Bug 483004

SUMMARY

When I wake the computer from sleep, kmail EWS (O365) does not wake up and remains offline. Clicking `Update Folder/Update Folder and all its Subcontents` will start showing Kmail doing stuff. But then the program will crash. In order for EWS service to go back online, I either need to login again manually or restart app

NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.

4. Wake computer from sleep
5. open kmail from tray
6. right click `Update Folder/Update Folder and all its Subcontents`
7. EWS mailbox stays offline
8. Click settings --> configure kmail --> recieving --> modify --> EWS settings `reconnect` 
9. Sometimes a crash will happen

However, once program goes `offline` it is impossible to get it to go online without reauthenticating or restarting kmail
