However, when you enable Mindjet Files and Tasks (see screenshot below) you should be able to sync tasks and store maps in the cloud using a free account. There's currently no way to upgrade your free 'tasks account' to a paid version which also allows the creation of projects and subfolders.
Lets hope that the next months some clarification comes to us on what to expect, what it can do, why the others were not good enough and all the common questions any customer like you may have.
Maybe Matthieu is right about the future, although there has not been an official announcement to the market audience about it. This means that anything can change at anytime until it's official.
I tried it two days ago. I installed Mindmanager 2018 in my laptop and I uploaded the map files to a folder in Onedrive. I could open the map in Mindmanager, and everything seemed to be going well. Then I made a shortcut to that map in the map tab. And closed Mindmanager.
But when I reopened Mindmanager, it crashed! I tried restarting Windows many times, but always Mindmanager crashed at open. The only solution was uninstalling Mindmanager.
What happened? What went wrong? I don't remember enabling MINDJET TASKS & FILES in the software options. Maybe that was the problem.
What I have to do to use the map files in Onedrive? Something I remember is that I installed the library at a folder in Onedrive. To be clear, I don't need the software installed in the cloud. I have it installed in my laptop. What I need is only to keep the map files and the library files in a cloud like Onedrive. And open and use it whenever, and anywhere I am.
This is an edited version of a reply to a similar question I posted two years ago. Please note that it applies specifically to Dropbox and doesn't cover syncing with Mindjet Tasks or mobile versions of MindManager, but might still be helpful.
Provided you have the space on your main desktop and laptop PCs you can do what I do - keep a Dropbox folder locally on each machine which is synced with the Dropbox cloud folder. Since the Dropbox folder on each computer is like any other local folder there is no compatibility problem with most software including MM - you save a file to the local folder and Dropbox automatically syncs it to the cloud.
It's sensible to have at synced local folders anyway as in effect they back up the cloud folder - and vice versa. You never know when you might not be able to access the cloud folder.
Hi Jorge, I'm not sure about this as I don't use Onedrive (even though I'm also an Office 365 subscriber). However I think it would work based on my reading of this comparison review of Dropbox, Google Drive and Onedrive: https://www.cloudwards.net/dropbox-vs-google-drive-vs-onedrive/
This review recommended Dropbox partly because it can sync only the changed portions of files without needing to sync the whole file, which made it sync faster once files were initially uploaded (incidentally while it recommended Dropbox a number of the comments were critical).
Anyway, assuming folder synching does work with Onedrive I'm not sure how much of an issue this is. I suggest you could try it first with by setting up a dummy local folder and subfolders and then synching that to the cloud via Onedrive. Try adding files to the folder locally from applications such as MindManager, resync and see what happens. Then synch the folder to your laptop, add and edit some files there and resync the whole folder again.
In my case I use my Dropbox folder as my main local folder, so all my programs save there by default. This way there are no compatibility problems as all they see and interact with is this local folder.
There is one disadvantage to this approach - in a worst case scenario somebody could steal your laptop and access or even delete all your files from it. This would then delete them from the cloud next time the laptop was synced. For this reason I also back up the whole Dropbox folder locally from time to time when I'm at home to an external drive.
