So, I have had my Outlook email linked to several other software programs (tax software, Quickbooks) to send out communications from those programs. Recently, I had to change my password for Microsoft Exchange Office 365. When I go into those other programs and change the password to match, they refuse to send and say the password is wrong. I have copied and pasted, been EXACT with my input of the new password into those other programs and they insist the password is wrong. I have logged out of Outlook and back in, to make sure that I have the correct password and it works there, but not in the other programs. Help?
