Emails in Outlook blank if open on Android device at same time

I posted this in the Office forum, but was told to try here.  I have a user who recently upgraded to Office 2013 and ever since then, he's had an interesting issue that I've never come across before.  When he opens an email on his Android device and then opens Outlook 2013, the email in Outlook is missing the body and attachments. If he already has Outlook open and then opens the email on his device, everything is fine.  If he has Outlook closed, opens the email on his Android device and then accesses webmail, the emails are fine as well.  It seems to only happen when the email is open on his mobile device and then opens Outlook afterwards.

Any ideas?  They're running on Exchange 2010 and he's already removed/re-added the Exchange account from his device as well as multiple other Android devices running different versions.  He's the only one that is running on Office 2013 and nobody else is having this issue on previous versions.

Thanks in advance for any assistance!
