3 users with a BB, BES is outside; with the provider.
Locally a Windows 2003 SBS server with Exchange.

1 users works fine; no problems at all.

2 users receive all emails, but can't send any emails. Sent emails appear in the drafts folder on the pc, not in sent Items.

Checked the settings (Send data, ...) in AD, all settings are equal to user A who's able to work.

Provider states all works fine for them. This morning user doens't even receive any emails anymore. Provider has called user; whiped his BB; send new activation; and should be ok now; receiving emails; Still not possible sending them.

Please help.

thanks
