I have a problem with my Outlook. My mails are getting deleted after 3 months. I am not able to get back those if required. Because of this I am losing some important emails in Outlook. How can I get back these emails?

What version of Outlook are you using? Windows or Mac? When you right-click on > Data File Properties > Policy -- do you see any details about Retention Policy? This is assuming you have Office 365. – Sun Jun 1 at 21:03

Outlook has a function called 'auto archive'. You can use this to move 3 month old mails to an archive folder before they are deleted.

If this is already turned on and the archive folder is not connected in your list of mailboxes then this might also be what is causing your mails to go missing. In which case it will be easily rectified on most outlooks installs via 'file' 'open' outlook datafile' (browse to file). In Outlook 2012 seems to lack this option and forces you do to the same thing via the control panel.

I tried as per your sugession. But the file is containing empty. No mails are archived. :( – mdhar9e Jun 14 '12 at 13:24
@mdhar9e - They were not deleted. They were archived. Now if the archive file was deleted that is a seperate story. If you cannot find the archive file it means the emails are likely lost. I would suggest you request IT support at your company and ask how to prevent this from happening in the future. – Ramhound Jun 14 '12 at 13:46
Nods. if this in a company then ask your IT support. They may have a setting where they move old mail from the exchange server. There are performance and storage reasons to do this. If not I assume default outlook settings. I have no outlook next to me (at home atm), but I remember the 3 months as the default archive time in outlook 2003 and outlook 2007. – Hennes Jun 14 '12 at 15:59
Some bozo in IT can also set the Retention Policy to Delete after 90 days. With that kind of policy, your old emails are gone. – Sun Jun 1 at 20:58

I have a similar issue. Until a week ago, I could see emails I had saved in my Yahoo personal folders (after Yahoo upgraded) on my Windows 7 laptop dating back to more than a year. Unbeknownst to me, M.S. upgraded my desktop Windows 7 to Windows 10 a few days ago. Almost immediately, I saw that a lot (not all) of my Yahoo personal folders only had emails dating back to not more than 3 months. Fortunately, I found guidance in a blog that allowed me to change "3 months" to "any time". After making that change and synching my emails several times over the period of several hours, the 3 month finally restriction was eliminated and I can once again access my earlier saved emails. Here's the catch, once the issue with the desktop was resolved, I could no longer access the older emails on my laptop. I have no clue if the two are related and cannot find similar guidance for Windows 7.
