(All the steps are: click the from box, select global address list, select purchasing. If we go through all of the steps to send an email from purchasing, using her account, it sends fine. If she sends from her own email, it works fine. If we log into it from OWA, it works fine. The issue is if she tries to send from purchasing, it get's stuck in the outbox. She also had send on behalf rights, but I recently removed them after reading about how having both can have issues. She has send as rights for the purchasing email account.
