Hi,
I am facing some challenges the past 2 days that my apple mail applications closed automatically and display error message. I have to restart the applications and twice, I have to restart the machine.
Can someone advise me on what happen and how to fix it?
Note: I can't open a contract document from the email I received, or save it into my Laptop.
Thanks.

Hello !
As you are facing an issue that mail app is quitting automatically and you can't open a document when mail is received .
Please follow the article : OS X Yosemite: If an app freezes or quits unexpectedly
I will try to answer the second part of your question why documents are not saved when you receive mail , in your post .
Thanks !
Second part answer for your question :
Move the pointer over the message header click the Attachment button 
, choose Save All or click the name of an attachment, then select where to save the files. Or choose File > Save Attachments.
Drag an attachment to the desktop to save it there.
By default, attachments are saved in the Downloads folder, available in the Dock. You can specify a different default folder if you want: choose Mail > Preferences, click General, then select a folder.
Mail Apps auto closure
