cuCollab is deprecated: New cuCollab sites are no longer being created Existing cuCollab sites will remain accessible as long the server remains operational, but no new memberships should be expected to be added. 

Carleton committees and working groups are encouraged to consider the use of Microsoft Teams, which provides a superset of cuCollab capabilities for document sharing, collaboration, and online meetings. The Service Desk can provide consulting on the use of MS Teams, as well as assistance in migrating files from cuCollab to Teams.
