Outlook 2013 and outlook.com does not sync some emails and some attachments

When importing emails from an outlook.com email address to Outlook 2013 using the default setup I have the following problems:

All my emails in outlook.com have attachments, some emails show up in Outlook 2013 without attachments.
This happens in bulk and the bulks are not static, this seems to point to some sort of glitch/ overload problem in the syncing process. To troubleshoot I've deleted my .OST-file a few times and re-synced and different emails then have missing attachments. I also excluded the folder with the OST-files from Antivirus Scanning and still have large bulks with missing attachments.

Together with this problem comes another one.

Some emails in outlook.com are marked as "read" and some of the "read" messages does not sync at all, they remain in outlook.com and does not show in Outlook 2013. I see no obvious pattern here. Some "read" emails show up in Outlook 2013.

I've reconfigured the outlook.com account in Outlook 2013 and as mentioned I've deleted the OST-file a few times. This gave me different but similar results when it comes to the attachments. The missing emails are always the same.

This all seems to point toward:
the implementation of the default sync between Outlook 2013 and outlook.com not working as it should. This default sync method is EAS - Exchange Active Sync.

Have you worked around this? What helped in the end?

cheers

If you have an OST file, you are working with an Exchange account hosted by Microsoft.  That would indicate you have a paid plan with either MS Office 365 or another web host such as GoDaddy.  Either way you should have tech support to work with you on this problem.  I would start with them.

It is also worth noting that some attachment file types are not allowed by outlook but may be allowed in general from the hosted email.   These attachments will not show up in outlook at all as they are forbidden.

I have one OST for the Office 365 account and one OST for the Outlook.com account to which I'm connected through Exchange Active Sync.
