Fix for: Can't activate Outlook 2015 on Mac "Another account from your organization is already signed in on this computer."

Copied from this thread

1. Quit Application.
2. Open Library folder of current user. (to use OPTION key)
3. Delete following files from Library\Containers
com.microsoft.Office365ServiceV2
com.microsoft.onenote.mac
com.microsoft.outlook
Note: com.microsoft.Office365ServiceV2 is sharing with Outlook/OneNote because new apps uses same activation app that is Office365ServiceV2.app
4. Delete following files from Library\Group Containers
*.ms
*.Office
*.OfficeOsWebHost
Note: OfficeOsWebHost created by activating Outlook only, maybe.
5. Boot KeyChain.app and remove following application password if need it.
<For Org ID>
Unknown
Microsoft Office Identities Settings 2
Microsoft Office Identities Cache 2
<GUID> (Type is MicrosoftOffice15_2_Data:ADAL:xxxxxxxxxxxxxxxxxx)
<For Live ID>
Microsoft Office Identities Settings 2
Microsoft Office Identities Cache 2
<GUID> (Type is MicrosoftOffice15_2_Data:Live:cid=xxxxxxxxxxxxxxxxxx)
Note: these time stamp is same or nearly. Be careful, these keyChain object for activated account is shared with Outlook and OneNote as you know.
