I have a 365 account and use Outlook to calendar events. On my Note 8, I use the stock calendar. I have been using the calendar for over 5 years now. Just the other day, all of a sudden, my all day events shifted to appear on the phone calendar one day early. The rest of the events sync correctly. I know it's not a 365 issue because the Outlook webversion and the Outlook app on the phone show the events correctly. No one from Microsoft can help.
Update: Last week I was on the phone with Micrsoft 365 help for over two hours. No help. The next day I was on the phone with Microsoft general help for 40 minutes. No help at all. Today I have been on (and am still on) the phone with Samsung for 1 hours 12 minutes. They can't figure it out. I keep telling her that it seems to be a glitch since other people are having the same problem. No help.
Don't waste your time calling Samsung. There is nothing they could do.
Update: uninstalled the update but it won't stay uninstalled. I have removed the update, but it keeps reinstalling. I have a Note 8. Does anyone know how to keep it from reinstalling?
I am having the same exact problem...from my outlook to phone, goes back 1 day...if I do an all day from phone to outlook...doesn't show up...hourly are just fine...
I have Tmobile. I believe yesterday. My boss has a Galaxy s8 also and called me that his phone freaked out...so when I looked, mine had too. he doesn't have tmobile.
it may have been last week...I think my boss has AT&T. Def seems like a samsung issue...I just had to go move ALL my all-day appointments in my phone to the correct day.
Galaxy S9; Verizon; My issue started August 12, but it had been a while since I scheduled an all day event (time off). I thought I made a mistake with scheduling. Then I see it again for this coming weekend, and went to fix the "mistake" and see that my outlook is correct whereas my phone is incorrect. No amount of trouble shooting fixes this.
Issue: When "all day" is checked on an MS Outlook calendar event, it appears ONE day early on the Samsung mobile calendar.
