Email Overview

Every Schreiner University student and employee is issued a username and password for email, network, and Schreiner One. You can access your email directly from the web here. As an official campus communication format, accounts should be checked regularly.

Outlook Web Access

a.k.a., OWA or simply "webmail" -- provides access to your Exchange email messages, calendar and contact information using only a Web browser. It provides most of the functionality of installed Outlook or other email client software.

For Windows PCs, OWA works best with Internet Explorer (Microsoft's Web browser), but can also be used with alternative browsers such as Firefox, Chrome, or Opera. For Apple/Mac systems, OWA works with Safari (Apple's Web browser), but also Foxfire, Chrome, Opera, etc.

Spam, Phishing, & Viruses


Spam is unwanted or unsolicited material that travels via email (commonly spam includes advertising or marketing in some fashion or another). Schreiner University has measures in place to reduce and block much of the spam that is aimed at our users and network. However, it us your responsibility to evaluate messages and files that are sent you. The best indicator that you have been sent spam is to examine closely the contact name and email address of the sender. If you suspect the message is spam do not open the email, simply delete the message. If the same message is sent to you repeatedly, block the sender or contact the Help Desk.


Phishing is an attempt to route the receiver of an email message to web document (webpage) where you will be instructed to enter your username and password, or in some cases your personal information. Internet scammers are very talented in reproducing popular webpages to look like the real thing (this can include bank websites, email websites, and social media websites). It is in your best interest to be vigilant and inspect the webpage and URL closely before entering any sensitive information. Generally you are not sent email from an individual or company you don't already have an existing relationship with and be instructed to enter sensitive information.


Computer viruses implant instructions in other programs or storage devices, and can attack, scramble, or erase computer data. The danger of computer viruses lies in their ability to replicate themselves and spread from system to system. Few computing systems are immune to infection.

Mailbox Size Limit

Maximum mail size limit for an individual message is 5 MB.  Anything over this limit will not pass through our server, inbound or outbound to your account.

Certain types of files (i.e., executables and compressed) are automatically blocked.  If you have need of such files, please contact the Help Desk.

Mailbox size limit is as follows: 200 MB - warnings from the Network Administrator; 225 MB - can no longer send mail; 250 MB - can no longer send or receive mail.  You can check your mailbox size by right-clicking on “Mailbox”, then left-clicking on “Properties” and finally on “Folder Size”.  Don’t forget to empty your” Sent Items” and “Deleted Items” occasionally.

Personal folders (.PST)  allow you to create and organize folders and keep your mailbox size under control.  Please note that you will not be able to access these personal folders through OWA (Outlook Web Access).  By default, the limit for a .PST file in Outlook 2007 and in Outlook 2003 is configured to be 20 GB.  Please contact the Help Desk if you reach this limit.
