I'm having synchronization problems after moving folders by dragging Reorganizing folders in Outlook via drag-and-drop can cause synchronization issues in Google Apps Sync.If you moved folders in this way and now some of your data isn't syncing, create a new profile and data should start syncing properly again.

The Google Apps Sync icon in the Windows system tray is showing up as offline Either your network connection is down, or Outlook might have switched into offline mode, for example, after a password reset.

I'm getting sync errors, or synchronization has stopped altogether Did you select an Unlimited mailbox size limit in Google Apps Sync?

If so your local PST file might have reached its maximum size allowed by Outlook (20GB by default), which can cause errors or prevent Google Apps Sync from syncing with Google Apps at all.

You'll need to either limit the mailbox size in Google Apps Sync (see Set a local mailbox size) or follow these instructions from Microsoft to change the size limit of your PST file and store more than 20GB locally.

It stores the rest (up to 25 GB) in the cloud, where it's accessible from the Gmail interface.

If you want more messages stored locally, you can increase your Mailbox Size Limit, say, to 2GB.

However, this isn't normally recommended as it can have an adverse effect on performance.

There's only one copy of the message, however, so deleting it from one folder deletes it from the other folders, too.

Executable file attachments aren't appearing anywhere Google Apps doesn't allow sending or receiving executable (.exe) and some other types of file attachments.
