Outlook 2010 OST Issue with Shared Mailboxes RRS feed

  • Question

  • Hi All,

    We are facing an issue with Outlook 2010. More than 10 users are using one shared mailbox. They have created individual folders and subfolders in Inbox. The folders are not getting synchronised if cache mode is enabled. If we rebuild OST the mails will get updated. If we enable online mode it will work properly. Due to slowness we cannot work in online mode.

  • Hi,

    How did you add the shared mailbox in your Outlook? Did you add it via Account Settings > More Settings > Advanced tab > Add?

    It's no need to disable the entire Cached Exchange Mode, we can just disable caching of all shared folders to see if it helps. To do this, go to Account Settings > More Settings > Advanced tab, untick the checkbox before "Download shared folders".
