Just what the title indicates, is there an upper limit on the number of concurrent sessions for a Gmail user?
1 Answer
Gmail support indicates that it currently has a limit of 15 simultaneous IMAP connections per account.
According to the Gmail Terms of Use, each user account is intended for single use. This means that if you have multiple users frequently accessing the same account or more than one IMAP1 client accessing Gmail at the same time, you may reach a connection threshold and receive the error message, 'Too many simultaneous connections.'

Hope that helps.
