Normally I use multiple PCs from different locations. I tried to install Office 365 and Microsoft Office 2010 Professional Plus on a second PC and everything was successful. For connecting Outlook to Exchange Online, however, I was reported that manual instructions were required. I manually added the account on Exchange Online successfully. When I started Outlook, however, I receive the following message:

Outlook Data File
The file C:\Documents and Settings\*********\Local Settings\Application Data\Microsoft\Outlook\**********@*******.***.ost cannot be accessed because it has been configured for use with a different mailbox.


What was wrong? How could I remedy?

It is not allowed to access the same account on Exchange Online from multiple Outlook installed on different PC?
