My PC is several years old Dell Inspiron 17R running Windows 10 home which was upgraded from Windows 8.1. 8M RAM, plenty of hard drive. Upgraded to Office 2016 after Windows 10 upgrade because Outlook 2007 was running slow and often froze. Changed ISPs recently also and still slow, 45 - 75 seconds to load with Processing... in bottom left of Office Box taking most of time before it opens. Single IMAP Account, 2 data files, small archive and ost (358KB), all addins closed, ost repaired (had multiple errors) and compacted. In Safe Mode however, about 10 seconds till Profile screen and then only 5 more till Outlook opens. This is wife's account and she checks her mail on her IPAD occasionally. Diane, you helped me move Outlook 2013 to new PC couple of months ago awhile back. Hope you can give me insight on this problem.

PS Microsoft Support assisted because I bought Office 2016 from Trusted Tech Team online who is a Microsoft Partner. Neither could help, Microsoft 1st level told me it was a known problem of Outlook 2016 (pooh). Trusted Tech suggested repair install (didn't help), uninstall/reinstall or clean Windows reinstall as last resort.
