Saving Outlook messages

[mm5300]

Hi, I'm new to the forum and hoping someone can help me with my question. I have technical job and I get many emails over time (going back many years) that have relevance every now. However, my company decided the were going to delete email that are before a certain date. I've looked around at ways to try to save these emails, but I can't seem to get one to work. From what I can tell, they've disabled exporting, personal folders, and if you try to move emails to a different account, it complains something not be able to access the server. These are helpful emails, but I'm sure I'm in the minority of the company that needs to keep these. There's a lot of emails so it's not practical to just forward them to another external email address. I was hoping to find a way to save them in a batch. Thanks for your time.
