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 the storage space of your IU Exchange account.

Working with institutional data

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

Official classifications for institutional data at IU are defined in Management of Institutional Data (DM-01). If you have questions about the classifications of institutional data at IU, see Classification levels of institutional data, use the Data Sharing and Handling (DSH) tool, or contact the appropriate Data Stewards. To determine the most sensitive classification of institutional data you can store on any given UITS service, see Choose an appropriate storage solution.

Important:

Do not send or receive Critical or Restricted data via email unless it is required by your role within the university. Instead of email, use Secure Share to share any Restricted or Critical data. If you are sharing personally identifiable information (PII) classified as University-Internal data (for example, 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 Secure Share. If you are unsure whether email is appropriate for a particular situation, consult with the appropriate Data Stewards 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 Office Message Encryption (OME) to encrypt messages sent to external recipients. For more, see About confidential information in email.
