Export file not updating on-disk size
I'm working to break down this 16G PST file into 4.5G chunks for DVD backup. Following the instructions from a previous post [1] I created a new Export file, opened it in Outlook, and drag-and-dropped selections of messages onto this opened Archive. I ended up with one file with 6.6G. Evidently it contains only 2019 and 2023 dated messages. Ok, not ideal, but that's what backups are about. My plan was to duplicate this file, then rename one 2019 and the other 2023. Which I did. Next, I deleted the 2023 dated messages from 2019 file, and all of the 2019 messages from 2023 file. The result was the 2019 file was reduced in size to 0.8G, but the 2023 file has not updated it's size. I expected it to drop to ~ 5.8G, but it's not changed since this morning. I've closed the archive file. I've restarted Outlook. I made sure the 2019 files were deleted from the Deleted Items folder. And the folder in question, Sent Items, only lists the expected 2023 dated messages. Didn't budge a kilobyte. How can I make this archive update it's size?

How to migrate mailbox with over 500 GB - Migration from GWS to M365
Hello, I am trying to migrate GWS mailboxes with over 500 GB to M365 utilizing third-party tool. I have around 50 mailboxes over 200 GB and 10 mailboxes over 500 GB. With third-party tool, I can migrate Gmail to archive mailbox of M365. and I am aware of the fact that it needs auto-expanding feature of archive mailbox. So I have enabled auto-expanding feature for those archive mailbox. However, the thing is the daily growth rate and It cannot exceed 1GB/day as I noticed through below link. https://learn.microsoft.com/en-us/purview/enable-autoexpanding-archiving#more-information The link says like this. Auto-expanding archiving is supported only for mailboxes used by individual users or for shared mailboxes with a growth rate that doesn't exceed 1 GB per day. Is there any way to speed up the growth rate? And provisioning speed also matters. https://learn.microsoft.com/en-us/purview/enable-autoexpanding-archiving#before-you-enable-auto-expanding-archiving the link goes like under. After you turn on auto-expanding archiving, an archive mailbox is converted to an auto-expanding archive when the archive mailbox (including the Recoverable Items folder) reaches 90 GB. It can take up to 30 days for the additional storage space to be provisioned. Is there any way to shorten the days for the additional storage space to be provisioned? How can I overcome this circumstances? or is there an other method to do this? Thank you in advance.How to Enable Exchange Online Mailbox Archives Based on Mailbox Size
This article explains how to use PowerShell to enable Exchange Online archive mailboxes after primary mailboxes reach a certain size. Some simple PowerShell code checks the mailbox size and if it’s too large, enables the archive and assigns a mailbox retention policy containing a default move to archive tag to move items from the primary to the archive mailbox. Some Azure Automation would make sure that the script runs periodically to keep mailboxes in good health. https://office365itpros.com/2023/01/03/archive-mailboxes-based-size/
