“This is because the current M365 license does not have shared activation rights. You need Business Premium or E3 and above for this to work [re: Teams/Outlook constantly asking users to sign in again on a single RDS server (non-clustered)]”
“I am pulling my hair out. I want to run Sharepoint user and guest diagnostics. Instead I am getting support assistant that keeps popping up even telling me run the diagnostics but I cant get to it. Even Microsoft’s shortcuts just brings up support assist. Switching it off and then trying to get to it just brings up articles of the shortcuts I am clicking. Microslop. I just need to see why a user / guest gets shown up as none when checking permissions on Sharepoint site where the user is setup as”
“Hi All, In New Outlook Salesforce periodically throws errors i.e. is unstable. Attached an error screenshot. Initially thought it might be use's PC profile related. However, it may work after restart but then one day stops again. Please advise what it could be. Happy to try Microsoft Office package Online Repair if it is the culprit. Thanks. submitted by /u/The_Spicy_Nonno [link] [comments]”
“This is a weird one, hoping someone else has seen it. I have a 365 user who can't use either the New or Legacy Outlook versions on MacOS for his work email. Legacy Outlook won't let him log into the account, just says "please check your credentials" even though it doesn't prompt for a password or MFA. New Outlook logs in just fine and he can send emails but the folder list just shows Drafts, Inbox, and his Online Archive. No Sent, Junk, Trash, or any of his Inbox subfolders”
“Has anyone found a better way of contacting Microsoft Support for a Microsoft 365 tenant lockout? We have a serious Entra Connect sync issue which has left all of our Global Admin accounts unable to log in, so we can't raise a support ticket through the admin centre. I've tried the UK Microsoft support number, but I just get the AI/automated system and it hangs up without getting me to a person. I need to speak to someone in Microsoft's Tenant Recovery/Data Protection team. Is there”
“Hello! We are preparing to deploy the Salesforce to Outlook integration and trying to see if there's a solution to an issue we are having. If users login from the desktop version of Outlook for the first time it errors out until they launch the addin from the web version, which links them to Salesforce and adds them to the user mapping. Has anyone found a way to mass import the mapping instead of each user doing it individually? submitted by /u/reddeator94176 [link] [commen”
“I'll admit not the best m365 admin since I do not support a big company and just do not do a lot of stuff with it so I thought I would ask. I have been updating documentation in regards to a small non-profit that I support and ensuring that if something were to happen to me then someone would be able to pick up and continue on. One area I missed was making sure that the M365 accounts had a back up authorization capability vs the MS authenticator on my phone. I had a yubikey so I configured t”

“Hoping someone here has run into this before, because I've been going in circles for a while. Setup: Microsoft 365 Business Standard tenant. I'm Global Admin (permanent assignment, not PIM — we don't have Entra ID P2/Governance so PIM isn't even in play). Trying to centrally deploy the "Claude for Microsoft 365" AppSource listing (bundles Word/Excel/PowerPoint) and separately "Claude for Outlook" (beta) via Microsoft 365 Admin Center > Settings > Integra”
Thank you very much This fixed this issue. User was in a Role Assignment policy that didn’t have custom apps and market place apps.
“I've had issues with windows update or M365 update in the past, especially the April (I believe) update which I had to uninstall because it slowed everything down. Last week I rebooted the server on a weekend after running some updates and after a couple of days a single user complained, and by Friday it was everyone having issues with Outlook. I noticed RDS was a bit laggy for me via Screenconnect too. CPU and RAM utilization are at 50%. All updates are applied and all Outlook add-ins remov”
“I cant get into CIPP (just repeated "Please wait while we log you in...") , and just went to the Identity portal in Office365 and could not add a TAP for a user. Looks like it may be a fun morning for Microsoft users. submitted by /u/kribg [link] [comments]”
“I have a user at our corp office who keeps getting disco'd from the outlook fat client. the fix is to signout of excel and then close outlook and log back in to get the mfa code and re-authenticate. no one else is having these issues. win10 1809 with office2021 ltsc on the image. azure sign in logs are normal, but no indication of why she keeps getting booted. ps - also re-added her work account in win10, didn't make a different....it started yesterday and seems to only be stable for abo”
“what regular (weekly, monthly) maintenance tasks you guys perform in your M365/Intune enviro? Check non-complaint devices, forgotten user accounts… that type of things. submitted by /u/covex_d [link] [comments]”
“I'm hoping someone has come across this before. We have a Microsoft 365 tenant where the Salesforce Outlook add-in suddenly disappeared for a single user. It had been working previously. Here's what we've found: Salesforce app is deployed to All Users in the Microsoft 365 Admin Center (Integrated Apps). The add-in works for my admin account. The affected user cannot install Salesforce from either Classic Outlook or Outlook on the Web . To rule out Salesforce, I tried installing Linke”
“About 20 mins ago I got an MFA prompt os MS Authenticator. Saw the notification for my account but didn't click it. Logged in as admin to our MS 365 portal and checked sign in logs...nothing... No successful or failed attempts. Checked a few mins later and my admin login showed up as expected but still not sign of an attempt on my account. Check Authenticator app sign history and nothing there, no sign of the notification or history of it. It was definitely there.. something I am missing? &#”
