  • Hi,

    >>I have 10 pst file store on a local server location, my coworker have 12 pst stored on local server but he don't have this slow issue.

    Do you mean you store the PST files on a server side instead of the local client machine? The end users need to connect to the PST file saved in server side from Outlook 2010 in local machine.

    Generally, it is not recommended to store the PST file over the Network drive. There might be some performance issue if you do that. For more information about it, please read:

    If the PST file issue is saved in local machine instead of the shared network drive in your scenario, please confirm if you have opened all 10 PST files in Outlook 2010 and the PST file size is too large.

    Please try to remove all these PST files opened in Outlook. Create a new Outlook profile and open several PST files in new profile to have a try.

    Hi,

    What's your account type, Exchange account, IMAP or POP? In the new created Outlook Profile, please do not open all PST file, then confirm if you can send/receive new mails properly.

    Also go to webmail for this specific mailbox, confirm if the mail sending and receiving is correct or not. Make sure you have installed all updates for Office 2010.
