We had an activity with five members, when sending notification mails
to all the members of this activity the mailing was split in two.

One mail for three members and one for the other two.

The thing that then occurred with the members of that activity was that
they didn’t saw everybody in the “To:” field and started mailing everybody
who was not in the “To:” field.

Raised an PMR at IBM for this one and got a very logical answer for it .

In the QA_MEMBERPROFILE table of the OPNACT database for Activities you will
find a column Locale, this one holds the locale you last used in your browser
to visit the Activities page.

When a notification mail is sent to you it will be in the language set by that locale.

It explained for us why the mailing is split sometimes, some of our have
a Dutch browser, NL, and some use an EN version of their browser.

Not that it’s a solution for the “problem” we got, but eh we have a explanation for this .

UPDATE

Came across this post on the Lotus Connections forum, it describes how
to force a language for Lotus Connections.

This way everybody will use  the same language and so everybody will
receive the same mail for  the notification.

Et viola, issue solved
