3. The University is required to notify the government or affected individuals if the data is inappropriately accessed; and/or
4. The loss of confidentiality, integrity, or availability of the data or system could have a significant adverse impact on the University’s mission, safety, finances, or reputation

For assistance with handling such data, please contact Information Security

To ensure the appropriate level of information protection and privacy for the data stored in these
applications, members of the York community must classify data based on the level of sensitivity and value of that data. More information on data classification can be found in York’s Information Security Classification Standard.

The table below lists which information classifications can be used in different Office 365 applications:

Office 365 contains several useful sharing features that enable access to multiple people of the same information. When using these features, you are responsible for ensuring the access is appropriate and
properly maintained over time. Keep these tips in mind:

• Share files with specific individuals or groups, do not use ”share with everyone”;
• Use folders to share groups of files with others;
• Remember that once a file is shared with someone, they can download it to their device and share it with others; and remove access when individuals no longer require access to files or folders.

Third party copyrighted materials, such as book chapters, journal articles, music, videos, etc. or materials that
have been licensed by York University Libraries, may not be shared with students via Office 365 services such as OneDrive for Business, SharePoint or OneNote, Groups, Teams, etc. Online course materials should always be made available to students via York-supported Learning Management Systems, such as Moodle. York’s faculty and staff are responsible for using copyright-protected materials appropriately.

No. It is clearly addressed in the Microsoft online services agreement that they can not.

Yes!

Microsoft’s contractual commitment restricts any use of information in or about YU accounts to use required to deliver the service. For example, Microsoft's automated services will scan incoming mail information in order to implement mail filters.

No. The terms and conditions include provisions that allow York to move our accounts elsewhere if we so wish.

The new spam filters in O365 have different rules for catching spam than our previous environment; as a result, some emails that previously went to your inbox may go into your junk mail folder after the migration. <a href="https://support.office.com/en-us/article/Block-or-allow-junk-email-settings-48c9f6f7-2309-4f95-9a4d-de987e880e46">Learn more about junk mail with O365.</a>
