Hoping that someone can help with yet another calendar problem with Outlook
2007

Often, but not always, I open a single occurrence of a recurring event and
make a change to the contents, when I click 'save' I get the following
warning:

'The time of the meeting has changed. Choose one of the following: 'Save
changes and send updates' or 'Don't save changes'"

The problem is that I haven't changed the time of the meeting; in fact I
haven't changed anything except for adding some text.

It's very frustrating as not only have I not changed the time, but I don't
want to send unnecessary updates.
