Acrobat crashes on clicking the attach to email icon

Acrobat crashes on clicking the attach to email icon | macOS Mojave 10.14

When you try to attach a PDF to email using the Attach to Email icon in Acrobat DC on macOS Mojave, Acrobat crashes with the following error message: “Acrobat Pro DC quit unexpectedly”.

This usually happens due to one of the following reasons:

Insufficient permission on the SendMail folder
The SendMail folder is corrupted

To resolve the problem, try the following steps:

From the menu bar on the desktop, click Go > Go to Folder.

In the Go to Folder dialog box, enter /private/var in the text field, and then click GO.

Using the search box at the upper right corner of the dialog box, search for "SendMail". (Ensure that you select the “Var” folder, else it may not find it.)
