I'm the one who set it up. It's a small team of 20 people. I've done basically no setup beyond the minimum of following docs to get things running. We've had nonstop problems like this since the very start. Files don't upload, anytime I try to fix it I'm confronted with confusing error messages and cryptic things like people telling me "something related to EDR". What the hell is EDR? I just want to view a Word doc.
I've come to realize that Teams should only be used in large companies who can afford dedicated staff to manage it. But it was certainly sold to us as being easy to use and suitable for a small company.
I mentioned that because security software blocking things locally or at the network level is such a common source of friction. I don’t think Teams is perfect by any means but the core functionality has been quite stable in personal use, both of my wife’s schools, and my professional use so I wouldn’t conclude that it’s hopeless and always like that.
Thank you, I appreciate the support. But this doesn't explain the intermittent nature of the issues. For example, just now I tried to open a word file. I got the error message. But then I tried several times and restarted the app twice, and eventually the file did load. It just took five+ minutes of trying over and over.
I also had to add a new user yesterday, so I went to admin.microsoft.com in Edge. 403 error. Tried Chrome and Firefox. Same. Went back to Edge and suddenly it loaded. The like an idiot I refreshed, 403 error again. Another 5 or six refreshes and it finally loaded again and I was able to add the new user. There's never any real error messages that would help me debug anything, it's just endless frustration and slowness.
