TB has worked fine until yesterday when I needed to send a message to more than 100. I split the address book into pieces and sent about 50 when TT502 came up.

I am using TB 31.7.0, Windows 7 PC. Have had no problems up to this. I split the 100 addresses into groups of about 20 and sent to 3 groups. The 4th did not go and I got the message: 'Too Many Recipients, TT502'. I cut the number of addresses down but the problem persists. I cannot send any messages now, even to a single recipient. So I have a problem that does not reset when TB is switched off and rebooted. Incoming is fine but I cannot reply. Any ideas?

Sounds like you hit the send limit of your provider. Obviously sending to 1 person is not too many unless your provider has an hourly or daily limit and has cut you off. Since the error has a server code associated with it the error came from your providers server. Thunderbird would not have anything to do with this.
