Added new IMAP account for the same email provider, deleted old account, re-selected in calendar settings.
Now sending invitations, either because
a) a new account was set up, OR
b) the POP (incoming) server settings caused a problem with sending invitations (unlikely?)
The POP settings were working prior to TB91.
Should this still be listed as a bug?
Thanks.
