It is possible to open project in Microsoft Project (MSP) (read and write) mode if this project is opened by other user in MSP (read and write) mode in the Modern User Experience (UX). Then, the information in MSP is wrong. No predecessors are visible, start and finish dates for tasks are incorrect, etc When the project is opened in MSP, the user is not able to see that the project is locked in the New UX. Users are also able to open locked projects using Open Workbench (OWB) in read/write mode.
Expected Results: The option to open the project in 'Microsoft Project Read-Write'(or OWB) is not available since the project is locked.
Actual Results: The option to open the project in 'Microsoft Project Read-Write' (or OWB) is available and selecting it open the project in MSP/OWB. Once the project opens, it is noted that the predecessor and successor columns are blank. If User1 releases the lock on the project and User2 does not notice that the dependencies are not included in the file and is able to save the project back to Clarity, the task dependencies are deleted from Clarity as well. Note that if the project was opened by User2 as Read Only, the task predecessors and successors do appear on the project mpp.
