I'm having a strange problem with my email.

Years back I lost about year's worth of emails, and so I've been scrupulous since then about doing back ups.

Until about a year ago I simply saved them into various folders on a remote drive, until I noticed this strange problem.

What I find happening is that when I go into some particular folder all the emails in that folder will have been re-dated, That is, if there are a thousand emails in a particular folder, every single one of them will suddenly be dated, say 7-26-24, making it impossible to find something based on the date.

This doesn't happen all the time, but seemingly at random. I'll go into a folder I haven't searched in days, weeks, or months, and find that every single email--according to my computer--came in on the same date and at the exact same time. I have no idea why this happens, and there seems to be no reason why one folder gets screwed up, while another doesn't.

Since discovering this problem I've switched to saving the emails I want to save by converting them to PDFs, and so far there have been no problems doing that. But all my older emails are susceptible to this strange change.

Has anyone else encountered this? Is there something I can do, or stop doing, to keep this from happening?

What I do now is save everything on two separate drives, so that when a folder screws up on one drive I can copy over from another. But it's a definite pain in the ass to have to keep doing this.

I'm using Windows 10 with a Comcast account for email.

Anyone have any thoughts?

Thanks!
