Exact action taken:

- Open Outlook, Select 'New Email'

- Select 'Laserfiche' and 'Attach Laserfiche Document'

- Search for file, and attach as copy

2-5mb files are taking 30 seconds to 1 minute to attach.  15-25mb files are taking nearly 2 minutes

I did notice there is a difference in how large these files are depending on how they are being attached. 

For example, using the method above, the file will typically be 2x larger than if I were to drag the same document from Laserfiche into Outlook.  

The file is typically a TIFF, and when doing both methods, being  sent as a PDF.
