    Hi anonymous user

    In order to better troubleshoot the issue, would you please share some more information with us?

    For example:
    1.Does this issue affect all external and internal users? Or does it just happen on a few users?

    2.How many Exchange servers do you have in the environment? And what are the Exchange server versions(including CU version)?

    You may check it via Control Panel > Programs > Programs and Features.

    Here are some suggestions:
    1.Please run this command via Exchange Management Shell to locate the arbitration mailbox responsible for OAB generation:

    Get-Mailbox -Arbitration | where {$_.PersistedCapabilities -like "*OAB*"} | Format-List Name,ServerName

    2.Run the following command or restart "Microsoft Exchange Mailbox Assistant" service on the server to force OAB update:

    Get-OfflineAddressBook | Update-OfflineAddressBook

    3.Check via this path %ExchangeInstallPath%ClientAccess\OAB\<OAB GUID> on the server to see if the OAB folder is generated or updated

    4.Manually download OAB via Outlook again to see if the problem persists

    If you have multiple Exchange servers, please run this command via Exchange Management Shell to check if Global Web Distribution is enabled:

    Get-OfflineAddressBook | fl Name,GlobalWebDistributionEnabled,VirtualDirectories

    If GlobalWebDistributionEnabled shows false,please use this command to enable it:

    Get-OfflineAddressBook | Set-OfflineAddressBook -VirtualDirectories $null -GlobalWebDistributionEnabled $true

    Last Time we had changed the OAB Arbitration mailbox to another server and Database. we have update OAB using command Update-OfflineAddressBook <new OAB name>. command is successfully works and OAB working fine. After few days we are facing this issue and we have tried to update OAB by command Update-OfflineAddressBook <new OAB name> but OAB folder is not updated and OAB is not working as expected.
