Outlook 2013 .ost on multiple computers cannot access...

OK; I'll open with this is a hack, but worked well in the past.

Using Outlook and and an IMAP account, in the past was able to keep the .pst in a Dropbox account and with care in closing when not in use, we could open on a laptop and gain access to the account and then later same on workstation.  Was a simple matter of keeping the .pst file synched and all was well; never an issue.

Now years later trying to do the same with Outlook 2013, but its creating an .ost file for the IMAP account and not a .pst. , with the added grief of absolute not being able to move the .ost when its created.  So created a symlink on the workstation and that went well, the "real" .ost is now in the synched folder.

But, the laptop is being obstinate and will not connect to the .ost, claiming that it "...has been configured for use with a different mailbox."

Would be great if I could get this same old solution working again.  Worked so well in the past; question is how to overcome the complaint and get the laptop to use the synched .ost file?

Yes, I read that one.  The symlink solution I noted in the original question was the best solution I could come up with for the location of the file to dropbox on the workstation.

The issue is when setting the symlink on the laptop and attempting to connect Outlook with the exact same profile and email account as the workstation, Outlook rebels and claims the account is configured to a different mail box.  Not true, but what to do?
In fact when using IMAP account you don't need to share the account files, because that file reflect only the emails on server. What you need to share is the pst file where you archive the emails and to configure all clients to put sent emails on a Inbox folders.  
Of course it works better with Exchange server, but...

Hi, Dan...

I'll admit I haven't spent much time on this since I posted in.  Just assumed I was out of luck, but you've confirmed that .pst is where I need to get to.

If you could, the last piece would be how to use good old .pst with an IMAP, vs. the dreaded .ost?  Am I missing something that would create a .pst vs. a .ost?  I can use POP if that makes the difference.  

What I value in the synch. of .pst is calendar, tasks, etc. that are essentially local to the computer.  At this point, the solution is just for me; as you've written, others can use the server.  Thanks & regards...
In fact yes using POP is more easy.
The reason to use IMAP is to not download all emails from server, but the calendat and task can't be sync wyth the server. You can do it for the send emails if you manage to include the sent folders in inbox, but this because the sent emails are emails.
So if you use your account as POP3 account you should forget that problem of Ost file (in fact the OST file is a "cache"file where outlook put also the task and calendars.
