There is enough information stored in the database to obtain this information to a certain level. Running the following SQL query on the database called NME40DB:
SELECT C.Name CollectionName, T.Name TaskName, WIR.WorkItemType, WIR.StartTime, WIR.State FROM NME40DB.dbo.T_NMECollections C INNER JOIN NME40DB.dbo.T_NMETasks T ON C.NMECollectionGUID = T.NMECollectionGUID INNER JOIN NME40DB.dbo.T_NMETaskRuns TR ON T.NMETaskGUID = TR.NMETaskGUID INNER JOIN NME40DB.dbo.T_NMEWorkItemRuns WIR ON TR.NMETaskRunGUID = WIR.NMETaskRunGUID ORDER BY C.Name, WIR.StartTime DESC
The work item type number returned from the query tells you some of the information:
5: Provision
6: Notes data locator
9: Send PAB replicator
10,11,12: Manage mail routing
10,11,12,15: Mailbox creation
10,11,12,14: Mail file was migrated.
10,11,12,13: Archive was migrated.
10,11,12,15,16: Admin activities were performed, but not specifically which admin activities.
