I'm getting a 1025 error also

[Bobbi Robert]

We have a number of Macs in our office running Entourage
X, with all the current patches applied, and one of them
is getting a 1025 error when new mail comes in.

All the Macs get their mail from our Exchange 5.5 server,
and all have the same settings in Entourage, but only one
is getting this error.

I have uninstalled and reinstalled Office and rebuilt
Entourage, but the error persists.

I'd really appreciate any help I can get on this.

Thanks,
Bobbi Robert
