Hello team,

              Greetings. I appreciate your timely support to resolve the following issue with Outlook:

Issue Description :

When I tried to open a new mail in an expanded window, the dialog box displays the message ' could not install the custom actions outlook, The object could not be found'. I did try a few workarounds to delete the Forms tab and restart the outlook , however it was not working.

Office version : 16.

Windows version: 10 Enterprise

Thanks,

Vineeth

    Hi @Vineeth ,

    I did try a few workarounds to delete the Forms tab and restart the outlook , however it was not working.

    Did you clear the forms cache in Outlook? (File> Options > Advanced > Custom Forms > Clear Cache)

    If that doesn't work, try renaming the FRMCACHE.DAT to FRMCACHE.OLD and check if this helps, when you restart Outlook, and use a form Outlook will automatically reinstall the form.

    The location of this file is: C:\Users\User Name\AppData\Local\Microsoft\FORMS

    Besides, I would suggest you create a new profile and verify the results.
