Good morning, everyone,

My Microsoft Outlook (Mac) has started to inform me that "Mail could not be received at this time."  The rest of the  message runs thus:

"The server for account Gmail returned the error '[ALERT] Too many simultaneous connections [Failure]" Your username/password or security settings may be incorrect. Would you like to try re-entering your password?   NO YES

I try to re-enter, but the message keeps returning ad nauseam. Same happens if I click NO.

I should add that I have another email account operating simultaneously. But it's been like that for years, and no problem until the past week or so.

Can anybody help? Please

Pat
