What are the problems with sharing an Access database through online storage service, like Dropbox? I have a desktop database I created in Access. I'd like to share the database with a single collaborator, who can have full privileges to the database (table access). However, my collaborator is much less tech-savvy so to make it easier for him, I have set up forms to make table updates, so table access is not a must for him. With that in mind, I am willing to split up the database if this would be a better option.

I had considered sharing the database with him over a Sharepoint website, but have little experience with this and would not know where to begin. I also do not think it would be worth the (relatively low) monthly price to share with a single person. I do not expect our team to grow either, so there is no need to prepare for this. I think the best option is to share the database on Dropbox so that we both have the same version to work with. I've read some forums posts on doing those and all seem to discourage sharing Access databases like this. However, I've had a hard trouble understanding, as I am a novice. There is no need for us to both be able to work on the database at the same time, but I have no idea how I can restrict access to a single user at a time. Can you please explain what the problems are with sharing an Access database in simple terms and what workarounds there is, if any? 

Please don't suggest other options as I am trying to keep this project as simple as possible and my experience with SQL is minimal. Plus, I need to keep this simple for my collaborator as well and this is a sort of personal project I don't have a ton of time and resources for. 

Thank you for the help!
To put it simply - it would work if only one of you were editing the database at a time. If both of you were to edit the database, it could corrupt the file, discard each other changes or cause sync issues.

By the way, have you considered Google Docs?
