The connection to Microsoft Exchange is unavailable. RRS feed

  • Question

  • We are on Windows Small Business Server 2003 with Exchange, using Outlook 2010 on the desktops. I have a user who can no longer open Outlook - the error message 'The connection to MS Exchange is unavailable. Outlook must be online or connected to complete this action.' When I click OK it takes me to a place to verify the name, but it's unable to verify, even though the name matches the profile in Exchange/SBS. I've tried deleting the .ost files and re-opening, no luck. I've updated the Global in HKEY, no luck. I've tried uninstalling Outlook on her computer and re-installing, no luck.  I made sure all of the services were running, they were.  I removed her profile and re-added, no luck.  She can get her mail through Webmail, but just cannot open Outlook from her computer due to that error message.  All other users are able to open their Outlook from their desktop just fine.

    She used to be able to open and use Outlook, but now cannot, and (supposedly) nothing has been changed on the server or her desktop.

    What else can I try or do?

    Thank you!

  • Use Exchange Server ADUC.

    Right Click on the mailbx - Remove Exchange attributes.

    Then Run Cleanup agent.

    Then Reconnect the mailbox.

    iF you are doing it for the first time. please try for a test mailbox first

    -

    Make sure. your store doesn't have "Keep Delete Mailboxes Set to 0"

    If its 0 . As as you do it. It will delete the mailbox.

  • Users are not in ADUC, just the groups (ie Domain Users). The users individually are in Server Management, Internet and Email, Manage POP3 email.  Should I remove the e-mail from there and re-add?

    I suggest that you post in the SBS Forum, before you do anything.

  • Hi KristieF

    If other user are all well, perhaps the issue is from that particular user, How about having a look with below thread to check that user's PC client’s settings

    Also, I agree with Martina, you can post your issue on SBS Forum to get more help because your environment is SBS 2003

    Cheers
