Earlier this week attempted to send email with 4 small attachments - not accepted as being too large.
Since then whenever I Receive or Send an email message my system freezes and I get a red triangle waring to the effect that message is too large. Also advised to go to Settings but unclear as to what I should change there. I get this each time even with one line emails
message under red triangle reads
[Exchange Web Services]Sending email failed due to the following error: The message exceeds the maximum supported size., The message exceeds the maximum supported size.
