Outlook won't start with the newest update 16.15 (180611)

This the English version:
<br />
It's based on the channel and build. "Coming soon" is rolling out as a permanent change - if you have the navigation bar on the left and don't have the button, it was changed on your install and you won't have the ability to turn it off.
<br />In my test systems on the current channel (Version 2208 Build15601.20148), some have the Coming soon button, some no longer do.
<br />If you turn on "Try the new experience" in Word or Excel (click the megaphone icon on the top right), you'll have the new title bar and ribbon in Outlook.
<br />


<br />The What's New button should be live in all builds - It should also be on the Help menu. I've seen it disabled if there are no new things to report. Do you have Connected Experiences turned off in File > Account Settings > Manage Settings button under Privacy heading? That could affect What's new not showing content.
<br />"Try the New Outlook" is in the Beta channel - it might be in "Current Channel (Preview)", I need to update one of my test systems to the preview channel to check. It is not in Current Channel.

Hello

I am , Independent Advisor, to work with you on this issue. You should create a new notebook in Onenote online and copy the sections there from these .one files (on a Windows computer). Then you can access these onenotes from your Mac also

.

if I could - instead of installing Win 10 and OneNote 2016 - just subscribe to Microsoft 365 to get access to my old OneNote files on my MAC? - This won't work.

It simply won't work, because the button must not sit in the form wich is going to be edited.

Habe ich heute gemacht - warte auf eine entsprechende Antwort:

"I am Admin and I can insert any (existing!) folders in the field "Default local file location" and "Default personal templates location" (File – Options – Save), but the new folder will not be saved. If I reopen Excel, than the old standard
folder (user\xyz\documents) will be opened (File – Open – Browse, with the item File – Open – This PC all is ok). On all other Office 2016 applications (Word, PowerPoint, Visio, Project, Access) the new folder will be accepted also for the Browse item. I have
this problem with all my computers, even with a totally new installation of Windows 10 Pro 64Bit and Office 2016 32Bit in a totally new notebook. Can somebody help me?"

I was able to rename/delete the .ost file associated with the email account and once it rebuilt the problem was fixed. After closing Outlook, rename the file.

As an example: *** Die E-Mail-Adresse wurde aus Datenschutzgründen entfernt. *** => rename that file to *** Die E-Mail-Adresse wurde aus Datenschutzgründen entfernt. ***.

Restart Outlook and it will make a new file with *** Die E-Mail-Adresse wurde aus Datenschutzgründen entfernt. ***

The respective file can be found in : C:\user\username\AppData\Local\Microsoft\Outlook
