Using posts and articles found here, I've successfully Synced two computers using Outlook 2007 and Outlook.com and Gmail. Gmail is the mail account and Outlook.com provides the sync for Calendar. The calendar sync works well with changes moving quickly and calendar categories being synced as well. I have also wanted to sync with Outlook for Android on a Galaxy S7. With the goal of email coming from Gmail and calendar from Outlook.com. I have successfully added both the accounts and have Gmail mail working well. I can also see my outlook.com calendar on Outlook for Android with one problem. Color coded categories do not seem to sync to Outlook for Android. There is another problem as well. While I can add and edit events on the S7, I cannot edit or delete events that were created on either computer. Without that ability, the mobile device "sync" is not useful. I've noticed that Outlook for Android lists my gmail account as an event attendee. I'm wondering if it is treating the Outlook for Android user as a different user than the Outlook 2007 (PC's) users and thus restricts change rights to the PC created events on the S7. I've been unable to test that theory because I've been unable to find any settings which seem to define the calendar user for Outlook.com (the calendar is set to the outlook.com account). I'd appreciate suggestions, advice, etc. Thanks!
