Outlook 2016 - New Mailbox Size Limit Imposed?

[shopper150]

I have a user who has a 60gb+ mailbox size.
It's hosted on Exchange 2010 and has been running fine for many years.
I've recently set up a new machine for him, and on downloading/synchronizing the mailbox locally, I'm getting an error advising that the mailbox is full. The user has two other machines where this is not an issue.

Now I'm convinced that this is a local issue due to an Outlook update (I downloaded Office 365 from our E3 portal) and not an issue with the hosted mailbox actually being full (as other machines with same user's mailbox running slightly earlier versions of Outlook 2016 are running fine.

Does anyone know how to work around this?

Is all that is in the inbox?

If so then you can setup some archive files i.e. .pst files which can be on the local machine but available in outlook.

Have you ran ScanPST and compacted?

I have compacted via Outlook, but haven’t run ScanPST. I don’t think it’s a corrupt PST, I’m convinced it’s the Outlook application not permitting a full download of all mail.

I’m keen to have everything in the hosted mailbox, and I’d also like to understand why it’s working on the other machines and not this new one.

But if I can’t get it to work, this would be the only other option.

There's a registry setting for maximum PST file size, let me dig out the instructions to increase it, I used to have to do it all the time in a previous life.

That looks like it will do the trick!
Will give it a go.
Many thanks

It is the size of the mailbox on the server. I’d recommend exporting the Deleted Items folder on one of the machines that is working and then emptying the deleted items before compacting. Or you could increase the size of the mailbox.

Do you / they have a plan to get them off Exchange 2010 before it goes EOL in January?

For sure, going to move to O365
Although I’m not sure they support mailboxes over 50gb

Any idea why it works on the machines that have already been set up if it’s the server causing the issue?

the server limit is a hard limit, It's main use is for admin/Storage/Billing.

The local is a soft limit as OSTs over 50 GB perform terribly but as you suggested earlier it's probably corrupt and if all you user does is check his current mails and reply if necessary they might not notice that inbox search no longer works.

Turn off cached mode on the account and you'll see if it's a server or client issue.

I bet you half of that data is stuff already saved on servers shared around as attachments rather than links.
It's a right pain having to manage bad practice by users. I bet they will cry if it all went tits up.

This.

Not been at the pointy end with this sort of thing for a while, but avoiding telling them to sort their stuff out will end in tears for you (OP) as well as them. Been there, got the t-shirt.

There's simply zero reason for having mail stores that size and so many downsides it's untrue. Education required, not circumventing a problem waiting to happen

Can go up to 99gb.
