Signature setting being lost

[gdf1903]

Good morning,

We have someone using Outlook 2003 with Exchange 2003. Outlook is
running in cached mode. Every few weeks the signature settings are
lost. The signature remains and can be selected, but if the user has
selected a particular signature for new messages, this has been lost.

I have removed and readded the signature, checked for any Outlook
errors, but it continues to occur.

Can anyone help here please?

Thanks.
