I'm using Outlook 2016 32-bit downloaded from O365 on Win 10. Several times a day, Outlook simply stops in the middle of send/receive and the only way I can get it to recover is to close it and reopen it. This has been going on for months now through multiple version updates. Sometimes it also looses my credentials and prompts constantly for them. Again, I shut down and reopen and Outlook seems to again recognize me as a life form.
Any ideas on what the problem might be?
