Indexing problems Outlook - Windows 11

What a kind of account are u using? Pop3, imap, exchange? The reason i ask about is, that someone had descripted, that imap/Outlook accounts, who uses ost datafile, instead pst files, get this issue.

Hello,

I have POP 3 email system thank you.

I am using POP 3 as well.

Amanda, Dean,

Have either of you tried the Outlook workaround? The Outlook Workaround is to set a registry key that will cause Outlook to use its built-in search. I created some reg key downloads to make it easier to use, https://1drv.ms/u/s!AobSYdEz_BdhhuZZo1KZ0xAi7U7t-w?e=xZLQna. 

1. To use the Outlook workaround download the enable_preventindexing.reg key from my OneDrive link above.
2. After it downloads click Open and then OK when prompted. This will set the registry key.
3. After the registry key is set restart Outlook Desktop.

You will know the reg key is set because you will see this message above the search results:

After the fix comes out you can disable the workaround by doing the following:

1. In the OneDrive link above download the disable_preventindexing.reg key.
2. After it download click Open and then OK when prompted. This will set the registry key.
3. After the registry key is set restart Outlook Desktop.

Ok, i assume an pst file is used and will clear, that not only an ost file is interlocked, that some user reflects.
