Office 365 Email FAQ
Following are some frequently asked questions about the email services provided by Office 365.
Office 365 is a subscription service from Microsoft which provides productivity software and related services to its subscribers. All MSU Denver students & employees are given an Office 365 account when they become enrolled/hired. The services provided through Office 365 include an online (“cloud”) email service offering 50 GB (gigabytes) of mail storage (quota), use of many of Microsoft's Office line of software products (Outlook, Word, Excel, etc.), and other collaborative features, such as Exchange calendars.
Here are the limits on email within Office 365. These are set by Microsoft and we cannot change any of them.
- Quota: 50 gigabytes
- Maximum number of recipients per message: 500
- Maximum size of attachment sent/receive: 25 megabytes
- Maximum number of recipients per day: 10,000
These are very high limits, but in a few rare cases, you may encounter one of them, especially if you frequently send emails to large numbers of recipients. If you reach 10,000 recipients in a day, your email will be locked for 24 hours by Microsoft and we will not be able to unlock it!
Yes, spam filtering is built in. Messages the system determines are spam will be delivered to your Junk Mail folder for you to examine; if you tell the system that certain messages are not junk, it will adjust its criteria accordingly.
No, MSU Denver Office 365 accounts only persist for people with active relationships with the University. Specifics time ranges depend on the type of relationship.
Student accounts last for three semesters after the last semester where the student completed a class. Summer semester is included in the count.
- The account of a student who graduated in Spring 2020 will expire at the end of Spring 2021.
- The account of a student who took classes in Spring 2020, began taking classes Fall 2020 (or Summer 2020), but then dropped all their Fall classes and didn't register for subsequent semesters, will expire at the end of Spring 2021.
- In the case of a student who was admitted to the University but never registered for classes, the account will expire three semesters after the semester they were admitted to register for (if admitted for Fall 2020, will expire at the end of Fall 2021).
Employee accounts expire at the end of the position's last day as marked in Banner.
Outlook 2016 and newer supports Office 365. Older versions of Outlook may also be compatible, but are not supported by Microsoft.
All versions of Mac Mail still supported by Apple (usually the three most recent versions of macOS) support Office 365.
There are no known incompatibilities with other mail clients (e.g. Thunderbird), but we recommend you only use up-to-date clients.
Yes. Instructions for setting up your Office 365 email on an Apple or Android mobile device can be found on our Office 365 Email page.
According to Microsoft, the full features of the Outlook Web App will be available in the latest versions of Edge, Internet Explorer, Firefox, Chrome, and Safari. Older versions may be supported as well, but Microsoft generally recommends using the most recent version of your preferred internet browser; older versions of a given browser may not have access to all of the Outlook Web App's features, may revert to the Outlook Web App Light, or may not work with Office 365 at all. For more information, please see Microsoft's article on Office 365's System Requirements.
The email connection types (Exchange, POP, IMAP, and SMTP) all support SSL encryption to secure your connection, and the web mail client uses https to secure your connection.
Yes. The Active Directory Domain Service stores passwords in form of a hash value representation of the actual user password. The Password hash cannot be used to log in to your on-premises network. It is also designed so that it cannot be reversed in order to gain access to the user’s plain text password. To synchronize a password, the Directory Sync tool extracts the user password hash from the on-premises Active Directory. Additional security processing is applied to the password hash before it is synchronized to the Azure Active Directory Authentication service.
Office 365 provides the ability to encrypt data at rest by supporting technologies that can encrypt the content of emails and/or files. The supported technologies for data encryption at rest include Microsoft’s Information Rights Management (IRM), S/MIME and PGP Email encryption and have the advantage of allowing the customer to maintain full control over the encryption infrastructure and key management on their premises.
Office 365 support for data encryption at rest technologies is designed to minimize the risk of information leakage by encrypting the content, allowing access only by the intended users and by extending the protection beyond the initial publication location. Microsoft’s IRM goes further by restricting the actions allowed on the protected content and also encrypting Office application document attachments.
Office 365 mitigates against the risk of unauthorized physical access with extensive physical protections in their datacenters and operational procedures.
MSU Denver's Office 365 license provides access to a wide range of features, including online Office applications, Skype for Business, SharePoint, and more. Microsoft maintains a full list of services available through their education plans. MSU Denver is currently signed up to the Office 365 A5 plan.
Yes, they are supported, and PST file functionality is the same as in older versions of Outlook.
