Of course, I choose "Use another account", because it shows the wrong ID.
Now sometimes it asks for the credentials and showing the correct ID for the account it tries to connect to, but mostly it mixes up the IDs and can't even remember the correct credentials for each account.
Windows 10 Pro / Win7 Pro
Microsoft Office 365 / Office 2019
The problem is, that we are also using vba macros to send or receive emails to either account and if Outlook can't handle 2 accounts, we may have to switch to another Email software.
