Many also choose the subscription service for its robust security features designed to safeguard against cyberthreats of all kinds. To make the most out of these functionalities and ensure your business data’s security, follow these tips. **Take advantage of policy alerts** Establish policy notifications in Microsoft 365’s Compliance Center to help you meet your company’s data security obligations. With these in place, your employees will receive policy tips about sending confidential information anytime they’re about to send messages to contacts outside of the company network. These preemptive warnings can prevent data leaks and also educate users on safer data sharing practices. **Secure mobile devices** Since employees often use personal smartphones or computers to access their work email, calendar, contacts, and documents — especially if they’re working remotely — securing employee-owned devices should be a critical part of protecting your organization’s data. Installing mobile device management features for Microsoft 365 enables you to manage security policies and access permissions/restrictions, and remotely wipe sensitive data from mobile devices if they’re lost or stolen. **Use multifactor authentication** Relying on a single password to protect your Microsoft 365 accounts could lead to account hijacking, which could put your data at risk of being compromised. Instead, enable multifactor authentication (MFA). MFA requires users to supply additional credentials on top of a password before they can access their accounts. This makes it difficult for hackers to access your accounts since they not only have to guess user passwords, but they also need to provide a second authentication factor like a one-time code or a fingerprint scan. **Apply session timeouts** Many employees usually forget to log out of their Microsoft 365 accounts and keep their computers or mobile devices unlocked. This could give unauthorized users unfettered access to company accounts, allowing them to steal sensitive data. By applying session timeouts to Microsoft 365 accounts, email accounts, and internal networks, users will be automatically logged out after a period of inactivity, preventing hackers from taking over users’ devices and accessing private information. **Avoid public calendar sharing** Microsoft 365’s calendar sharing feature allows employees to share and sync their schedules with their colleagues. However, publicly sharing this information is a bad idea because it helps attackers understand how your company works, determine who’s away, and identify vulnerable users. For instance, if security administrators are publicly listed as “Away on vacation,” an attacker may see this as an opportunity to unleash malware on unattended computers. **Employ role-based access controls** Access management is another Microsoft 365 feature that will limit the flow of sensitive data across your organization. It lets you determine which users have access to specific files in your company. For example, rank-and-file employees won’t be able to read or edit executive-level documents, minimizing the risk of data leaks. **Encrypt emails** Encrypting classified information is your last line of defense against data breaches. If hackers intercept your emails, encryption tools will make files unreadable to unauthorized recipients. This is a must-have for Microsoft 365, where files and emails are shared on a regular basis. If you’d like more information on the variety of ways that Ashton can help to secure your Microsoft 365 accounts, give us a call at 216-397-4080.   By [Ashton Solutions](https://www.ashtonsolutions.com/the-ashton-solutions-blog/author/ashton-solutions) August 2, 2021 [Managed IT](https://www.ashtonsolutions.com/the-ashton-solutions-blog/tag/managed-it) --- ### You Might Also Be Interested In: ![MSP 501 2026 Winner Logo\_White](https://www.ashtonsolutions.com/hs-fs/hubfs/MSP%20501%202026%20Winner%20Logo_White.png?width=1122&name=MSP%20501%202026%20Winner%20Logo_White.png "MSP 501 2026 Winner Logo_White") ![EOS](https://www.ashtonsolutions.com/hs-fs/hubfs/Ashton_March2026/images/EOS.png?width=104&name=EOS.png "EOS") ![Wealthead100](https://www.ashtonsolutions.com/hs-fs/hubfs/Ashton_March2026/images/Wealthead100.png?width=163&name=Wealthead100.png "Wealthead100") ![CRN26-MSP500-Horizontal-White](https://www.ashtonsolutions.com/hs-fs/hubfs/CRN26-MSP500-Horizontal-White.png?width=1742&name=CRN26-MSP500-Horizontal-White.png "CRN26-MSP500-Horizontal-White") - [Services](https://www.ashtonsolutions.com/services) - - [Managed IT](https://www.ashtonsolutions.com/services/managed-it) - [Co-Managed IT](https://www.ashtonsolutions.com/services/co-managed-it) - [Security](https://www.ashtonsolutions.com/services/security) - [Compliance](https://www.ashtonsolutions.com/services/compliance) - - [AI Solutions](https://www.ashtonsolutions.com/services/ai-solutions) - [Transaction Advisory](https://www.ashtonsolutions.com/services/transaction-advisory) - [Networking](https://www.ashtonsolutions.com/services/networking) - [IT Projects](https://www.ashtonsolutions.com/services/it-projects) - [Who We Support](https://www.ashtonsolutions.com/who-we-support) - - [Non-profit Organizations](https://www.ashtonsolutions.com/who-we-support/non-profits) - [Financial Services](https://www.ashtonsolutions.com/who-we-support/financial-services) - [Legal Services](https://www.ashtonsolutions.com/who-we-support/legal-services) - [Professional Services](https://www.ashtonsolutions.com/who-we-support/professional-services) - [Industrial & Manufacturing](https://www.ashtonsolutions.com/who-we-support/industrial-manufacturing) - - [Life Sciences](https://www.ashtonsolutions.com/who-we-support/life-sciences) - [Architecture, Engineering & Construction](https://www.ashtonsolutions.com/who-we-support/architecture-engineering-construction) - [Real Estate & Development](https://www.ashtonsolutions.com/who-we-support/real-estate-property-development) - [Other](https://www.ashtonsolutions.com/who-we-support/other-industries) - [About](https://www.ashtonsolutions.com/about) - [Meet the Team](https://www.ashtonsolutions.com/about#meet-the-team) - [Our Approach](https://www.ashtonsolutions.com/about/our-approach) - [Our Story](https://www.ashtonsolutions.com/about#our-story) - [Partners](https://www.ashtonsolutions.com/about#partnerships) - Resources - [Blog](https://www.ashtonsolutions.com/the-ashton-solutions-blog) - [Abbott's Thoughts](https://ashtonthoughts.com/) 23625 Commerce Park, Suite 130 Beachwood, Ohio 44122 Contact Us: [216-397-4080](tel:216-397-4080) - © 2026 Ashton Solutions | All Rights Reserved - [Terms of Use](https://50314096.hs-sites.com/terms) - [Security Policy](https://50314096.hs-sites.com/security-policy) - [DCMA Policy](https://50314096.hs-sites.com/dcma-policy) - [Privacy Policy](https://50314096.hs-sites.com/privacy-policy) [![Linkedin](https://www.ashtonsolutions.com/hs-fs/hubfs/Ashton_March2026/images/linkedin-icon.png?width=28&name=linkedin-icon.png "Linkedin")](https://www.linkedin.com/company/ashton-solutions) [![Instagram](https://www.ashtonsolutions.com/hs-fs/hubfs/Ashton_March2026/images/instagram-icon.png?width=28&name=instagram-icon.png "Instagram")](https://www.instagram.com/ashtonsolutions) [![Twitter](https://www.ashtonsolutions.com/hs-fs/hubfs/Ashton_March2026/images/twitter-icon.png?width=24&name=twitter-icon.png "Twitter")](https://twitter.com/AshtonSolutions) [![youtube](https://www.ashtonsolutions.com/hs-fs/hubfs/Ashton_March2026/images/youtube%201.png?width=32&name=youtube%201.png "youtube")](https://www.youtube.com/user/AshtonGroup/featured) ```json { "@context" : "https://schema.org", "@type" : "BlogPosting", "author" : { "@type" : "Person", "name" : "Ashton Solutions", "url" : "https://www.ashtonsolutions.com/the-ashton-solutions-blog/author/ashton-solutions" }, "dateModified" : "2026-07-14T01:13:09.975Z", "datePublished" : "2021-08-02T09:17:04.000Z", "headline" : "Microsoft 365 Data Loss Prevention: A Quick & Easy Guide | Ashton", "mainEntityOfPage" : { "@id" : "https://www.ashtonsolutions.com/the-ashton-solutions-blog/2021/08/02/microsoft-365-data-loss-prevention-a-quick-and-easy-guide", "@type" : "WebPage" }, "publisher" : { "@type" : "Organization", "logo" : { "@type" : "ImageObject", "url" : "https://www.ashtonsolutions.com/hubfs/Ashton%20Solutions%20logo_color.png" } } } ```
