"We're having trouble getting new e-mail items" - Microsoft Community

hello everyone. have been struggling couple months outlook 2016 error message automatically return me outlook application. error message states "we're having trouble getting new e-mail items" , specific error message "if signed in account <here exchange e-mail address listed> skype business(lync) or windows or mac outlook clients on other devices, try signing out of them." 

possible solutions have tried have included, ensuring not signed in skype profiles on device. uninstalling , reinstalling office 365 completely. removing skype devices. have tried messing various settings (too many list here). huge problem because in middle of powerpoint presentation , when error message comes in outlook, stop presentation , take me outlook. of course, solutions have found work shutting down outlook or using different e-mail client program.

any ideas on coming solution can continue use outlook? 

thank you.

hi aaron,

thanks private message. firstly, i'd confirm whether login account in other devices such windows, phone or other macs. if yes, please log out , check again.

then, clear skype business cache mac:

1. go finder > press command+shift+g > type in /users/<macusername>/library > delete following files:
    caches > com.microsoft.skypeforbusinesstap
    internet plug-ins > skypeforbusinessplugin-15.8.bundle
    keychains > files beginning oc__keycontainer
    logs > skypeforbusinessplugin
    preferences > com.microsoft.skypeforbusiness.plugin.plist , com.microsoft.skypeforbusinesstap.plist
2. go finder > press command+shift+g > type in /users/<macusername>/documents > navigate microsoft user data > delete following folders: skypeforbusiness-2016-mac-1839-preview.
3.  open keychain access /applications/utilities folder.
4.  delete keychains starting oc__keycontainer.
5.  in login keychain, delete e-mail address certificates.
6.  empty trash.
