Repair Outlook Error – Automapping not working with shared mailbox For Free

One helpful feature in Exchange Online and on-premises Exchange Server is automapping. When you, the administrator, allow automapping, the shared mailbox shows up in the user’s Outlook program immediately. Once you provide all users in the mailbox with full access permissions, the shared mailbox is automatically mapped.

Nevertheless, there are situations when shared mailboxes in Outlook are incompatible with automapping. A scenario like this might occur for several reasons, including:

  • Within the company, the user’s role and rights were modified.
  • In a hybrid deployment, the mailbox is relocated to a different forest.
  • The mailbox either becomes unusable or orphaned.
  • Organizational or configurational adjustments.
  • The Outlook data file has errors (OST).

Let’s now examine how to fix Outlook’s automapping issue using a shared mailbox.

How to Fix the “Automapping Isn’t Working with Shared Mailboxes” Problem

You can attempt the following solutions and troubleshooting procedures to resolve the Outlook automapping issue with shared mailboxes:

#1: Verify & Redistribute All Access Rights.

You can try removing the user’s full permissions and adding them again if automapping isn’t functioning. This will assist you in fixing the problem. Here’s how to go about it:

Note: You should have administrator access in order to carry out this procedure.

  • Users and computers in the Active Directory should be able to open.
  • Go to the shared mailbox, where the user is granted full access.
  • Choose the user’s attributes.
  • Click the tab for attributes.
  • To access msExchDelegateListLink, scroll down. Every user will have complete access permissions, as you can see.

Note: If the user is absent from the list, this is the cause of the automapping problem.

  • Take away the full access rights now, and then add them back. You can utilize the following PowerShell commands for this:
  • Take out-MailboxPermission-MailboxIdentity-User “username”-FullAccess Right
  • ‘Mailbox’ as the identity and Add-MailboxPermission -User “username” -Automapping $true -InheritanceType All -AccessRight FullAccess
  • Automapping ought to function now.

#2: Examine the XML Configuration for AutoDiscovery

Outlook receives the related data via the Autodiscover XML when a mailbox is mapped to a profile. One possible cause of the automapping not functioning issue is an altered or inaccurate Autodiscover XML configuration.

Check the Autodiscover XML settings, then. Follow the steps below to do that:

  • Click the Microsoft Outlook icon while holding down the Ctrl key.
  • Choose Test Email Configuration from the list of available choices.
  • Next, find and choose the “Use Guessmart” and “Secure Guessmart Authentication” choices. Press Test.
  • View the test results in an XML file format when they are finished.
  • Specifically, search for the <SharedMailbox> or <AlternativeMailbox> tags. Use ADSI Edit to verify the msExchDelegateListLink/BL attribute if your mailbox isn’t mentioned in the tag.
  • If you can access your mailbox and its related attributes, you can get support from Microsoft.

#3: Turn off the caching of shared folder downloads

  • Another option is to attempt to prevent shared folder downloads. Follow the steps below to do that:
  • Navigate to File > Account Settings > Account Settings in Outlook.
  • Navigate to the Data Files tab and choose the Outlook OST data file with the shared mailbox setup.
  • Select the Advanced tab from the Settings menu.
  • Click the “Download shared folders” option, then click OK.
  • Restart Outlook.

  • Select Remove > OK.
  • Now, rejoin the mailbox by doing the following actions:
  • Navigate to Account Preferences > Grant Access.
  • After selecting Add, click OK.
  • If any setup adjustments need to be made, go to Delegate Permissions.
  • On Shared Mailbox, do a right-click.
