Outlook version
Outlook 365 64 bit
Email Account
Office 365 Exchange
Operating system::    Windows 10
Outlook version:     2503
Email type or host:    IMAP
I have an MS365 subscription (personal). I use Outlook version 2503 for MS 365. I use quite a bit of VBA, including to do searches across multiple mailboxes.

Recently, when starting Outlook, I've been asked if I want to move to the "new" version, and I answer NO.

This time, I got an error that I had to, apparently. Then I got an error that it couldn't install, then a second occurrence of Outlook opened, this one version 1.2025.416.400.

While that 2nd occurrence was opening, I was in my chosen version trying to run my search that shows all Inbox messages across all accounts received in the last 24 hours. I got this error from VB: "Run-time error '-2146959355 (800800005) server execution failed." It occurred on this line of code: "myolApp.ActiveExplorer.Search txtSearch, olSearchScopeAllFolders" but I was able to hit Run and proceed, and the script completed.

What is going on? What does this error mean, and do I have to use the new version? It doesn't seem to support VBA and, if that's the case, Outlook will no longer meet my needs.
 
As Diane has pointed out numerous times, you do NOT have to switch to the New Outlook.

Classic Outlook is NOT Going Away in 2026
Toggle out of the new Outlook for Windows - Microsoft Support

But you may have to pay to get Classic Outlook, or stay on it.

As far as I can tell, you must have a Microsoft 365 Subscription Plan that includes "Desktop versions of Word, Excel, PowerPoint, and Outlook" to stay on Classic Outlook. e.g. "Microsoft 365 Business Standard" but NOT "Microsoft 365 Business Basic". You will certainly want to verify what your plan includes before making any changes.

If you do not want to subscribe to a paid Microsoft 365 plan to get Classic Outlook, then you might want to consider buying a license for Office Home & Business 2024. This includes Outlook 2024. The latest version of the full featured, Classic, desktop, stand alone, perpetual license Outlook.

I'm sure Diane has additional insights on this subject. You might want to start a new post specifically for "How to stay on Classic Outlook?"
 
or, perhaps find a copy of office 2010, or 2016, which will likely be pretty cheap or free from someone that isn't using it anymore. Seems these are what Hornblower409 and Diane are using.
 
If you use outlook.com or Microsoft 365 business you need a current version of office - 2024 is pretty cheap from stacksocial. The older versions of office can't connect to Exchange online. (If you need publisher too, get 2021.)

But, the subscription will have classic until at least 2029. If it is missing, from a new install it can be installed from the store or downloaded.
