Accessing Additional Mailboxes In Outlook 2003 Offline

Posted on 2005-04-27
Last Modified: 2012-06-22

I've got a user who is running Windows XP professional and Office 2003 on his laptop.  Outlook 2003 is set up to access the company exchange server remotely via a VPN connection and he is able to download a copy of his e-mails onto his laptop as Outlook was set up to work in cache mode.

The user has said that when he opens up Outlook and works offline, he can access his primary mailbox without any problems.  He got another 3 additional mailboxes but when he tries to select these, he can not access them.  I've looked on the internet but can't seem to find anything that would allow him access to these mailboxes offline.

I guess I could set up a seperate profile for each of the 3 mailboxes but ideally, if it can be done, i'd rather have it set up so he can access all 4 mailboxes offline under the same profile.

Any help given would be greatly appreciated.

    No, the OST file creates an offline version of the mailbox associated with the profile, not any additional mailboxes that the user has permission to and accesses while online.  You cannot add additional OST files to a profile either.

    It would work if you were willing to set the default delivery point of the additional mailboxes to a PST file on the users laptop, then he could access them offline.

    Otherwise the seperate profile method you mentioned would work.  Other options:
    Use OWA to access the other mailboxes
    Configure POP3 on the other mailboxes, configure his profile with a PST file and a POP3 account for the other mailboxes with the option to leave a copy of the message on the server, then set up a rule which moves any email from the POP accounts to the PST file or files (you would have a seperate folder or even PST file for each account).

    Thanks Traval

    I explained to the user the alternative ways to access his additional mailboxes offline as stated by yourself but he decided to stay with the current set up for now.

    Thanks for your help on confirming that additional mailboxes can not be accessed offline under the current ost file and also stating ways round this problem so that they could be accessed if need be.

    Much appreciated for the help given
