  • Slow shared mailbox

    Hi,

    I'm running into an issue with shared mailboxes. The scenario is we've got an office in Europe and an office in the US linked by mpls. We have a shared mailbox that users both sides of the pond will use. When adding the mailbox in as an additional mailbox, the performance for the US is very poor, europe is OK, the mailbox is on the european server. From what I've read, the shared mailbox doesn't get cached by Outlook. If I create a profile with the shared box as the 'primary' and the personal as secondary, the performance is fine so it looks like this is correct, but this isn't an ideal solution.

    Has anyone else tried to do a shared mailbox across a WAN like this or any idea if it's possible to cache a secondary mailbox in Outlook. I've spent the last four hours trawling google and I appear to be the only person in world either trying or having problems with this!

    Any help will be greatly appreciated.

    Ta

    What sort of things do you use the mailbox for?
    Do you have public folders?

      It's a tech support/helpdesk. Public folders wouldn't be ideal, unless I'm missing something here, and it's possible. If someone replies to a message from it, it wouldn't use the address for the folder as the return address and sent items would be more problematic that they already are.

      I'm very open to advice on how to do this if anyone has experience on this sort of thing.

      Forgot to say, there are quite often reasonably big attachements too around 10mb or so

        Hmm.
        Do your US and EU sites not support different client bases anyway? Can you not have two?

        Can you not reduce the size of the mailbox maybe?

        Sure if this is relevant?

          The mailbox size is tiny, we're just testing it at the minute, and it's dissapointing before we've started!

          The helpdesk guys really need it to be consistant. The US office is west coast, so we get east cost stuff coming in from lunchtime onwards that needs to be dealt with straight away and the US guys will pick this up after the european office closes if it's an ongoing issue.

          I'd read that experts exchange post, it doesn't really apply, I tried what they said and it didn't make any difference. We're a mix of 03 and 07 still.

          Any other thoughts?

            There isn't really a lot you can do.

            You are pulling everything across the WAN link live, which is never very fast anyway - which is why cached mode was used.

            OWA or a Blackberry may be a better solution.

              This is what doesn't make sense to me. If I create a new profile for the shared box alone, it's fine speed wise, it's only when added as a secondary mailbox that the performance is poor, which must be because it doesn't cache it. I don't get why Outlook/Exchange will only allow you to cache one mailbox at a time. I appreciate it's going to be slow pulling any mail into it's inbox, but once it's in as I understand it only updates to the mail location needs to be sent back and forth to the server which should be quite quick

              There's no way to 'mount' a mailbox into a subfolder of another mailbox is there?

                Is the second mailbox slow every time you access it or only the first time?

                  It's a bit wierd actually, doesn't seem to matter whether it's the first, second or tenth access, but what is odd, if I move an email with an attachment to a subfolder it goes pretty quickly, move it from the subfolder back to the main inbox and it takes ages. Very odd!

                    The reason you cannot cache the mailbox locally is because it isn't "your" mailbox. You don't have control over it, that is the responsibility of the owner of the mailbox. It is to protect the mailbox from having multiple entries made in cached mode and getting a conflict on the sync.
