Because the office interface and functional modules of OA system of each OA manufacturer are different, specific problems need to be analyzed.

Regarding the revocation of personalized signatures, I personally think that:

1. When sorting and submitting documents, there should be: Whether to apply personalized signature or not, just leave it unchecked.

2. If the document has been completed and the signature has been written, it cannot be revoked unless there is permission, or the oa administrator can assist in revocation.

3. If you want to cancel the personalized signature uploaded in the system, delete your personalized signature directly, or let the enterprise oa administrator delete it in the background or database.

If you can't solve this problem, you can contact the after-sales department of OA factory to help solve this problem.
