    Anyone else curious if Microsoft spent the same amount of security investment protecting the hacked versions of on-premise Exchange Server as Office 365? #CyberSec

    @mvyrmnd Amen to that. Just migrated my last client still with an on prem Kerio server into office 365 last week

  • journeymanped Journeyman Pedant (@journeymanped) reported

    @JamesBSumner you don't need them to know about it, just run it locally, and it works against the Office365 server. I can confirm this with many 1000;s of emails and calendar events over the last 6 or so years

    @nekr0z My early Dreamhost experience was much the same. I loved Dreamhost! I moved my mail to Office365 years ago. I finally dropped Dreamhost after dial-up server speeds. Now I use AWS Lightsail. I would rather not use AWS, but this is the closest thing there is to the old Dreamhost.

    @MicrosoftHelps Hi! My office 365 gives me an error everytime I try to load mail. When i go to admin also, it gives me an error. Please help. I am being charged for my subscription but can't access my email!!

  • hoyty Hoyty (@hoyty) reported from Sammamish, Washington

    @hacks4pancakes I totally agree and understand this as I have dealt with crappy devices like copiers bought 2 years ago that won’t talk to Office 365. However if you are truly only using it for SMTP relay then disable HTTPS inbound from Internet. If it isn’t a live mailbox server you don’t need.

    Hi folks. Need your support team’s help in sorting out my login from GSuite (now Workspace) to Office365 plz. Could this be looked into urgently? Thanks a million. @Calendly

  • tweet_alqamar al Qamar (Karl Wester-Ebbinghaus) Ⓥ (@tweet_alqamar) reported

    @BenDumke Uninstall the KMS Server delete the _vlmcs entr(y)ies in DNS. Use VAMT to double check compliance if all Win 10 machines are really using ADBA. Office 365 is freed from that.

  • goldstein_aa Adam Goldstein (@goldstein_aa) reported

    @alycosta I got the same error when I tried to embed Office 365 (Excel and PowerPoint) a long time ago. Really wish there was some way to do this.

    Need some Office 365 advice. So, we use it for work and every time we sign in, it sends us a code on our mobile to put in. I’ve got a new number and I now can’t sign in to change my details because it’s sending the code to the old number... any advice?

    @SQLAllFather @MicrosoftTeams Yes, and if you have different Office365 logins (as I do) it writes a scrap to CredMon so next time you try to log in to Teams as someone else, you're in the loop of Teams login hell because you weren't properly closed out. 1/

    @Office365 why after days and days of waiting for the Data Protection Team to assist with a locked out O365 tenant, do I NOT get a phone call and then an email showing that the problem was resolved/case closed when it has not been? This is the 2nd time!!

    @Office365, @Office, why do I need to sign into my account every 15 minutes? It continues to tell me you’re having an issue with my account? #TechSupport #Office365

  • ttwarneke Trip War (@ttwarneke) reported

    @J_Dot_J I think you failed the shibboleth because you called it "the Windows suite" instead of Office365. Guys, this one's chip isn't working right. Someone needs to take note and make sure its correct on the 2nd shot. :P Haha, though I'm jealous cause MA is still slow rolling out.

  • MiddleTommy Tom Tucker (@MiddleTommy) reported

    @shoogn17 @BlazorBot Spent a year of off and on trial and error with auth in blazor using existing office 365 accounts. Finally I buckled down for about 20+ hours over a few days blocking out everything else to get it working. Then I started developing. There is a lack of real world auth examples.

    @Apple @Office365_Tech How do I fix my Outlook? IMac operating big sur, uninstalled and reinstalled Office 365. Outlook crashes, needs repairing, 196GB free space, says it can't repair because it needs 110GB. Created new profiles, nothing works. Do I give up?
