Microsoft tools receive constant updates and are more future-proof than legacy programs
Standard programs such as Excel, Word and Outlook are part of daily work. They should be migrated as a priority.
Microsoft's diverse tools are often underestimated or unknown, despite their helpful capabilities.
Departments such as accounting or secretarial services are particularly dependent on functioning spreadsheets in Excel.
Department-specific requirements should be handled cohesively, so one is not overwhelmed by constantly changing specifics.
Especially important as well as API files with special scripts should be secured as a precaution and checked for functionality after migration.
The 5 most common mistakes when migrating to Microsoft 365
1. Old and new systems are operated in parallel
Employees constantly need double user logon, which is often perceived as a nuisance. Old systems can often be replaced with new solutions from Microsoft.
2. Schedule cannot be realistically estimated
When setting a schedule, the first difficulties usually become apparent. Schedules do not always run best case and buffer times should be planned for contingencies.
3. The order of the individual steps is not observed
The migration starts with a clean setup of the tenant. Many migrations start randomly and data loss occurs. Even small errors can have major consequences.
4. Obtaining a data overview
In order to be able to determine after the migration whether data losses are present, one should compile a data overview beforehand
5. Employees are not trained for new system
Employees should be informed about the migration. Employees should also be made aware of important new features. This is the only way to prevent major teething problems.

Do you know these problems? If you do, Microsoft 365 helps you out!
Office version differences lead to problems
Employees complain that files don't work as they should, or document sharing results in view errors.
Overview of user licenses incomplete, outdated or not available at all
License purchases are years behind and are assigned in a confusing manner. With the Microsoft 365 Admincenter you have the complete system clearly displayed, with variable license management.
Employees don't like to switch to a new system every few years
Many new features with major version jumps every few years can be disruptive for clarity and productivity. With the automatically updating system, the changes are mostly small and happen piece by piece.
Microsoft 365 to replace your on-premises Exchange Server
Exchange Server 2013 will reach its end of life support on April 11, 2023. The migration from Exchange 2013 to Microsoft 365 or Exchange 2019 is therefore imminent and should be planned now. If you do not migrate your Exchange Server in time, you are taking a high security risk. After the support end date, Microsoft shuts down its security services for the servers. Since the support end date is public, hackers can react promptly.

Microsoft Copilot
Microsoft is launching its own artificial intelligence co-developed by OpenAI. This is to be integrated into the various Microsoft 365 Office applications. This chat-based solution will not only provide answers in text form like ChatGPT. In several announcement videos you can see how Microsoft Copilot can summarize teams meetings for you to filter out the main points even after long meetings. In Excel, meaningful evaluations are created and data is structured. A PowerPoint slide of pure content becomes a vivid presentation with structure and consistent transitions. Copilot is able to learn from existing Word templates and apply this pattern to new documents to generate similar content.
These things and many more should be done in no time with Microsoft Copilot. The future will show how this solution can be integrated into everyday work. Already today, many people are using ChatGPT to work in a more time-efficient way.
Microsoft Kaizala
Microsoft will retire the Kaizala app on August 31, 2023. This collaboration tool was established in 2017 for Microsoft 365. Teams, however, has made this solution obsolete and has now completely replaced it.
October 10, 2023 - access support will be terminated
Office 2016 and Office 2019 are no longer supported when connecting to Microsoft 365. These versions can still connect to Microsoft 365, but their connections are no longer supported and you may experience performance or reliability issues in the future.
Windows Mail & Calendar will be replaced
Microsoft has announced that its standard "Mail" and "Calendar" software will be gradually replaced by the "Outlook" application from August 2023. The changeover is being made with the aim of offering users an improved and more comprehensive platform for communication and time management.
From August 2023, users will be able to migrate from "Mail" and "Calendar" to the latest version of "Outlook". This will ensure a seamless migration of emails, calendar entries and contacts. However, the switch will not be forced, and users will have the option to revert to the previous applications if they prefer.
Microsoft has already announced the end of support for "Mail" and "Calendar" at the end of 2024. From that point on, no further updates or security patches will be made available for these applications. Starting in 2024, new computers will also be shipped with "Outlook" instead of "Mail" and "Calendar." This change is intended to ensure that users are using the best possible software for their communication and time management needs right from the start.
