Exchange 2013: Secondary mailbox must be manually refreshed to get latest emails ?

    Question

  • Hi All,

    I'm using Exchange server 2013 SP1 and got this problem with normal mailbox being used as "shared" by several people at the same time.

    The mailbox is called Management Team, this mailbox is accessed by about 10 users across different locations.

    I've checked that all of them has been granted as Full Access users in their Outlook 2010-2013 and 2016.

    The problem is that the users can only see the email when they click on Refresh on the "Management Team" mailbox. otherwise, none of them see any emails are arriving.

    Their respective normal user inbox is working fine.

    1. Do I need to convert the User Mailbox into the Shared mailbox?
    2. How to safely perform user profile cleanup or recreate it without causing email or data loss?

    What could be the issue on this User mailbox and how to fix?

  • Changing mailbox permissions won't result in data loss unless the person to whom you grant permissions deletes data.

  • Quit doing cut and paste or do it from Notepad so that your question isn't imbedded with a whole bunch of HTML we can't read.

    Sorry, Ed, that was Google Chrome Plugins called Grammarly doing it.

    I've edited the original question.

    Have you granted folder rights or full access rights to the mailbox as an administrator?  Please be specific, and please tell us specifically how users are trying to open the mailbox.

    1.  That should not be necessary.

    2.  Profile changes shouldn't cause data loss.

  • Ed,

    After the users granted the full access permission like below:

    1. In the EAC, I navigate to Recipients > Mailboxes.
    2. Find the mailbox and then click Edit.
    3. On the properties page, click Mailbox Delegation and add the users manually on the Full Access section. 

    Usually, the mailbox will appears after few hours in their Outlook client.

  • Hi,

    Have you tried to run Outlook in online mode?

    You can try to remove full access permission then use the command below to add permission to them:

    Add-MailboxPermission -Identity JeroenC -User 'Mark Steele' -AccessRight FullAccess -InheritanceType All -Automapping $true

    From your last post, you said "mailbox will appears after few hours in their Outlook client." I think your issue is caused by a large network load in your environment.

    Usually, it just need a few minute, this mailbox will occur in other user's Outlook client, it need few hours in your environment, I think it related with your network load.

    Regards,

    Kyle Xu

  • OK, Do I have to convert the mailbox into Shared as the current mode is user mailbox?

  • As per this Technet document for Exchange 2010: https://technet.microsoft.com/en-us/library/hh529943(v=exchg.141).aspx

    The PowerShell script is:

    $FixAutoMapping = Get-MailboxPermission MySharedmailbox@domain.com |where {$_.AccessRights -eq "FullAccess" -and $_.IsInherited -eq $false}
    $FixAutoMapping | Remove-MailboxPermission
    $FixAutoMapping | ForEach {Add-MailboxPermission -Identity $_.Identity -User $_.User -AccessRights:FullAccess -AutoMapping $false} 

    Is it possible to run the script above with no data loss for the mailbox?

  • The remove and rebuild the Outlook profile is not working.

    I also have re-added the User permission and set the -AutoMapping $false.

    Both of the above is still not resolving the issue.

    The user still needs to manually refresh the shared mailbox to see any updates.
