on one user-mailbox at a customer I've following problem:

Signature with picture (incl. web-link) in it won't show pictures in just only 1 Mailbox if mail is sent after client startup.
Signature should be added automatically.

User have to go to tools -> options -> environment -> signature and changes the value from "automatically add" to "prompt bevore adding" and back to get it work normally.

Also it works great if "prompt bevore adding" is assigned at client startup.

Repair of Mailbox doen't help.
Reset of Client Options doesn't help.
Tried on other users mailboxes it works great.

System: GroupWise 8.0.2, Client 8.0.2

Any other ideas?

Thanks for help,
