    Hi @Mohammed Nadeem

    To narrow down this issue, I would like to first ask the following questions:
    1.Does this issue happen to all users or just some of them?
    2.Are the affected devices domain-joined or external?

    Please run the following command in Exchange Management Shell to get the server which hosts the OAB generation mailbox:

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

    Then check this path %ExchangeInstallPath%ClientAccess\OAB\<OAB GUID> on the server to see if the OAB folder exists.

    If the folder doesn't exist, run the following command in EMS to force the OAB to update:

    Get-OfflineAddressBook | Update-OfflineAddressBook

    Once the folder is created, please retry OAB download in Outlook.

    If the issue persists, please run a Test E-mail Autoconfiguration in Outlook and check the result under Results tag for OAB url.

    And run the following command and post the OAB settings:
    (Don't forget to hide your personal information in your post)

    Get-OfflineAddressBook | fl Name,GlobalWebDistributionEnabled,VirtualDirectories
