However I'm still getting the error.īecause Outlook won't allow the attachment, ShareFile isn't automatically kicking in, even if I lower it's threshold.Īny thoughts on why the registry entries aren't working?Ĭomputer\HKEY_CURRENT_USER\Software\Policies\Microsoft\office\16.0\outlook\Preferences\MaximumAttachmentSize=0Ĭomputer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Preferences\MaximumAttachmentSize=0 Online research led me to add a registry entry setting MaximumAttachmentSize (0 means unlimited) and I've added the entries. However, Oultook is not allowing the attachment of large files with the error "The file you're attaching is bigger than the server allows." However, the plug in triggers when they attach a large file. We use a third party service to send large files.

I'm attempting to remove the attachment size limit in Outlook 2016 (Office 365).
