It is a known issue of Office 2013. As stated here, follow these steps to solve the problem:
- Open Registry Editor (
Start > Run > regedit) - Go to this container:
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Identity\Identities\youralias@domain.com_AD
User settings in Registry Editor - Delete this registry key:
"SignedOut"=dword:00000001
If you don’t see that registry key like it was in my case, simply add it.
