Background
By default, when sharing files or folders through OneDrive, sharing permissions will be set to "People in Northeast Ohio Medical University with the link." Due to security policies, "anyone" links are disabled.
If you need to share with those outside of NEOMED, please see the following section.
How to Share with Those Outside of NEOMED
When you share a document through OneDrive by right-clicking on the document you want to share and selecting ‘Share’, the following prompt will appear.
When you select ‘Specific people’, you’ll need to determine if these individuals you’ll be sharing the document with should have editing access and the ability to download the document to their devices. You can enable those settings in the ‘Other settings’ section picture below. By default, editing is not enabled, and downloading is enabled.

When you then select ‘Apply’, you’ll then be prompted to enter the email addresses of those who should have access to your document within the “To: Name, group or email” section. Once you’ve added the individuals that should have access to your document, you can then select ‘Copy link’ at the bottom. In the below example, I entered two email addresses and then am about to select ‘Copy link’.

You’ll then be presented with a link that you can copy into an email (select ‘Copy’) and send to those individuals that you provided access to in the step prior.
