerror Office 365 can be avoided by taking the measures as mentioned above. ![spf fail](https://media.mailhop.org/duocircle/images/2020/12/spf-test-tools.png) ##### Join the thousands of organizations that use DuoCircle --- Find out how affordable it is for your organization today and be pleasantly surprised.
