Old emails being re-sent when switching between Cached Mode and online mode


We run an Exchange 2007 platform with Outlook 2003 clients.  All users are setup in cached mode.  However on occasion we have to move them to online mode.  Also, when users access their emails remotely via Citrix, the Outlook session they connect to will be in online mode, so they do differ between the two.

We have found that sometimes when switching between modes, that users Outlook client will resend a bunch of completely random old emails (anything from 2 to10 mails we have experienced so far).

Would anyone be able to suggest why its doing this, and how I can prevent this from happening?

Are all users using laptops? Do they leave the office with their PCs in hand very often?

If not, is there any particular reason they are all on Cached Exchange Mode.

Best rule of thumb is: If the users are using desktops, and there are not any constant network connectivity issues.

Dont use Cached Exchange Mode.

Only use it if you absolutely need to.

Any particular reason for the "C" Grade?

Before giving a C grade you really need to have given the expert an opportunity to earn a better grade.

No one wants a C Grade.

If the above did not help, or if you had more questions you should have responded to the post and we could have looked into the issue more.

By not responding one can easily assume that the above did resolve, or help you to resolve your problem.

If it did resolve your problem or help you to resolve the problem the grade should be an "A" or "B"

If you still have the problem and the above was not helpful at all, or you do not want any further support on the question, or you have resolved it yourself, you should post the reason and or solution and request for the question to be deleted.
