Challenge #9
Secure Sharing with Automatic Guest Expirations
Implement automatic expiration for guest access in SharePoint and OneDrive. Ensure your external collaborations are both productive and secure.
Why?
Collaborating with external partners is vital, yet it brings its own set of security challenges. Granting guest access to SharePoint and OneDrive via file shares, Microsoft Teams invites or related is a common practice, but without proper controls, it can leave our data vulnerable. By setting automatic expiration for guest access, we add a layer of security that adapts to the dynamic nature of collaboration.
This approach ensures that external partners have access only for as long as they need it, typically recommended for no more than 30 days. After the set period, access expires automatically, reducing the risk of outdated permissions lingering and potentially becoming security loopholes. It’s about creating a secure environment where access is granted judiciously and monitored continuously, aligning with the best practices for data protection.
How?
Configuring automatic expiration for guest access in SharePoint and OneDrive is a straightforward but critical step in enhancing your collaborative security. Here’s how to get that gap closed up.
Step 1: Go to the Microsoft Sharepoint Admin Center
On your computer, launch a new browser window (Edge, Chrome), and type in https://admin.microsoft.com/sharepoint and press enter.
Note: You will require Microsoft 365 administrative credentials – be sure to have the username and password ready.
Step 2: Adjust Sharing Policies
Within the Microsoft Sharepoint Admin Center:
- Look for and select Policies
- Under Policies, select Sharing
Step 3: Configure External Sharing Settings
- Within the Sharing window, find and click More external sharing settings (it’s an expandable menu).
- Under More external sharing settings, find and enable the setting for Guest access to a site or OneDrive will expire automatically after this many days
- Once enabled, you can then define the days in which you are comfortable with, ranging from 30 to 730 days.
- We recommend 30 days
PS. For bonus points, there are several other settings on this page that can improve security and your Secure Score, such as default permissions for sharing links (view vs. edit), defaults for who can use the links when you share files, and several others. Explore.
Step 4: Confirm and Save Settings
- Once you are satisfied with your changes, click Save

Cloud Journey #3: Your Cloud Journey
It’s important to think of your move to the cloud as a planned journey instead of an overnight switch. And, as with all journeys, the key is to establish where you are, where you want to be and how you’ll get there.
Cloud Journey #2: Outdated IT is Weighing you Down
Information technologies, from PCs and networks to the internet and smartphones, have given a massive boost to growing businesses. But today, many companies are struggling to manage and maintain all of the technologies they’ve acquired over time; forced to throw more and more time, money and resources at IT instead of into their core business, ending up less secure and less productive. The cloud changes all that.
Part 1: The Start of your Journey to Cloud
In most markets, big businesses used to hold all the cards, with the best, most advanced IT systems to automate and streamline their processes. Today, a major revolution is turning this trend upside-down, as smaller companies disrupt whole markets with new ideas and new technology, all powered by the cloud.
