Are you referring to the name of the calendar which can be shown after the event and task summary?
Yes, I am.
You can disable that from Options->advanced->Show task calendar (and Show event calendar).
Having installed the German language pack I can only guess that I'm looking for the right menu item and set the respective option.
There are 3 items in the "calendar" section of the "advanced" menu:
1. "Icons im Kalender zusammenführen" (join icons in the calendar)
Changes have no effect on what I see.
2. "Kalenderwahl per Mausrad" (choice of calendars by mouse wheel)
Also no visible effect.
3. "Aufgabenkalender anzeigen" (show task calendar)
Nothing to see, again.
The latter is certainly what you refer to. As I have only the Outlook calendar in use I cannot test whether another one would be hidden upon changes here. But this is not at all the problem I'm talking about:
As you can see in the attached screenshot Outlook's name
is visible - unnecessarily. My suggestion was to inhibit the display of this name
only, not the whole calendar.
Thank you very much for your answer.
