I am not sure where to start on this question.We have purchase orders on Excel. We open the PO and enter the info we want. Then we do the file, send, send as email attachment, option.This works just fine, but we have a workaround system using a MAPI email account through Outlook.com for synchronizing our calendars and contacts.This email is set as the default data file so that when we open the contact list and hit add new contact, that it automatically goes to this MAPI email account and synchronizes to the rest of our computers and BB's. The same is true for the calendar. When we open the calendar and want to add a new event the calendar that is automatically chosen for the new event is in the MAPI data file because it is default. This then is very smoothly synchronized across mulitple devices.Now the problem is this. We have two people always in the office. If we use this default data file as our default email address file, then both workers get each others emails (not a good scenario). So we hide this default data file as much in the background as possible and everything works great; until....When we open our PO's and want to send them as an attachment from Excel. The same holds true for documents from Word. Just before we send the email we can choose the option to send the email from the correct email address in the dropdown menu just below the send button on the 2007 outlook new email box. But when we hit send then it somehow jumps back to the default data (not default email) email address. So people end up getting emails from two different email addresses from the same person.How can I avoid or fix this?Anyone have a clue?
