A new Exchange Server version was already announced at Ignite in Orlando, but Office will also be available in a new version in 2018. new version available. In most cases, Office will be released even earlier than Exchange 2019. This means that a few major migration projects are likely to start next year.
Today, at Microsoft Ignite in Orlando, we announced Office 2019-the next perpetual update for Office. This release, scheduled for the second half of 2018, will include perpetual versions of the Office apps (including Word, Excel, PowerPoint, and Outlook) and servers (including Exchange, SharePoint, and Skype for Business). Previews of the new products will start shipping mid-year 2018.
If Microsoft continues to follow its current strategy, it will not be possible to migrate directly from Exchange 2010 to Exchange 2019. Supported Outlook versions are expected to be Outlook 2013, Outlook 2016 and Outlook 2019.
Exchange 2013 and Exchange 2016 can be migrated to Exchange 2019 without any detours. If you are still using Exchange 2010, you will have to perform an interim migration to Exchange 2016 or Exchange 2013 beforehand if you want to update to Exchange 2019.
However, it remains to be seen whether Outlook 2010 will still work with Exchange 2019 (it will probably not be supported). If there are no significant changes to MAPIoverHTTP, it could work. However, I wouldn't rely on this, because up to now the rule has always been "2 + VNext", which means "Two previous versions (Outlook 2013/2016 and the latest version (Outlook 2019).
I don't yet know which new features will make it into the next Exchange Server version. If anyone already has information, please leave it in the comments.
