Q: Time Machine not working after upgrade to Sierra
The Time Machine (TM) fail to start to backup and it is always "preparing backup....." for more than an hour. This happen right after upgrade to MacOS Sierra.
Another weird thing happen to the toolbar of the Mac Mail. The Junk button is replaced by another button. trying to put it back, but that button become a Delete button.
Please help with the backup problem mentioned above. Thank you very much in advance.

How long have you waited? After a new install it takes a fair while even with an SSD to prepare the first backup due to the number of changed files.
Make sure the TM drive is in the list of items excluded from Spotlight indexing. Log out of iCloud and other cloud services.
