Email history

I am unable to find all my emails in my accounts. I have six of them. I have the IMAP settings to All Time with attachments but I only have about two months’ worth of emails whereas on some of the accounts they should be about five or ten years. I have tried the repair function but that does not seem to be working either. Please help.

As you have your IMAP accounts set to sync All Time but can only see 2 months emails, that usually points to your mailbox on the server end restriction.

What mail accounts are they ?

I have two accounts with Microsoft Outlook and four with Ionos servers. On my main office computer the emails are syncing for years.

Outlook, Ionos servers.

Are they all showing in eM Client on your main computer ? Or with a different mail client ?
