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:

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.

• If you can access your mailbox and its related attributes, you can get support from Microsoft.
