Outlook 2013 not showing emails older than aprox. 6months old in any folders

Question

I migrated a VP of our company to Office 365 and now he's not seeing emails in folders that there should be. The problem seems to affect all folders but only emails after about 6-12 months old.

Other "clues" I've found are:

• Emails can be seen from the Office 365 Outlook Web Access interface
• The folders in Outlook will show the proper count of emails [75]
• Outlook is pointed to an exchange server (Office 365)

I suspect it's some sort of "don't sync if older than X" type setting but I have no idea where that setting would be.

Answer 2

Go into email account setting and set your server from IMAP to POP. You may need help from your service provider. IMAP mirrors the service providers server and some service providers dump your emails after 2 weeks regardless of your setting. Hope this helps.
