Outlook 2016 For Mac Counts Wrong

I’ve added week numbers to my Calendar but they don’t seem to match with my desk calendar which I believe is correct.

How can this be and how can I correct this?

There are several week numbering systems in use for the normal (Gregorian) calendar. The week numbering system of Outlook can be modified to match the week numbering system which is used by your country or region.

  1. We host a 2013 exchange for our client and emails and they have 2 users with Office 2016 We have setup an auto discover on their doman and their DNS (CNAME) pointing to our server but whenever we try setup the account it points to server.domain.co.uk (domain being their domain) and we are unable to change it.
  2. This issue occurs in Outlook 2016 for Mac version 15.9 and later versions when Outlook performs an Autodiscover operation and tries to connect to a service endpoint whose expected name is not present on the server's Secure Sockets Layer (SSL) certificate.

In Microsoft Outlook, you discover that the server count and offline item count for a particular folder do not match. The following screen shot illustrates this issue.

There are 2 settings that determine the week numbers that are listed in the calendar:

  • First day of week
  • First week of year

You can configure these settings by going to:

  • Outlook 2007
    Tools-> Options…-> button Calendar Options…
  • Outlook 2010 / 2013 / 2016 / 2019 / Office 365
    File-> section Options-> section Calendar

Verify that your “First day of week” and “First week of year” settings are correct.

Examples

If you live in the USA, Canada, Australia, New Zealand or the UK, you most likely need to set these options to:

  • First day of week: Sunday
  • First week of year: Starts on Jan 1

  • First day of week: Monday
  • First week of year: First 4-day week

Note: In the UK, as of 2004, according to the British Standards, the official first day of the week is Monday. Whether or not you should select the corresponding option depends on the level of acceptance of that standard in your sector/area.

Background info

The initial settings for Outlook are determined by the regional settings of your Windows version.

You can change your regional settings (language, location, date notation, etc…) in the Windows Control Panel or the “Time & Language” section of the Settings App in Windows 10. You can then use the settings in Outlook to overrule the week numbering system.

This method is useful when you are using a language of Windows that doesn’t match with the language of your regional settings. In those cases the names of the days will be translated to the language that is set in your regional settings, creating a mixed language environment which often is not desired.

Example:
Your Windows version is in English but by setting your Region and Language format to Dutch, the names of the days will be displayed in Dutch as well.

By setting the language to an English format (and possibly additionally changing the formatting options in Control Panel), you can maintain a fully English working environment and use the options in Outlook to match the week numbering system of your region.
