While an MDM can limit what apps are allowed (or not allowed) the most simple usage is to tag company owned data.

This way if someone leaves the company with their personal cellphone, the MDM policy can wipe out anything tagged as company property.

@JaredBusch thanks for clarifying the point, that this policy is under the security settings. The app is moot to the policy being there or not if one exists at all.

To clarify further, there were no MDM policies set under Device Admin outside of what O365 already applies. I did remove that but that caused it to log out of the account/remove it and when I reconnected things, the problem went away as I anticipated. Still was curious as to why it was happening though. My best guess is what I previously mentioned about him connecting to an open hotspot and it causing the issue.

Obviously those instructions are just ripped from Google, but the same process should apply.

He doesn't have any MDM applications installed, therefore none to remove

Did you check the settings to confirm?

Yes I did. Although it was difficult to sift through his list of apps to see if any were installed. Which just reinforces the need to seriously look into a good MDM solution which whitelists certain approved apps which can be installed.

FFS.... He is not telling you to look for an app. You are looking for specific MDM policies in the settings.

Simply making a comment in reference to last portion about "Uninstall the ME MDM App" and how not only was it not installed, but he also had a large portion of other unnecessary apps on his phone. I did also check the Security settings he referenced.

With O365 are you not using an MDM to authorize the device?

Not at this time, no.

An Cert that is good for 24 years. . . yeah sure, I'll just trust that.

That is normal for a self signed cert for a local device. The last thing you want is for the self signed cert on a piece of gear to expire.

While I get that, but Samsung shouldn't have an Fortinet cert, at least you wouldn't think they would.

It doens't something on his device tried to connect to something and Fortigate got in the middle.

My money is on this happened outside the office and the user ignored it until they could come in to IT.

That's what I was wondering. He started noticing it around lunch so I was thinking he could have potentially ran out and connected to some open hotspot, at which point his mail tried to sync and he received that certificate error. My confusion is I would think once he disconnected and connected back to mobile data or our network that it would no longer give that message. Is it possible that the message will continue to stay up until acknowledged in some fashion? Restarting the phone did no good.

The obvious next step is remove/re-add the account, but I'm currently more interested in what would be causing this at this point. He's currently the only user seeing it, so has to be something related to him and his phone.

User just came into my office showing the following. When trying to sync his work email (Office 365) he's getting a message that there's an invalid certificate and would he like to Cancel - View - Continue. When we view it, we see the following image.

• This is on a Samsung Galaxy S9 fully updated.
• We do not use Fortinet anywhere in our network.
• This occurs over Wifi connection or mobile data.
• He currently isn't using any VPN app or otherwise which would re-direct traffic.

Honestly not sure what to make of this.

@JaredBusch I feel that pain. Wells Fargo is my mortgage holder/servicer.

I had them for 5 years - never had a problem, not once.

Of course - i was never late with my payments either.

The only problems I've had with them is that their account people have no idea how to calculate what to take out for escrow. Every year they send me a check because they take too much. I've tried calling and going over the numbers with them, and they just don't get it. I'm half tempted to just say screw the escrow altogether if they'll let me. Referring to the stupid letter at the end of the year saying "you have these choices for your escrow payment... if you do nothing your payment will automatically raise to this amount"

Now that I type this it totally seems like a scam, given Wells Fargo's reputation. Take way more escrow from every single customer and profit on the interest. Bastards.

I cancelled my ESCROW account as of last year for a couple reasons. I'm one who shops around home/auto insurance annually and every time I switch home insurance it's a nightmare. As you say, the amount they deduct is always off, and usually on the high side (although this makes sense on their end to ensure that always have sufficient funds). Plus it puts me in control to hold my money and earn interest on it and pay my property taxes in the most tax efficient way for me.

For this volume we get the Brother HL-L6200DWT. We have primarily Brother printers and have been very satisfied. Printer and ink costs seem to be among the lowest we've found.

Agree that the HL-6200 model is solid

The best were the HL-5370DW. We just had two that FINALLY gave out around 150,000 pages. We still have about 5 or 6 around and they simply work. Never have issues just replace toner and the occasional drum.

The HL-5400 series had issues with their fusers, mainly if you were a decently high volume printer (1000+ pages per month). Less than 500/month we haven't had the same issues.

We have two HL-L6200 currently. The first one we bought kept creating creases down the middle of the page. Apparently it's an issue others have experienced as well and Brother exchanged it. The new one hasn't had that issue yet and it's been in place over a year now.

The only complaint I have is how the toner acts when it gets low. Many times when the printer says it's time to replace toner, the quality is still fine so you can reset the counter and keep printing. Unfortunately if you do that, eventually you'll start seeing toner slowly seap out onto the pages and if users aren't aware of what it is and let it continue, it can create a mess. We just train our users to change toner out at the first sign of this.
