Outlook

This question is answered This question is answered

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.
---------------------------
OK  
---------------------------

 

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?

Thanks,

otir

  • Hello Otir,

    From the description, the issue may be caused with the Outlook profile issue.

    Based on the current situation, please refer to the following steps to troubleshoot the issue.
    1. Check whether autodiscover service is working well with the Office 365 account’s suffix domain.
    2. Create a new mail profile for the Office 365 account.
    3. Connect Outlook 2010 to the Office 365 account in the new profile.
    If the auto-connection isn’t available, please refer to Method 3 in the Resolution section of the following article to manually configure Outlook 2010 to connect the mailbox hosts on Office 365.

    In addition, as for your concern, it is available to access the same Office 365 in Outlook 2010 on 2 different PCs. Nevertheless, it isn’t recommended.
