If you are replying to a message, there is an option to skip the original parts that are marked with "> " but you probably already know that. When forwarding that is not an option because those markers are not inserted.

If you are not already doing so, might I suggest that you start to "snip" messages that you reply to or forward? This means taking the time to edit out any parts of the original which are no longer relevant to the current conversation. This might include headers with mail addresses and earlier messages in the thread history. This would leave far less for the spellchecker to stall on.

Many people don't edit their messages like this but it is the way it used to be done "back in the day", before the internet was mainstream and when a large e-mail took a while to download. Shorter message = smaller file size = faster transfer.

Perhaps you should turn off the automatic spellchecking and only use it manually on messages that aren't going to cause this issue.

Anyway, after all that, you may have gathered that the answer to your question is "no". Sorry.

I get quite a few e-mails from people whos first language is not English, and end up with e-mail threads pages long. When spell checking during send is it possible to skip checking the forwarded sections of the e-mail. Sometimes it seems like it takes 5 min. to "skip" all the non english and misspelled words in the chain, not to mention all the embedded e-mail addresses.

Thanks
