Open-Xchange OXtender 2 issues with Outlook mail sync, some mails missing on the client

I use the Open-Xchange OXtender 2 to sync my groupware account with Outlook 2013  client at work.

The Open-Xchange Server Version is 7.2.2-Rev 14, The OXtender 2 Version is 7.0.64.2861 (32 bit). My OS is Windows 8 (64 bit) with Office 2013 (32 bit).

A few days ago i realized, that some mails in my server inbox did not appear in the Outlook inbox, but neither the mail content nor the OXtender logs gave me helpful information why it happened to this particular mails.

So i decided to "reset" the OXtender local cache as described here: (Be careful! All your local data is lost! Backup first in case not all the data is on the server!)

Use the SupportTool to re-create OXtender 2 MAPI services

I found the support tool on my computer here:
C:\Program Files (x86)\Open-Xchange\OXtender 2 for Microsoft Outlook\Profile

This is how it looks like:

After re-creating the service, the sync was working fine again.

 



 

Office 365, Outlook 2013: OpenXChange OXTender 2 MAPI Mail profile error "oxstor.dll" could not be loaded

Today i installed Office 365 in parallel to my existing Office 2010 on my Windows 8 Computer. Under Outlook 2010 i use OpenXChange OXTender 2 - Version 7.0.62 to sync with OpenXChange Groupware.
After installing Outlook i created a new mail profile. But in Outlook 2013 i can't open the MAPI Folder. Clicking on it an error message Pops up "The Folder could not be expanded.... MAPI was unable to load the Information service "oxstor.dll" ..."

I also re-installed OXTender, but this did not fix it. Under Outlook 2010 the sync is still working fine.

I posted the question here:

How-i-fixed-it:
The document Outlook OXtender 2 Best Practices states, that it does not work having both Office 2013 and 2013 installed in parallel:
...
Please note that the following is not supported:

• Office 2010 Home and Business test version
• MS Outlook running in a virtual environment (e.g. VMware or Parallels Desktop)
• Using both OL2007 and OL2013
• Using both OL2010 and OL2013

....

I removed Office 2010 from my Computer and re-installed Outlook OXTender again, created a new profile and... it works.
