Outlook e-mail and calendar stops alone

[Jean-Louis Chapelier]

Hello,
I have a Lumia 650 phone a few months and I had loss wifi and bluetooth problems.
So, I did the backup and reset the phone.
He spent a long time to retrieve the installed software.
I've also reconfigured my access to e-mail and calendar
- 1 business email Office 365
- 1 personal e-mail FREE
- 1 Professional Office 365 calendar
- 1 calendar on my account Microsoft
Everything worked well until I realized that once Outlook launched of my business account, the screen remains for 5 seconds and return to the Windows page...
Ditto for the calendar. Ditto my personal Free Messaging.
What do I do?
Do you have any idea?
A Council?
Thank you for your help

Finally, I totally removed Outlook from the phone and reinstall it, reconfigure my account and it is OK ... perhaps a problem during the reinstallation of the software !
