Windows 10: Unusual Message from Outlook 365

Is there a way to not have it displayed when the condition has occurred?

Problems syncing Outlook.com email with Outlook 365 and with Windows Phone

I use my Outlook.com email in three ways:

• via the Web in IE10
• via Outlook 365 on Windows 7 laptop
• via Windows Phone 8 on Lumia 920.

I am experiencing problems syncing with Outlook 365 on Win7 AND with Windows Phone 8 on Lumia 920.



The longer I leave a message in my Inbox, the more copies of that messge will appear duplicated in Outlook 365 on my Win7 laptop. Someone suggested deleting my Outlook.com account from Outlook 365 and then re-adding the account, which actually solved this
problem for a couple of months. Now the problem has returned: multiple duplicates of the same message in my Outlook 365 Inbox. Am I forced to go through this arduous process eveytime this problem happens?



Also, there are some messages that, when deleted using any of three ways listed at the top of this message, will remain in my Windows Phone 8 Inbox. I will repeatedly delete them and these few messages always return to my Windows Phone 8 Inbox.



Please note that when using Outlook 365 or Windows Phone 8, I have no problems syncing with my other two email accounts, which are not Microsoft accounts.



Will someone PLEASE help me fix my two sync problems of my Microsoft account with the Microsoft software and Microsoft hardware?



Thank you very much for your time and help.

Outlook 365 Fails to send message 0x800ccc0F

Good evening, Al. I can tell ya that Outlook is the problem child of Office 365 2016. It's given me nothing but grief since I've had it, but the rest of Office is just fine.

For a couple months, every time I opened Outlook, I was forced to give my password. Since the last cumulative update for 17763, the password demand has stopped; however, I have one email address that Outlook seems to have lost its ability to collect mail for. I get the following message when I try to get mail for that address.





Edit: This is a dual boot machine, and on my Insider partition with Build 18312, Outlook seems to behave quite nicely and I can collect email for all my email addresses.
