I am out on site helping a local charity that is having an email problem.

They have a gmail account but it does not end in gmail.com, it has their own domain suffix.

They have one computer using Outlook 2010 to access the email, and another one that uses a web browser.

Last week they thought their email was being hacked so they changed the password. It wasnt being hacked by the way.

Now they cant access the email via Outlook (web is OK), even though they have updated the credentials in Outlook.

I have re-entered the credentials in Outlook several times now but it resolutely refuses to work.

What could we be missing?

EDIT : they are using POP. I know I could change to IMAP, but if all that has changed is the password why would POP stop working?

These are not people who adapt to change very well so would rather not do anything too drastic.
