Wrong week number in Outlook
Yes, you can set week numbering in Outlook:
- go to file - options
- in the left column select "Calendar"
- in the "work time" group there is a field "first week of year", here select "First 4-day week" (this is actually a synonym of the ISO definition)
Outlook uses whatever you set in its calendar options. The default setting is sometimes wrong and does not necessarily correlate with your Windows region settings.
