Office 365 Email and Calendar Account
Also known as: Office 365; Email for Faculty and Staff (Office 365); Calendar for Faculty and Staff (Office 365)
Available to: Faculty & Staff
Office 365 is the university's email and calendar system for faculty and staff. It is fully supported by the ITS Support Center and can be accessed via the login at Office365.gmu.edu by using your Mason credentials (Mason NetID and Patriot Pass password).
Office 365 email accounts contain the @gmu.edu domain name.
Data within the Office 365 system is not backed up by George Mason University. Account holders are responsible for backing up their own data and preserving copies of important messages and attachments.
Office 365 is a Cloud-based system that is available from any Internet-enabled computer or mobile device and provides 25 GB storage, reliability, antivirus, and anti-spam features.
There are multiple email limits for Office 365.
- The maximum number of recipients in the To:, Cc:, and Bcc: fields is 500.
- 30 messages can be sent out per minute.
- 1,500 recipients can be emailed per 24 hours. After the limit is reached, you will not be able to send out messages until your total sent messages drops below 1,500. This is a rolling limit meaning if you email 1,500 people at 10 a.m. on Monday, you will not be able to e-mail anyone again until 10 a.m. on Tuesday.
- The maximum message size is 25 MB including message body and attachments.
There is no limit on the amount of messages that can be received provided that the total size of all of the saved messages does not exceed the 25 GB quota. The system will support personal archiving for those that have a need to save more than 25 GB worth of messages. In the personal archive, the messages are moved from the inbox to a different set of folders specifically designed for archive purposes. The limits set by Microsoft on the number of messages that can be sent cannot be altered. The Messaging team can work with customers who have needs that exceed the limits set by Microsoft.
Users of Office 365 are responsible for all activity on their accounts, including password resets and abuse, and must adhere to University Policy Number 1301: Responsible Use of Computing.
