UMSL Faculty and Staff can request events for One-Time-Only or Special Ad-Hoc Requests thru the new online system called 25Live.

Do NOT use this process for the following:

In 2013, UMSL implemented a Classroom Reservation Request system to provide an online process for any faculty and staff to request classrooms for special events. This replaced the Outlook series of calendars that had been used in the past, which are no longer used to determine classroom availability. 

Students will not be able to submit requests for classrooms. Faculty and staff will be required to make reservation requests on behalf of students who would like to schedule an event in a classroom. 

The Registrar’s Office will review and approve all room reservation requests and will contact you if there are any issues with the date/s or room/s you have requested.

Instructional Computing Support Services ( will continue to provide support for any of the classroom technology available and for the locking/unlocking of rooms.

NOTE: As has always been the case, classroom reservation requests during a semester cannot be made until the course schedule for that semester is complete and all courses are assigned to rooms. Once that is finalized, individual room requests can be submitted.

*Please note that new classes are being added to the schedules every day and official classes take precedence over ad-hoc events. In the event that a class is scheduled that conflicts with your event, we will contact you and attempt to make alternate arrangements.
