About your storage space on the Exchange server

On this page:

Default storage capacity

By default, Indiana University Exchange mailboxes are allotted 50 GB of storage capacity. An increase can be granted (+25 GB) when mailbox storage exceeds 90%.

Determining the size of your mailbox

To determine how much data you have saved in your Exchange mailbox (i.e., Inbox and folders), see Check your storage space on the IU Exchange server.

Working with institutional data

IU Exchange accounts are appropriate for storing institutional data elements classified as University-internal.

Official classification levels for institutional data at IU are defined by the university's data management rules and policies. If you have questions about the classifications of institutional data, use the Data Sharing and Handling (DSH) tool or contact the appropriate Data Steward.

To determine the most sensitive classification of institutional data you can store on any given UITS service, see the Choosing an appropriate storage solution section of About dedicated file storage services and IT services with storage components appropriate for sensitive institutional data, including research data containing protected health information.

Do not send or receive Restricted or Critical data via email unless it is required by your role within the university. Instead of email, use Slashtmp Critical, Box Health Data Accounts, or Box Entrusted Data Accounts to share any Restricted or Critical data. If you are sharing personally identifiable information (PII) data classified as University-internal (e.g., names, University IDs, student addresses, etc.) via Exchange mail, best practice is to limit the data set to 100 or fewer individuals; to share larger data sets, use Slashtmp or Box Entrusted Data Accounts. If you are unsure whether email is appropriate for a particular situation, consult with the appropriate Data Steward and the UIPO. Always force encryption for messages that contain Restricted or Critical data. This is especially important since any recipient may forward messages you send or have IU email configured to automatically forward all messages to an outside email account. IU mail servers use the Cisco Registered Envelope Service (CRES) to encrypt messages sent to external recipients. For more, see About confidential information in email.
