    @Windows , @Microsoft , @Office365 I am office 365 and Windows user. I am facing a big trouble. I have 3 calandras and I can’t select default calendar. So, every time I enter anything in calendar I have to select the calendar which makes an extra step for me. Can you help me?

  • YFelice3 Y Felice (@YFelice3) reported

    @Office I can’t login to or receive email from Office 365 today/ Outlook. Please advise

  • bibelhausen Kevin 🐝🐂 (@bibelhausen) reported

    @MikeBotkin_ You should be able to do this within office365. Upload document to OneDrive, give other party access, redline/ track changes within central location. Now if you’re telling me I could white label that as a service… I’m down 😬

  • whotookmyname Paul (@whotookmyname) reported

    Some days I hate Office 365 (business plans) and some it's Google WorkSpace. today is the latter. If what I think is the problem then it's a stupid setting they have in my eyes.

  • JuanG_Van Juan Gonzalez T (@JuanG_Van) reported

    Does anyone have issues with Word styles in SharePoint? We have issues where styling changes for no reason. #MsWord @OfficeSupport @Office365

  • Ocramius 🇺🇦 (@Ocramius) reported

    Need: office365 -> SMTP/Exchange -> Gmail importer. Anyone got a docker-ish solution for that? I'll slap it on a server somewhere, but I really don't want to have anything to do with this ******* Outlook stuff.

  • thecrankysa CrankySysAd (@thecrankysa) reported

    My hot take is Microsoft should have a homelab license that includes Office 365, Azure credits, and licenses of Windows Server,System Center, SQL, and SharePoint (On Prem). I'm aware there are trials, but ✨some✨ people have a rack full of servers they want to run 24x7.

  • JoachimAstel Joachim Astel (@JoachimAstel) reported

    @mrimann @MSFT365Status DNS Outage for mail servers at #office365

  • simplydotcom Simply.com (@simplydotcom) reported

    We are currently seeing a global issue with sending mail to Office 365 domains. (DNS lookup fails).

  • Tristan_Collins Tristan Collins (@Tristan_Collins) reported

    Anyone else using #neomutt and #office365 finding it not working today? "No authenticators available or wrong credentials"

  • beyjohn1 John (@beyjohn1) reported

    @MicrosoftHelps I can't open the Office 365 Admin Center at some locations. I've tried clearing DNS, resetting the browser, and tried another browser, but nothing seems to work. While at another office, it loads with no issues. Can't get to some status pages either.

  • Work_ant Work to live (@Work_ant) reported

    @MeMeowvi @gautambhatia88 @saikatd That works in some cases. How about issues like below - 1. Lets say Office365 has an outage and loses data. 2. What if a food item by a national firm is contaminated and multiple folks are impacted 3. Say a Govt service has a glitch - say fastag has a privacy breach

  • oneredmouse One Red Mouse (@oneredmouse) reported

    We are seeing issues with both client and our hosted mail servers sending mail to users on Office 365 domains. (DNS lookup fails if you are interested) Downdetector is showing reports of problems

  • LaurentCREPET Laurent CREPET (@LaurentCREPET) reported

    Hi @Office365. It seems there are issues resolving DNS records like *.mail.protection.outlook.com.

  • HenriGauthier19 Henri Gauthier (@HenriGauthier19) reported

    @AngeZanetti @lifesaverluke Mainly to do admin taks. Typical stuff: - Manage Office 365 Admin / emails - Web Hosting - Various advice on security and SaaS products - Being "here" for any technical issues.

  • NarnaLeighDD Narna (@NarnaLeighDD) reported

    @i_dreamof @Microsoft Hi, after talking with the Microsoft help team, the problem with my account was that my storage was full. I was able to access my emails on a PC which allowed me to delete some items but in the end I just bought Office 365 to get more storage.

  • mrimann Mario Rimann (@mrimann) reported

    Oh, it's DNS again? Can't reach the mailservers of several #office365 tenants because the hostname is not resolvable at the moment. @MSFT365Status confirms an issue (EX397744). Hope they can fix that soon... #dns #monitoring

  • tgraupmann Tim Graupmann (@tgraupmann) reported

    @MSFT365Status @MicrosoftHelps It seems that because of how our security policy is setup, when the user session expires, we run into this issue. So it's not an outage, it's just dynamics not handling expired sessions properly. Our office 365 sessions all expire at the same time seeming like an outage.

  • GarethRossUK Gareth (@GarethRossUK) reported

    @MicrosoftHelps @onedrive something went wrong message for about two days on both desktop and laptop. However it's working fine on Android all with same account. On office 365 annual subscription only used half of available storage. Website is able to load to my storage no issue.

    @LuiseFreese Can you explain this login feature in mock? What is the point of it if this is Power Apps with OOB office 365 auth

  • quofles Anusha (@quofles) reported

    @RishiAlwani @Office365 im offering 2 companies the opportunity to use my data , i dont get the problem here :(

  • xzopia Simon Killen (@xzopia) reported

  • LPLobinske Louise Pare-Lobinske (@LPLobinske) reported

    Dear #Microsoft, It would be nice, now that we're on #Office 365 or whatever, if we had #Excel formulas that actually updated every time we added or subtracted rows or columns. Sincerely, Everyone who's ever beaten their head against the wall trying to find a "$4,000 error"

  • jonofnmi Jon (@jonofnmi) reported

    microsoft word to google doc because you're no longer a student and they've closed down your office 365 account pipeline

  • wincent Greg Hurrell (@wincent) reported

    A while back I moved some spreadsheets off of Google Sheets (to reduce the number of eggs I have in Google baskets) to Office 365 (seeing as I get an employee discount). But I am having real trouble getting past the UX/UI flaws. So many cut-your-own-fingers-off sharp edges.

    I cannot be the only one who finds it hard to maintain thought all my errors are asking for attention. @Office365 Could you please add hotkeys for on/off spell check?

  • onepict Esther Payne (@onepict) reported

    @extremelabs @nacnud About 5 years ago I saw some wierd routing when I was trying to traceroute to see why a client was having issues sending to an office 365 recipient, it reached a DC in Kentucky and kept Pinging around between 2 servers and timed out. It doesn't take much to screw your network.
