  • JohnnaCantWait Johnna ✨🧀 (@JohnnaCantWait) reported

    @caitycoyne Your account admin should be able to open admin portal > Exchange > Mail Flow > find the rule that creates a caution when criteria are met & disable it. One issue is this might disable it for your whole org (anyone on the same office 365), including ppl vulnerable to spoofing.

  • eevasilin Eeva #oikeusolla Silin (@eevasilin) reported

    ..for referring to the current item is basically trial and error. Bugger Microsoft Office 365 with a pointy stick.

  • Johnnyboythrash Johnny Farrow (@Johnnyboythrash) reported

    So should the calendar on Outlook on @Office365 not show work hours anymore? Is this an error or am I now destined for people to try and book meetings with me whenever they want. Is this just wfh now?

  • brandon_dubski Brandon🆗️ (@brandon_dubski) reported

    Office 365 having issues so if you're emailing your wifes boyfriend about vacation spots he can take her to you might have a bad time.

  • spinicist Tobias Wood (@spinicist) reported

    @dsquintana Working with LaTeX locally mostly defeats the point of Overleaf - but I do find the *** integration handy for uploading figures. The day Office 365 goes down I think there will be larger problems than working on my next paper!

  • 12Knocksinna Tony Redmond (@12Knocksinna) reported

    @jsnover Very nice. I wrote that book with your wife's help... I seem to have spent the last 30 years documenting ALL-IN-1, TeamLinks, Exchange Server, Office 365, and now Microsoft 365. When will it all end?

  • mel_thegreat Melissa Blue, feeling like Dakota Gray (@mel_thegreat) reported

    @Dragon_Age_Fans I started to have issues with it and that's the only reason I switched to Office 365. I just wanted consistency.

  • NP_TechUpdates SUNY Paltz ITS (@NP_TechUpdates) reported

    We're seeing email delivery issues to Office 365. It appears to be impacting at least mail from Hawkmail and other Google mail, but some other sources are impacted as well. We've reported the issue to Microsoft and are waiting to hear back. More updates will be provided soon.

  • GoDaddyHelp GoDaddy Help (@GoDaddyHelp) reported

    @jethani_sandeep Hi there, we can assist with any Office 365 technical issues. Our support is limited when it comes to integrating it with a custom email application, mainly because that's not our product. We can, however, try to steer you in the right direction. What application are you trying

  • rickzeleznik Rick Zeleznik (@rickzeleznik) reported

    @SPCPartyPatrol @Microsoft @Office365 No doubt on the client. But Project Online too you think? There's a flourishing 3rd party mpp server SaaS market, and the functionality of PWA seems like it hadn't been updated in forever. Update rumors?

  • svrc Stu Charlton (@svrc) reported

    @CharlesTBetz I assume they want the Scrum team to run their own email server and don’t use Office 365 :-)

  • outbackdingo dingo (@outbackdingo) reported

  • EmmaKEdDev Emma Kennedy (@EmmaKEdDev) reported

    Anyone else's Office 365 apps just get stuck in a sign in loop where eg PowerPoint decides you're logged out but when you sign in, just keeps asking? No error message, just a constant loop. I've tried restarting three times & now given up.

  • Farzlepot Another Matt (@Farzlepot) reported

    @CSurvivor9 Office 365 is beyond broken at the moment. I wouldn't worry too much about it. I mean, other than the sensible amount of worry a paying customer should have for a broken product, anyway.

  • SPCPartyPatrol SPCPartyPatrol (@SPCPartyPatrol) reported

    @rickzeleznik @Microsoft @Office365 yeah having 2 clients - web and desktop - to edit one file in the server might need some help. I've seen where people are checking out the file in sharepoint, making edits to XML (?), then saving it/uploading it back, and checking it in. Seems risky/unsupported, but a workaround.

  • KrzmarzickMJ Dr. Mark Krzmarzick (@KrzmarzickMJ) reported

    I've lost 2 hours more or less today because my institutional Office 365 license and computer weren't talking. Who knew the third reboot would magically solve the issue!? What was so bad about using hard product keys and licenses again? Every 2-3 months I lose time like this.

  • GeoffreyLentner Geoffrey 🧢 (@GeoffreyLentner) reported

    I'm going through my biannual mailbox cleaning spree (~40k emails) for my #Purdue @Office365 account. I use @OfflineIMAP to manage locally with better tools. The server just gave me a 'NO - Request is throttled...' response. Meh.

  • strixus strixus (@strixus) reported

    ... Has anyone else had a weird issue with office 365 showing meetings 30 min earlier than they actually are?

  • Dartz_IRL Dartz (@Dartz_IRL) reported

    Uninstalling the Office 365 trial from my laptop inadvertantly nuked the libraries Firefox needed to run. It was a 20 minute fix, but a frustrating one.

  • MrPapercut ߛߛMischa (@MrPapercut) reported

    @renebakx I think the Windows 10 Accounts browser plugin does that, right? I experience no issues with Office365 and Brave. But MSEdge is fine, it's my "second" browser for testing and stuff. Also Edge has the better built-in game at edge://surf/

  • ViktorKalmar1 Viktor Kalmar (@ViktorKalmar1) reported

    Learn about the how the simulations for defender for office 365 wear levelling your SSD health just download the hard disk sentinel application and check your SSD or HDD health check the problems occurred between the communication of the disk and the host

  • TheSmileCEO Jim Moss (@🏡) (@TheSmileCEO) reported

    My favourite part of this Rogers outage is that my office365 account requires an authenticator app that requires cell data. How about no? Maybe I could fax it to them? Morse Code? Maybe send a raven?

  • DavidPrecht David “The Real Raye Penber” Precht (@DavidPrecht) reported

    I guess Office365 is down...is a sentence I felt ***** for writing.

  • dimitribouniol Dimitri Bouniol (@dimitribouniol) reported

    @neilsardesai Mostly an issue with Office365 accounts, since the email domain doesn’t match the SSO domain, so no suggestions are shown 😔

  • VictoriaTheTech Victoria Thompson, M.S. 🥐🏳️‍🌈 (@VictoriaTheTech) reported

    @iamDrWill I'm a big Surface fan but I mostly use Office 365, so the new computer was more of just an upgrade for me. Windows Hello is a huge plus for me, though. I like being able to sign in by facial recognition.

  • thomasfritz_ fritz (@thomasfritz_) reported

    Hey @Office365 there’s no reason for me to need a security code texted to me every time I try to sign in. Just relax buddy. @BillGates fix this/Venmo me please

  • Htom__Sirveaux If you don't think black lives matter, suck my *** (@Htom__Sirveaux) reported

    @findkylesxbox @UlrichPro1 @Wario64 I administer both a Discord server and multiple Office 365 tenants with 300+ users. Teams is *not designed* to be used outside of a professional environment.

  • clandis607 Clandis Smith (@clandis607) reported

    @MSFT365Status Getting deferred and temporary server errors when trying to deliver external messages to office 365. I also do not see the advisory in my admin center.

  • alsydlad asydlad (@alsydlad) reported

    Can someone fix the bug in the Outlook app on an iPhone - it’s a nightmare. @Office365 @Outlook @MSFTnews i want this fixed ASAP please folks.

  • dannyb1889 Dan Bumby (DAN & DAN) (@dannyb1889) reported
