I have Outlook 2010 at work, and I set up an email account at home using Outlook Express to be able to check my work email at home.
After the set up was done all my emails at work disappeared. How do I recover these?
Question: Is your work email still in Outlook Express at home?
It's likely you set up your home OE instance as a POP3 client, and OE's default is to download all emails into it's local .PST file.
If so, you can create a new .PST file in OE (at home), then move your work emails into it. Disconnect this .PST file, put a copy on a thumbdrive (or whatever), then connect that .PST file to Outlook at work. You may be able to copy the emails back into your work Inbox (there are circumstances where this is not allowed and/or not successful). Even if you cannot move the emails back, you'll still have access to them.
Here's the Outlook Express setting you missed:
(1) from OE's Tools menu, select Accounts
(2) select the Mail tab, then click on the email account in question
(3) click the Properties button on the right
(4) now click Advanced
(5) in the Delivery section at the bottom of this dialog box, click to leave a check mark on "Leave a copy of messages on server". I usually leave
not selected, and
