imap e-mails from 2011 outlook did not transfer in migration from 2011 to outlook 2024 for mac

Question

Hello,

I have an old outlook for mac (office 2011) with lots of e-mails from my business i-map account (they are downloaded to my e-mail account and not on the server any more) that I need to migrate to outlook 2024 for mac. I exported the data on outlook 2011 in an olm file and then opened outlook 2024 in legacy mode and imported the olm file there. When I did this however only my hotmail and g-mail e-mails and folders were migrated but not my business i-map e-mails and folders?

I checked the firewall settings which is not on but as the files are not on the server any more that should not matter?!

What am I missing? I need to transfer those e-mails... Is there another setting that I need to adjust or is there another way to import all those e-mails?

Please help

Thanks,

Peter Strzebniok
