  • Hi,

    Do you mean when users click the shared mailbox folders, there will be an alert "The set of folders cannot be opened. The attempt to log on to Microsoft Exchange has failed."?

    Do all user mailboxes work well with Outlook?

    How do these users add the shared mailbox? Or the shared mailbox is set to "AutoMapping" when grant full access permission?

    Can users with full access permission open the shared mailbox from OWA?

    1.  If users use Outlook cached mode, please check with Outlook online mode.

    2.  Try to create a new Outlook profile.

    3.  Try to grant full access of the shared mailbox to a test user, and check if the test user has the same issue:

    Add-MailboxPermission -Identity <shared mailbox> -User <user name> -AccessRights FullAccess -InheritanceType All

    4.  Remove the full access permission of the shared mailbox and regrant without AutoMapping:

    Add-MailboxPermission -Identity <shared mailbox> -User <user name> -AccessRights FullAccess -InheritanceType All -AutoMapping $false

    Then try to add shared mailbox manually from Outlook. File > Account Settings > Account Settings > Change Account > More Settings > Advanced > Add the shared mailbox as an additional mailbox:
