  • jammi_dodger94 Jamie Raines 🦖🥔 (@jammi_dodger94) reported

    Been trying to fix our very messed up @Outlook calendars for DAYS now, and was seriously advised today on a help chat that permanently deleting the calendar would resolve the issue. Like yes, but then I wouldn't have a calendar 🙃

  • adamtiley Adam Tiley (@adamtiley) reported

    @zacbowden Thank god someone said it. Been a massive influx of these all of a sudden in the last month or so. @Microsoft @Outlook fix it please!

  • MrsCClay22 MrsC🦄 (@MrsCClay22) reported

    @JimDavisMTG @Outlook I'm having the same issue, also been the last week or so. I sadly don't have a solution other than deleting each one... good to know it isn't just me!

  • s_p_enright <spe /> (@s_p_enright) reported

    Anyone getting #email errors like "451 4.7.500 Server busy. Please try again later from" and "452 4.5.3 Too many recipients (AS780090)" from @Outlook? I don't use Outlook servers. I use my own servers. Happens randomly, not all email. Is there a trouble-ticket system for Outlook?

  • siraguso Frank C. Siraguso (@siraguso) reported

    @Outlook Dear outlook: Not my problem: Unfortunately, messages from [191.96.165.85] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3140). You can also refer your provider to ...

    @screamingofcak1 @Outlook If they were from real people or places, it would be no problem. Just in this case it’s so easy to tell there fake because real Netflix and 99% of other companies don’t use emojis in there address or subject line. So, it’s blatantly obvious, to me at least, that they’re fake.

    Why does the outlook mobile app send your authentication details in plain text to Microsoft first then authenticate with the remote mail server? #Outlook @Outlook #OutlookSecurity #Android

  • TigerIre Ire Tiger (@TigerIre) reported

    @Outlook why don't you fix your mobile app

  • TBat416 Bugs (@TBat416) reported

    @Outlook My outlook is not receiving emails and senders are getting the error message "remote sever is misconfigured". Your chat support is useless as well. Can someone offer advice on this? I'm missing important emails.

  • kre8ivelady August P (@kre8ivelady) reported

    @Njopling1 @mcnees @Outlook I've had this same issue with hotmail as well.

  • msbellows M.S. Bellows, Jr. (@msbellows) reported

    @HieronymusMcG You'd think @Outlook would have fixed this, if only because it must be a problem for their employees too.

  • Pantherman82 Doomwaffl3 & Friends (@Pantherman82) reported

    @JimDavisMTG @Outlook Following, I have the same issue. It's getting ridiculous

  • agturcz Agnieszka R. Turczyńska (@agturcz) reported

    I remember the struggle and disappointment of the Open Source community when @Microsoft has introduced TNEF to their @Outlook suite years ago. And they are still using it causing problems when you want to forward an email to someone who refuses to be vendor locked-in.

  • robbowwfc Rob 🐺 (@robbowwfc) reported

    @Outlook PLEASE PLEASE PLEASE fix your junk filters!! This is getting infuriating having to clear 5-6+ emails a day

  • grumpybozo 🆘Bill Cole 🇺🇦 (@grumpybozo) reported

    One of the best bits of competitive sabotage in the email biz is the @Outlook/Hotmail S3150 error. Mail gets rejected, but @MicrosoftHelps bots just shrug and say there's no blockage. But there is. Telling customers truth: Hotmail/Outlook is unfit for mail AT ALL. #Sysadminnery

  • ChrissonatorOFL Chris (@ChrissonatorOFL) reported

    Well, I'm glad I created an alias when I did @Outlook since that feature is going away. I had to create a new alias to stop login attempts to my email. 🤷

  • HarryHarding91 Harry Harding (@HarryHarding91) reported

    @Outlook hi, 3 emails in our business are down and can’t receive any emails since yesterday. Outbox working but inbox definitely not. Have checked storage & there’s plenty left (we have 50GB storage limits & not near the threshold at all). Tried logging out and back in, pls help!

  • Therealmattbon1 Therealmattbonk (@Therealmattbon1) reported

    @JimDavisMTG @Outlook Been having the same issues.

  • laurashleyy TiffanyBeatz (@laurashleyy) reported

    I swear @Outlook is the WORST and don't actually help with any issues

  • caitlinecarey Caitlin Carey (@caitlinecarey) reported from Melbourne, State of Victoria

    @ItsSpeltWithAC @Outlook I’ve been having this issue for a week or so now, dozens of spam every day - I DM’d @Outlook and they did nothing! Emails from trusted sources go to junk but clear phishing emails make it through - sick of it!

  • zob879 uıʇsnɾ (@zob879) reported

    @Outlook omg stop with the changes. The past 3 changes to outlook have been terrible.

  • jonestowne jonestowne (@jonestowne) reported

    @screamingofcak1 @Outlook Were they from real people/places, it'd be no problem. But in this case, the emojis are indicative of them being fake; as real Netflix (and 99% of other companies) don’t use emojis in their address or subject line. So it's blatantly obvious that they’re fake. Seems an easy fix.

  • LokoCrazyJr CowbowSavy (@LokoCrazyJr) reported

    I don’t understand why @Microsoft can’t fix their @Outlook from all these scammers man! C’mon! Enough is enough!

  • SeanT3181 Sean Trejo (@SeanT3181) reported

    @Outlook I haven’t been able to use the outlook app on my iPhone 12 mini with iOS16 since version 4.2243.1 was released last week. The app just opens and crashes immediately. The latest update released today has not fixed the issue. I need this app to do my job! Please help.

  • andy_ibberson Yowzerbowzer 🧩 (@andy_ibberson) reported

    @Outlook are the spam filters down? An inordinate amount of tripe appears to be in my focused inbox and shows no signs of going away.

  • ShaunClarke04 shaunclarke.co.uk  🪱🐀 (@ShaunClarke04) reported

    @jammi_dodger94 @Outlook Hahaha yeah. Microsoft products NEVER work for me. Can’t believe I used their ecosystem for what? 2 years?? I can barely open a word document without issues!

  • sandratoms01 Sandra Toms (@sandratoms01) reported

    @Frandrury1078 @Outlook He's really good you should talk to him about the issues he will get it fixed

  • HarryHarding91 Harry Harding (@HarryHarding91) reported

    @Outlook Sadly this hasn’t helped. I can login and have plenty of storage but my inbox on 3 outlook accounts have been down since yesterday. Outbox is working but not the inbox

  • HarryHarding91 Harry Harding (@HarryHarding91) reported

    Anyone know how to fix an @Outlook inbox? It’s not a storage issue and have tried logging out/in but to no avail 😞 outbox working but no inbox since yesterday #pleasehelp

  • rubernck21 Alex (@rubernck21) reported

    @Outlook PLEASE FIX YOUR SPAM FILTERS!!!!! I don't know why I have to MANUALLY mark OBVIOUS spam/phishing emails 10+ times a day!
