We don't recommend sharing or attempting to sync Quicken data files between computers on a network, as this may lead to data file damage. We also strongly advise against installing Quicken on a network. Quicken is not designed to be used over a network or shared drive.
Quicken incrementally saves your data as it's entered. Saving Quicken data files locally (directly on your computer's hard drive), and not over a network, decreases the risk of data loss. Network instability or the use of a single data file by multiple people at the same time will often lead to data integrity issues.
Due to the many possible network configurations, Quicken doesn't offer technical assistance for this type of configuration.
