Outlook 2016 forms not work, cannot retrieve attachments

Error = Your forms cache is probably corrupt

I tried this reg edit

Outlook 2016:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Office\16.0\Outlook\Security

DWORD: DisableCustomFormItemScript

Value: 0 (to enable)

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Office\16.0\Outlook\Forms\TrustedFormScriptList

REG_SZ: IPM.Note.AfterMail 

 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\16.0\Outlook\Security

DWORD: DisableCustomFormItemScript

Value: 0 (to enable)

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\16.0\Outlook\Forms\TrustedFormScriptList

REG_SZ: IPM.Note.AfterMail 

Value: (leave blank)

Any ideas?

  • Hello Ekelley,

    There are a number of reason that this issue could occur. 

    The most likely issue is the forms have not been enabled using our forms activation tool. This is a requirement after a Microsoft Update last year.

    You can find the tool at https://support.quest.com/metalogix-archive-manager-for-exchange/8.1.1/download-new-releases listed under Utilities.

    The EXE is for 1 off installations, the MSI is if you wish to deploy to multiple users with GPO or something similar. 

    If this does not resolve your issue please open a support case. 

    Thank you,

    Mark Hartley

  • Outlook has a number of built-in filters that you can use to search for messages with one or two clicks. The simplest way to display Outlook's search tools is to click in the Search Current Mailbox box at the top of the message list. Once you place your cursor in that box, the ribbon will display the Search Tools options.

    To find all messages with attachments, select the Has Attachments button. By default, this searches the current mailbox and sorts the results by date with the most recent on top.

    Greetings,
