Outlook email 365 password window popup

[Fordette]

Hi

I installed Office 365 outlook and we have switched to exchange for the emails

The old email account which we connected to microsoft emails was an IMAP account

The new one is exchange. 

I do not want to delete the IMAP account because I had some other folders under that account. 

When I open up outlook, the imap account because its no longer working, a message keeps popping up asking for username and password. If I try and remove the email account, the message that pops up says Careful if you remove this account its offline cached content will be deleted. I only want to stop the password box from popping up.

Thanks

Hi, there is no security tab on the IMAP account. There is a security tab on the Exchange account but the Always prompt for login credentials is already unticked.
