@MAS,<br />
&nbsp;<br />
&nbsp;Can I try all these:<br />
1. restart service &quot;Microsoft Exchange Search Indexer&quot;<br />
2. Update-MailboxDatabaseCopy<wbr /> &quot;database1&quot; -CatalogOnly<br />
3. Rebuild the index<br />
<br />
While mailbox database is mounted and users are using emails?
</div>


<div>
Try one by one 1, 2, 3<br />
I suggest you restart service &quot;Microsoft Exchange Search Indexer&quot; and check.

Do I need to reboot the entire server?

--&gt;Do I need to reboot the entire server?<br />
Please be patient.

<div>
&quot;Please be patient.&quot; ---&gt; No problem. I can wait. By the way, does this impact Exchange server operation all all? Would Outlook users feel any impact while this service is being stuck?
</div>


<div>
1. restart service &quot;Microsoft Exchange Search&quot;<br />
2- &nbsp;restart service &quot;Microsoft Exchange Search host controller&quot;<br />
3. Update-MailboxDatabaseCopy<wbr /> &quot;database1&quot; -CatalogOnly<br />
4. Rebuild the index<br />
5 Wait for a little while until it gets healthy.

<div>
I had Microsoft Engineer kill the processor and start the service.<br />
Now the condition is Healthy.

(1) &quot;restart service &quot;Microsoft Exchange Search&quot; --&gt; I think this did the job.<br />
(2) restart service &quot;Microsoft Exchange Search host controller&quot; --&gt; I do not see &quot;Microsoft Exchange Search host controller&quot; in my Services.msc. However I see &quot;Microsoft Exchange Search Host&quot;. Is that the same thing?<br />
(3) &quot;Update-MailboxDatabaseCop<wbr />y &quot;database1&quot; -CatalogOnly&quot; --&gt; When I run this command, I get the following error:<br />
[PS] C:\Users\admin\Desktop&gt;Upd<wbr />ate-Mailbo<wbr />xDatabaseC<wbr />opy &quot;new_mailbox2&quot; -CatalogOnly<br />
Database &quot;new_mailbox2\*&quot; has only one copy. This task is supported only for databases that have more than one copy.<br />
Fyi, this is the only exchange server in the organization.
