The company I work for just migrated us all over to Office 365 for Outlook. We're told that at some point in the future, they are going to disable the ability to move message (sent or received) into pst files. All messages will remain on the Exchange server for a period of time (they are saying 2 years). I have always saved my all my messages and am concerned about losing long term access. Is there an automated way that could send a copy of all sent and received emails to another email address? I'm not knowledgeable enough to know how to write a macro or other routine to do this myself. Any thoughts or help would be appreciated.
If they are blocking pst files, they will likely block automated forwarding. For sent items, you'ds need to use a macro to BCC your other address - you can use rules for all incoming messages, but they can block that. (It is usually deemed a security risk to store mail outside of the company mailbox to avoid issues with eDiscovery.)
You should be able to create a folder and set a user policy to never delete to use for really, really important mail - but they might also remove that capability.
It's possible they will implement online archiving - in which case all mail is moved from your mailbox to the online archive linked to your mailbox. (The default for this is 2 years) If so, you won't have to worry.
