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

This usually happens due to one of the following reasons:
- Insufficient permission on the SendMail folder
- The SendMail folder is corrupted
Solution
To resolve the problem, try the following steps:
-
-
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.)
-
Move the SendMail folder to Trash.
-
Now close Acrobat and relaunch it. (It'll re-create the SendMail folder, and that should fix the problem.)
