Moving the Outlook OST file to another directory (Outlook 2010)
I would’ve thought this was already solved, but no. Moving Outlook data files is still ridiculously complex. And Outlook 2010 doesn’t seem to help it.
This page gives you nice instructions for the task, but could use some augmentation. Here goes:

First, where are Account settings in Outlook 2010? The answer lies behind the renewedly square Office button on your top left corner. Click that, and whoomp, you’re off to Outspace! There you have links to everything that used to reside in the Tools menu: Options, Account Settings, OOF assistant, Rules…) (click to enlarge the screenshot on the right).
Second, you may encounter the issue already familiar from Outlook 2003: What if the “Disable Offline Use” button is inactive? Well, the solution is simple: By following the instruction page linked from above, first disable Cached Exchange Mode on the Advanced Tab of the Data File Settings. Then click OK to close the dialog and open it again (via the Settings link). When you open the Advanced / Outlook Data File Settings sub-dialog again, the Disable Offline Use button should be enabled.
Third, when you have restarted Outlook after the Offline mode has been disabled and you have moved your files in Explorer, the Outlook Data File Settings dialog still has the File text box readonly, not allowing you to paste in the new OST path. But the Browse button next to it should be enabled, and you can paste the path there. You’d imagine the button is labeled as “Change…” and the filepath represented as a label if it’s not intended to be changed directly, huh?
The Outlook team should take a look at IE’s cache dialog (Tools / Internet Options / General / Browsing History / Settings). It has a very tidy “Move folder” button that handles all the ugly logistics. Yeah, it may require annoying logoffs and whatnot, but at least it does the job on my behalf.

The above article is very informative in the event of moving ost file. I just want to add here that if some how the Outlook ost file gets corrupted or becomes inaccessible anyhow convert ost to pst tools can convert the affected file into pst file which can be directly opened with MS outlook. Such tools are able to convert encrypted ost file to pst file

Sounds like this is a possible solution to a problem I have.
I want the best of both worlds; i.e. Corporate exchange server synced to local ost thru cached exchange mode. => everythings on the server for backup + available thru outlook web access + synced to WP7 phone + available in windows live mail local email client. Plus; I want outlook connector to sync to windows live hotmail (normally a separate, unmovable ost). All of the above particularly for calendars.
Then, if I accept a appointment invitation in outlook (exchange)it will show up in outlook web access and also in windows live hotmail calendar.
Question; If I use your method to "move" outlook to the connector ost — can cached exchane mode and outlook connector then share the connector ost?
i.e. "everthing everywhere".
Thanks

Never tried that, but I doubt it. The connector is unlikely to be fooled that easily :-) Let us know if you try it though!
