Keeping email records when moving between posts This question is about maintaining email records when changing institutions. I’m writing it here because it seems to be a problem quite specific to the academic context of managing long-term relationships within the context of a series of short-term posts which seems to typify post-doc life.

Now I’m in a new post-doc position, my student email has about 6 months left to run before everything is deleted when the account is closed, and which probably contains several thousand carefully filed emails (academic collaborations and correspondence, supervision and PhD project, university milestones, passwords, agreements...). Probably about only 30-40 of them will be crucial to me over the next couple of years, but it’s difficult to know which ones. I’d like to keep a fairly complete paper trail. I am also preparing to encounter this problem again when my post-doc post finishes in 18 months' time. 

A colleague who was in a similar fix ended up mailing hundreds of emails to her new account, which is clearly less than ideal. Another colleague just prints everything and stores it in paper files. If I wasn’t in academia I would switch emails to a more permanent one, but it is essential to use the proper address for work correspondence, so this doesn’t appear to be an option, unless if anyone has any ideas. 

(Technical bit: The previous system used Outlook and exchange on the web; the current system uses Outlook and outlook.com; the next system could use anything. To complicate things, Outlook has been auto-archiving files which means there are multiple .pst files, so this option looks a little nightmarish. I'm a mere social scientist, so eager to avoid a very technical solution.)

Has anybody found a reasonable system for handling this sort of problem, whether manual or automated, other than finding a permanent academic post?
You can use a permanent account while still having the emails sent to your official address.  I do this by getting gmail to check my university email accounts for me (Settings > Accounts > Check email from other accounts).  I am then able to reply to those emails directly in gmail, while having them appear to come from my university address (there is an option to always reply from the same address to which the email was sent).

I'm not sure whether this solution can be any use for the emails you have already received (you may be able to use it, if you can for example mark all your emails as unread, so that gmail maybe sees them as new), but it might be worth starting now to reduce future hassle.
