Most of our MailShot users use it with the Mail app, so we are set up to work well with that by default.
However the iOS Outlook app does not accept names and addresses in the standard format of “name <address>,” when pasted into the address line (which you would do to forward an email to a group).
You can fix this by changing the format which Mailshot uses for names and addresses when they are copied to the clipboard.
Go to the Mailshot page of the Settings app (a shortcut is on the Settings button from the Support button in Mailshot), then disable the switches for “include names” and “use <>”, and enable the “; as separator” switch.
Now groups copied to the clipboard can be pasted into the address line of your forwarded emails in Outlook.
