This document defines the service level agreement for the Austin Exchange Messaging Service (AEMS).

Service description

The Austin Exchange Messaging Service (AEMS) is a collaborative e-mail, and calendaring service based on Microsoft Exchange. The AEMS environment is currently a hybrid of on-premise Exchange 2010 and cloud-based Office 365 Exchange Online (Wave 15). On-premise AEMS provides regular and automatic backup of e-mail and calendar entries, increased e-mail security, and enterprise-level architecture. Exchange Online provides geographic redundancy and a scalable enterprise architecture.

ITS will notify customers about both scheduled and unscheduled maintenance using the ITS Services Status page of service availability and service delivery issues. Services may not be available during the maintenance periods.

Scheduled maintenance

Scheduled maintenance occurs weekly on Sundays from midnight until 6 a.m. To the maximum extent possible, installation of service, application, and security updates will be performed during scheduled maintenance. Non-disruptive maintenance can also take place at any time outside of regular business hours.

Unscheduled maintenance

Unscheduled maintenance tasks that require service downtime will be announced as soon as possible on the ITS Services Status page.

Problem reporting and change notification

ITS will notify customers using the ITS Services Status page of service availability and service delivery issues for the Austin Exchange Messaging Service.

Account retention

Mailbox subscriptions may be canceled for any of the following circumstances:

  • Users may cancel their own subscriptions.
  • Departmental sponsors may cancel a subscription if the account no longer has a current University affiliation.
  • Individual is no longer eligible for a subscription (i.e. has departed the university).

Mailboxes with a security or related issue are deleted immediately if the Information Security Office (ISO) requests it.

When an AEMS mailbox subscription is explicitly canceled, the mailbox is immediately deleted. If the account becomes no longer eligible for an AEMS mailbox (no UT affiliation and the AEMS subscription not being present in a departmental TRAC group), the mailbox is deleted after 30 days. After deletion, the mailbox is retained in a disconnected state for 90 days if it is an on-premise mailbox, or 30 days for cloud mailboxes. After the retention period has expired, the mailbox content cannot be retrieved.

AEMS subscribers agree to:

  • Read the AEMS documentation.
  • Patch desktop as recommended by vendor.
  • Use supported Exchange client software
  • Provide critical information to ITS in a timely manner when requested for purposes of resolving subscriber issues.

In addition to the items listed above, departmental IT support staff agrees to:

  • Provide ITS with contact information for departmental TSC through your ITS contact, and notify ITS of changes.
  • Designate at least one secondary TSC for each department.
