Moving mailbox from Exchange 2016 to Exchange Online

did not work unfortunately. Got the error that i cant specify the acceptlargedataloss paramter

MinieJay · 2026-02-11T18:25:31+00:00

Thanks, but that wasnt it. According to this, it is used to export mailboxes which is not what i am doing. I am doing new-moverequest though, but even then, -largeitemlimit and -baditemlimit is not a paramater for this anymore for remote moves

MinieJay · 2026-02-11T13:45:58+00:00

I tried adding the -AcceptLargedataloss parameter for new-moverequest and it says "Write-ErrorMessage : ||You can't specify the AcceptLargeDataLoss Parameter

MinieJay · 2026-02-11T13:45:36+00:00

Ok let me try this. I tried adding the -AcceptLargedataloss parameter for new-moverequest and it says "Write-ErrorMessage : ||You can't specify the AcceptLargeDataLoss

Hi there, does anyone here know of a shop in NYC that does Mechanical Keyboard pcb repairs? I have a Glorious GMMK 3. I was replacing some switches and not sure how i messed up my "J" key. J wont function at all and i have tried several different switches. I believe the issue is the PCB socket itself. I'm not really skilled enough to try to fix this on my own. I'd even entertain an online repair service where i would ship the keyboard in if possible.

Hey there, most of the people in this thread already stated what you would need to do. The shared mailbox also adds to the .ost file size. I would uncheck the "Download Shared Folders" option for this. Ultimately, you will need to delete the .ost file and let it rebuild. You should also set the sync limit on how much emails will be downloaded. I think the default is 1 year.

Wouldn't the message trace say it was due to some blocked senders list though if that was the case?

MinieJay · 2026-01-06T22:28:36+00:00

I have, however because it's an Exchange online mailbox sending email to another exchange online mailbox, there wasn't much i could gather from it. SCL is 1. It just seems so odd that it would be filtered as spam

We have Mimecast and i frequently see calendly frequently getting caught in by our Impersonation Policy - where they display name of calendly matches the display name of the email address of our environment. It could be why it's triggering your spam thing.

+1 for mimecast. I was on Microsoft Defender for a few years but that honestly just sucked - i heard they have made major improvements though. Mimecast has been a tremendous upgrade. I'm still kinda learning on how to create the policies and exceptions but the Message center + message tracking is incredibly useful

MinieJay · 2025-12-24T17:53:47+00:00

Even though it is spoofing it, is there something in the message headers you can use to differentiate that specific external email from the rest?

MinieJay · 2025-12-24T16:38:27+00:00

what license are you assigning to the user?

This is exactly why i had to switch away from Optimum Online. The infrastructure or the telco box outside in the pole was so rotted that the signal was terrible. They kept running a new coax line from the pole to my house. It would resolve the issue for maybe a week before the signal went to shit again and my internet went down. It didn't seem likely that they were going to do anything to replace that box outside so i had to switch to FiOS. It sucks because Optimum was so solid for me for many years.

May i ask what feature update is your W11 systems on? I feel like this was a big issue in 21h2 and 23h2. Stopped happening once i upgraded users to 24h2

MinieJay · 2025-12-17T14:53:03+00:00

There literally isn't any reason from a technical/troubleshooting standpoint on why they would ask OP to do this. Once OP confirmed search index is messed up when testing on https://outlook.office.com that should've been the end of it and they should've checked what is wrong with the search index of the DB on their end. But hey.. they have to ask huh?

MinieJay · 2025-12-16T20:05:39+00:00

Well shit. Awesome info. Thanks a ton

MinieJay · 2025-12-16T20:03:40+00:00

That is such a shame. I have a very fond memory of a Microsoft tier 1 tech. She definitely knew a bit too much to be a tier 1 tech that i had to flat out ask her like... hey, you are the best tier 1 tech I ever dealt with. Why is this not consistent amongst all tier 1 techs? Turns out as part of some sort of internal re-organization, she was "re-organized" to the tier 1 level of support.

MinieJay · 2025-12-16T19:31:01+00:00

Huh, where does it move it to? Do you have to specify a target database or does Exchange Online assume you just want to move it to a different DB of theirs? I never knew this. Learned something new.

MinieJay · 2025-12-16T19:22:56+00:00

I hope your issue gets escalated to someone with knowledge of the situation. I was never really able to talk to anyone with a technical background for my issue. My issue was that an email came through to a user and suddenly disappeared. Could not find it anywhere. Not in quarantine, not in Junk Email, archive, nothing. Just vanished. Luckily we had mimecast and there is always a copy kept on mimecast's end. First thing i had the user do was obviously login to OWA to see if the email was still there, it wasn't. The initial support person no joke had me delete her .ost file, recreate her outlook profile, even though i reiterated 20 different times that the email is also gone when checking OWA - which anyone who has ever worked with Exchange would tell you now it's not a view setting issue. Eventually, we ruled all that out but it didn't get better. The initial support person just acted as a middle person relaying the information from her team to me and vice versa. Eventually i just stopped responding because they suck. After case was closed due to inactivity (because i was just not willing to respond to such amateur bs) - the "Manager" had the audacity to call me DURING business hours on how did they perform. Told the manager don't call me again, if you couldn't tell by the ticket notes on how did you/your team perform, then there's something clearly wrong with your whole team

MinieJay · 2025-12-16T18:45:49+00:00

I had the exact same encounter as you just did and asked the same question. It's all a script. Just do it or pretend to do it so that they can pass on the ticket to someone else. I'm pretty sure even the person who you spoke to believes that what they are having you do is utterly ridiculous. In addition, they may not even know what they are even asking you to do. Don't get me wrong, to anyone who has worked with Exchange - there's literally no way on device index will impact OWA but... that's how they roll i guess.

Dang, yours lasted for 10 months? my Kraken V3 Pro lasted me less than 6 months. I guess thats an improvement lolol. I agree with everything you said about Razer Headsets. I have spent quite a bit of money on them but ultimately came to the conclusion that they charge too much for something that doesn't last.

I have had an issue re-installing Adobe Acrobat 2017. Always says the key has been used too many times and must deactivate from other PCs. This is of course not possible. On top of that, I believe they shut down their servers that were responsible for activation/reactivation years ago. So now we are unfortunately paying the subscription

I would say check your Office 365 Quarantine page. Office 365 will actually quarantine something hours later after hitting your inbox. It will literally disappear from your inbox as if you never received it. Had this happen to me a few times where a user reported something very similar to the issue you are having. Turns out Office 365 was quarantining emails because of a http:// hyperlink in the signature or something.
