After Windows 8.1 released, users may encounter the issues about syncing files in SkyDrive. There are the error messages you may find:

1. Error 0xS00705B4: This operation returned because the timeout period expired
2. Sorry, the action couldn't be completed because the file hasn't finished uploading. Try again later
3. Error 80070490: element is not found.
4. Many SkyDrive folders in library like SkyDrive [1], SkyDrive [2]

We just would like to point out some possible causes of this issue and give you some suggestions to troubleshoot it.

Cause:

• Location was messed up during upgrade.
• Pending uploading or downloading task blocked in synchronization.
• SkyDrive was hang.
• GPO blocked the syncing behavior
• The user profile folder was relocated after upgrading.

How to fix:

Suggestions 1: Checking the consistence of locations on both registry key and SkyDrive properties:

• Right click SkyDrive -> Properties -> Location tab              
• Open regedit.exe, locate to the following key and check the location.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\SkyDrive

Suggestion 2: For many SkyDrive folders:

• Check which one can be explored properly with right files and relocate the SkyDrive folder via changing the settings in suggestion 1.
• Or create a new folder for relocating SkyDrives.

Suggestion 3: End the Skydrive.exe process and restart in command or disconnect and reconnect your MS account in SkyDrive to clear the pending task:

• Press Win+R to open run, and type following commands one by one:

%windir%\system32\skydrive.exe /shutdown

%windir%\system32\skydrive.exe

• Log off your MS account in SkyDrive and log in again to check the issue.

Suggestion 4: Check the GPO settings in both gpedit.msc and regedit.exe:

• In GPO: If User Configuration > Administrative Templates > Desktop -> Prohibit User from manually redirecting Profile Folders is enabled, please disable it. Dont forget to force update the policy changes: run command gpupdate /force as admin.
• In regedit: if DisablePersonalDirChange is set to 1 under HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer, please change it to 0 and start the SkyDrive to check the results.

At the end, we cant assure that these suggestions can fix all such issues. If you need further help, its ok to feedback here or submit a new thread with the SkyDrive.exe.err.**.log under C:\Users\[Your name]\AppData\Local\Microsoft\SkyDrive\logs uploaded for research.
