    I’ve still not got access and haven’t since just after 9am this morning. Everything was working fine until then.

    I can use my other emails but they are not ones I use for everyday things and m needing an urgent email that was emailed to me today. My husband had no issues with his until around 1pm and no emails since.

    Same error as above when I try on computer, on phone just does nothing. Deleted the account and tried to re add and won’t do anything. This is an absolute joke when you say it would be fixed this morning yet my issues have started this morning. Both are Hotmail email addresses too!

    Hi,

    I'm still having the same issue, unable to log into my account. Do you know when this issue will be fixed as I need access to my emails?

    They say 10u30 AM UTC update; which correspons with 12u30 PM my local time (Belgium).

    So I'm hoping it will be resolved after that ... as I've been having this issue since this morning as well.
