Useful tips about Microsoft Office – Office 365
Outlook won't start or keeps freezing? Emails and calendar not syncing between your PC and phone? Constant password prompts interrupting your workflow? We'll show you the most common causes and solutions for add-in conflicts, corrupted OST files, and security settings.
Duplicate entries in your Excel lists? This distorts your data. Our tutorial shows you, using a practical example, how to clean up your data in seconds with the "Remove Duplicates" function – whether you want to delete identical rows or just values in a column.
The OFFSET function in Excel creates a flexible reference. Instead of fixing =SUM(B5:B7), the function finds the range itself, e.g., for the "last 3 months". Ideal for dynamic charts or dashboards that grow automatically.
The INDIRECT function in Excel converts text into a real reference. Instead of manually typing =January!E10, use =INDIRECT(A2 & "!E10"), where A2 contains 'January'. This allows you to easily create dynamic summaries for multiple worksheets.
Copilot is growing up: Microsoft's AI is no longer an assistant, but a proactive agent. With "Vision," it sees your Windows desktop; in M365, it analyzes data as a "Researcher"; and in GitHub, it autonomously corrects code. The biggest update yet.
Everyone was waiting for Windows 12 in October 2025, but it didn't arrive. Instead, Microsoft is focusing on Windows 11 25H2 and "Copilot+ PC" features. We'll explain: Is Windows 12 canceled, postponed, or is it already available as an AI update for Windows 11?
Want to block unwanted websites in Windows? You can do it without extra software using the hosts file. We'll show you how to edit the file as an administrator and redirect domains like example.de to 127.0.0.1. This will block them immediately in all browsers.
Caught red-handed? Your Outlook inbox has 1000+ emails? That's pure stress. Stop the email deluge with the "Zero Inbox" method. We'll show you how to clean up your inbox and regain control using Quick Steps and rules.
Deceptively authentic emails from your bank, DHL, or PayPal? That's phishing! Data theft and viruses are a daily threat. We'll show you 5 simple rules (2FA, password managers, etc.) to protect yourself immediately and effectively and help you spot scammers.
