    NOTICE: Microsoft is experiencing Office 365 email delivery problems. They are investigating and promise to have an update by 5:30 PM Arizona Time. You may need to resend any emails that bounce back after Microsoft fixes the problem. We will keep you posted.

  • Ryu_Raccoon Ryu Raccoon (@Ryu_Raccoon) reported

    I HATE Office 365. Every single time I change my password their SMTP server fails authentication to send email and their web portal is also dead for me. I've had no way to send email for work for 24 hours so far. It's funny, IMAP works.

  • PGordebeke pascal gordebeke (@PGordebeke) reported

    Bad support from @Office365 @Microsoft they cannot help me on the phone with a problem on a admin account. they say they can't verifier the onmicrosoft domain but that is 100% correct domain.

  • StfBauer Stefan Bauer (@StfBauer) reported

    Who have expected that. IE11, Firefox, Chromium Edge and Safari. Render SharePoint on Office 365 faster the the current Chrome. Sadly it causes a small UX issue in the latest Chrome.

  • OllyData Olly Fayers (@OllyData) reported

    Just in case there are any other UoS folk having difficulty getting into Office365 things - or getting prompted for a password a lot - there must be some kind of issue as a few of us are getting errors. We've passed it onto IT.

  • xharal Zaheer Haral (@xharal) reported

    The new Outlook is so slow on a Mac. Anybody else experiencing the same? @Office365

  • complaint_my MyComplaintBox (@complaint_my) reported

    Really @Office365? popups to switch to Edge in the CSP? Put down the blunt and accept the face that your CSP users are professionals and stop suggesting your half-baked products.

  • smoon_lee Simon Lee (@smoon_lee) reported

    Ok #TechTweeps, I've had a report that the #EAC Portal is broken, Can anyone else confirm this? @Office365 #364Service

  • daanno Danijel Dercksen (@daanno) reported

    @flexibits cardhop doesn't seem to sync with Office 365. Any ideas? Authentication doesn't seem the problem?

  • lizoli Liz Harmer Griebel (@lizoli) reported

    @CAV_LenRichards any chance of an update on the office 365 issues in the UHB?

  • Worrelpa Phil Worrell #Re365 Regarding365.com (@Worrelpa) reported from Nyon, Canton de Vaud

    @LoryanStrant @12Knocksinna @Office365 I got lock back o that. Some teams say they like wiki and works for them. Explain the down side but still when they come back with I cannot find it? Can you migrate it or why can we not do x, y and z. I remind them of the original conversation

  • MarcNYC36 Marc H (@MarcNYC36) reported

    @user47 On my MacBook, I find sheets quicker than excel and It doesn’t slow down like office 365 does when I’m entering in a simple implement data

  • OneSmooveAlpha Mr. President (@OneSmooveAlpha) reported

    @Office365 @Microsoft @MicrosoftSup I am having trouble getting adequate answers about my subscription service and use of MS Forms. None of the non-Microsoft ambassadors are helpful. I need to speak to someone from MS.

  • jpdanner Jason Danner (@jpdanner) reported

    The M365 user accounts aren't new, and any M365 accounts that were used to log into the computer previously still work fine. Just logging in with an account that wasn't previously used on a computer is broken. Just sits at "Just a moment" @Office365 @Microsoft365 @Microsoft

  • shochdoerfer Stephan Hochd�rfer (@shochdoerfer) reported

    @MarkShust the problem for me was that we moved to Office 365. Teams and the web versions of Office are nice to play with but not really stable for daily use. Now I have all the native Win 10 tools + Ubuntu 20.04 for development. WinWin :)

  • WCATech WCA Technologies (@WCATech) reported

    Office 365 users are experiencing delays of ten minutes or more when receiving external email messages. Microsoft is reviewing a recent deployment that may be the source of the issue. WCA is aware of the problem and monitoring. #Microsoft #Office365

  • eric1collins Eric Collins (@eric1collins) reported

    @MarnieWedlake Oh I love Apple! I’ve used/owned Apple tech exclusively since 2006. My issues is that Office 365 doesn’t work for Apple Mail anymore, so I had to download the Outlook app and the layout is much busier.

  • PatrickJMB Patrick Brannigan 💙💙 🕯️🕯️🕯️ Ventilation (@PatrickJMB) reported

    On the Office 365 Managers list, an issue has emerged which prompts the MS HE contact to suggest a workshop. What happens? A message comes in to the list from every institution rep who wants to attend. Not a good use of an information & discussion forum.

  • SSFCFOTY13 Cone of Shame (@SSFCFOTY13) reported

    @Llarian We got an email that there is an Office 365 issue. Related?

  • the_wandr12 The wanderer (@the_wandr12) reported

    looks like office 365 is down

  • larsdobos Lars Dobos dobos.eth (@larsdobos) reported

    @aantonop @GPGTools Sure, anyone can still send fakes, from fake addresses, but at least I can verify that an email from you really is from you. Also, most email providers, e.g. Gmail and Office 365, let you use DMARC to verify the sending server. Not saying it's perfect, but better than nothing.

  • BarryTuckwood Barry Tuckwood (@BarryTuckwood) reported

    Does anyone else's system suffer from slow updates for Windows and MS Office? Yet another interminable update today, not completed outside working hours. @MicrosoftHelps @Office365

  • Fraynchize Frayncheesy (@Fraynchize) reported

  • KrispyRen KrispyRen (@KrispyRen) reported

    @Microsoft Office has easily become the worst application ever. It constantly crashes and when it does work, its slow! Its killing productivity #msoffice #microsoft #Office365

  • JackCooper91 Jack Cooper (@JackCooper91) reported

    @Microsoft365 have you made any update to Office 365 mail application. We've noticed HTML code that wasn't broken before is now starting to break? It's starting to affect more and more users?!!!

  • Guyver1_ Guyver1 (@Guyver1_) reported

    @adbertram love your article on connecting to Office365 via powershell, have you got an article on office 365 automation from an on premise server? Specifically getting around MFA two factor authentication and secure credentials
