I have this problem - Outlook 2016 doesn't accept password or app password - and i think it is a growing World wide Microsoft problem :-(

See also here: https://www.reddit.com/r/Outlook/comments/19dx64p/outlook_2013_windows_10_suddenly_not_accepting/Outlook gives me this: (startede yesterday)

I have 2 PC's with HOTMAIL accounts in Outlook 2016 ...

They both have this error.

I do get mails ... but I can´t send mails. Yesterday it did work for 1-2 hours ... but right now the error is there all the time :-(

Please help me.

Thanks in advance

Pierre

    Hello everybody,

    I am wondering if some of you are Microsoft 365 customers and are having issues with Outlook.

    We are a company with approx. 6500 users and some of them have issues.

    When we force a reconnect of the internet connection, then the issue is sometimes solved immediately, sometimes the reconnection has to be repeated several times.

    That matches with some earlier posts, stating, that only some portion of the Exchange Online Cloud Endpoints are affected.

    So we suspect that this issue here is also our issue but we are not sure.

    Core i14 is out now. My core 2 (not i2) is basically generation 0. No problems with it, outlook has been fine.

    I've been having the same issue..
    Fixed for a few days and then came back as noted by others..

    I'm using emClient and connecting using Exchange (EWS) and app passwords.

    Just wanted to add that if I keep pressing ok on the password prompt after multiple attempts I eventually get connected and then works ok for hours.. Unless i flush dns, or restart my network adapter which then asks for password again.

    Funny thing is that on emClient forums they insisted and still do, that this is happening because Microsoft had announced that they plan to disable all basic authentication back in 2022 and now this change is taking effect for all servers.
    Microsoft and basic authentication - personal outlook accounts - Announcement - eM Client
    Is this in any way valid? No matter how many times I tried expressing my doubt on this they kept replying the same thing..
    I even sent them this post by Microsoft which points to this thread while it was on INVESTIGATING status..
    Eventually they suspended my account and locked that thread.. :D

    In any case my guess is that if this was the case it would not work no matter how many times I tried logging in..
    And also as I already said it worked just fine for two days as noted by others in this thread..

    It was not about the number of core but the processor generation (we are at core 13th generation)
