Crash when moving mails from Outlook.com to IMAP

Question

In my Outlook (Office 365, Version 1705 Build 8201.2102 Click and Go) I have set up multiple IMAP accounts and one Outlook.com ActiveSync account.

For some weeks now I have the following issue: When I move an email from my outlook.com inbox to an imap inbox outlook crashes. After this crash outlook crashes everytime I start it. The only temporary fix here is to remove the imap account I moved the mail to and recreate it in outlook. After this fix outlook freezes once but works afterwards.

Note: The email I moved like this is lost and is gone from the old inbox and nowhere to be found in the inbox I wanted to move it to.

Important: It seems to only happen with some mails. I sent me a short test email and could move it normally without issues. I then moved a normal mail I received and it happened again...

I also tried to start outlook in safe mode but it crashes anyway.

PS: Moving an email from IMAP to outlook.com works.

Thanks

EDIT info for IMAP accounts: Encryption is enabled SSL/TLS. Root folder path is set to: INBOX
