Dear
Good day! You can set the date format across all Microsoft 365 platforms by changing the regional settings in your Microsoft account.
- Sign in to your Microsoft account.
- Click on your profile picture in the top right corner and select "My account".
- Under "Language and region", click on "Change language and region settings".
- Select your preferred region and language, and click "Save".
- Your date format will now be set to DD/MM/YYYY across all Microsoft 365 platforms.
Note that this will only affect your account and not other users in your organization. If you want to set the date format for all users in your organization, you can do so through the Microsoft 365 admin center.
Sincerely,
Tin
