How I fixed it:

I found the solution here:

• Confirm your search is working at all: Create a new user and check if search works. If it does, go on (with your old user where search does not work).
• Backup RegKey: Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Search
• Delete the whole Key (including all sub keys + values)
• Access the search (e.g. press windows key and try enter something)
• Nothing will happen. Try this a few times, when it starts working again the key has been recreated.
• Either import the backup or just use the new settings (which you may want to adjust)

How to change the display nome of outlook.com account / ost-file in folder pane in Outlook 2013/2016

My outlook 2016 was showing my outlook.com account using my microsoft account e-mail address. I was looking for a way how to rename the "blabla@outlook.com" to "Outlook.com-Account", like i can be done with POP/IMAP accounts.
But the properties of the data file only showed me the path to the .ost-file, but no Textbox to enter a Display name.

How i fixed it:

I found the solution a Microsoft answers forum, posted by Verdhaham Shetti:

Here's his solution, which worked for me:

"Let's follow the steps to change the mail box name for EAS account.

3. Once the windows screen has popped up....scroll down to your Printers/Faxes section.

4. Right click on the P2015 printer icon.

5. In the drop down menu, select "Printer Properties"

6. Once the Printer Properties dialog box has opened, click on the device settings tab.
