Outlook unable to synchronize SharePoint library - error 0x80004005
- by DLux
We have one large library (~10 GB) on SharePoint that cannot be synchronized with Outlook, even if you only attempt to synch one of the smaller sub folders in the library. Other libraries (or other library sub folders) work fine with Outlook.
This is with MOSS 2007 SP1 and Outlook 2007 SP2.
The error is:
Task 'SharePoint' reported error (0x80004005): 'An error occurred either in Outlook or SharePoint. Contact the SharePoint site administrator.'
Reproducing the error
Open up the large SharePoint document library in Internet Explorer
From the Actions menu, select Connect to Outlook
Select Allow on the stssync: security warning that pops up
Outlook automatically tries an initial sync and sync status immediately shows the above error.
Update 1: I verified the same issue occurs on Windows XP SP3 with IE 6 using Outlook 2007 SP2 and the same SharePoint library (it was originally tested on Windows 7). The issue is definitely related to the library or Outlook.
Update 2: Using stsadm I exported the site with this large document library (8.6 GB 15,000 items) and imported it on to a development system. The result is the same on the development system - multiple clients are unable to connect Outlook to the library and get the 0x80004005 error above.
