What IHM and Coyote say is correct, don't forward to personal account.
I work for Large International IT Co. and we use VPN (Cisco Client VPN)to enable emails from home, also firewall is mandatory.
OK, from my perspective.
Our corporate policy is don't do this. I set that. Here's why.
1. People forwarding emails to personal accounts killed our email gateways twice when emails were getting passed backwards and forwards.
2. When someone sends an enterprise an email, they expect it to stay in the enterprise. Passing it unprotected into the public domain is not what they expect to happen. Imagine if it got out into the public domain and was traced back to you?
3. If your personal device is not protected via a managed solution, if it gets stolen (and your personal security is poor), now someone has access to sensitive information. And that's your fault. Your company is liable and you are culpable. Guess who's getting sacked....
4. There's a reason that every single legal firm specialising in email litigation has gone out of business. Email over the internet is not secure.
5. Data protection does not apply outside the eu, and every large email provider hosts outside the eu. If you're recieving emails containing DPA related information, you're breaking the law.
6. Do you recieve data your company doesn't want outside it's boundary? Because most employees do. Oops.
Show some respect for your company policies. They're often not the IT team being arses, they're a result of a business driver being enforced by the IT team. If your company needs you to recieve emails at all times, they'll provide you with a managed mobile device, if they don't they won't.
Hope this helps.
I've been assured that there is a setting in MS Exchange to disable the ability for users to set up automatic forwarding to external addresses. So it may not be an option anyway. It is a bad idea though, as documented in plenty of detail in this thread.
I am also aware of someone who had an automatic forward set up, left the company they worked for, and continued to receive internal emails to their personal address for several months. So not all companies use the option or delete mailboxes when people leave...
Now, forgive me as I know stuff all about IT stuff but....
I can access my work e-mail on any device, personal or public using Cisco or something like that and Microsoft web app.. It is possible.
