About 6 months ago I switched my GoDaddy email account from a POP to an IMAP email. Shortly after that I noticed that emails I knew I once had were mysteriously gone. I am a compulsive email saver...hardly delete anything....yet emails would suddenly not be in my inbox, my deleted folder, any of my other folders - nowhere. This was true both in Outlook and on the server through GoDaddy, since the two are set to match. Recently, after many little experiments, I have discovered that Outlook is deleting my emails from my inbox after 14 days. Deleting them without a trace anywhere. They don't go to my deleted items folder, they just vanish.
I have traced this problem specifically to Outlook (2007) because if I am away from my computer and check emails only from my iPhone, the emails older than 14 days stay in my inbox with no problem. I was just away for 2 weeks on vacation, and all the old emails remained. A minute after I had come home, started up my computer, and connected with outlook, the emails older than 14 days were missing. They are now also missing from my phone and web server (where they had been until opening outlook) because all three of these locations are in sync (the whole point of switching to IMAP).
Autoarchive is OFF, and there seem to be no settings anywhere that tell Outlook to delete messages older than 14 days. I have done extensive troubleshooting with the folks at GoDaddy but we have not been able to find a single setting that could be causing this. This doesn't happen to any of my other (POP or Exchange) email accounts, only this one. Help? It is obviously a major problem if Outlook is deleting messages on its own - I often have messages older than 14 days that need to be addressed and therefore are sitting in my inbox.
