It would be best to close outlook for mac, and then work on the pc version. As to why there may be so many emails showing in the PC inbox. If you were using the inbox to funnel messages from one account to another. That could be a reason. Or, outlook for pc may be markling all messages as new, where as outlook for mac isnt. The data files (OLM for Outlook 2011 and MBOX for Apple Mail) are different in all facets of their structure. Users have to rely upon unofficial tools to move from Outlook 2011 to Mac Mail, and most of those tools aren’t reliable. This brings us to major issue causing frustration today.
Hi Rich, Are you trying to import a.olm file from Outlook 2011 for Mac into Outlook 2016 for Windows? If this is the case, you will receive something like the following error: The file.olm is not an Outlook data file (.pst). This is the expected behavior as Microsoft Outlook for Windows does not support.olm data files. However, there are several methods that you can use to transfer data from Outlook for Mac to a Windows-based Outlook client. These methods require that you use Microsoft Exchange Server.

HiRegarding Mails you can take help online IMAP tools, for the address book stuff, you can prefer converting them to.vcf files. Outlook windows does support vcf files. For the calendar, convert them to.icf files. Try these, only if you have enough time to deal with. My friend had tried this and it took almost 3 hours. I took help of OLM TO PST CONVERTER ULTIMATE tool by Gladwev. It transferred all my mails from mac outlook to windows in a max of 10 minutes.
Hope it helps. Mark it as answer, if it works for you Thank you.
