<div class="content wysiwyg-content">
I have the following message in my Exchange Server computer's Application Log right after restarting the Exchange Server services:<br />
&quot;The Exchange IFS failed to map drive ?:. Please free drive ?: to use Exchange IFS.&quot;<br />
<br />
I followed the link to Microsoft Article 273151 which says:<br />
CAUSE<br />
This behavior occurs because the Exchange IFS drive does not dynamically map. It gets mapped statically according to a registry value. <br />
<br />
RESOLUTION<br />
To resolve this behavior, change the mapping of the conflicting network drive.<br />
<br />
Question: how can I find what drive letter the Exchange IFS drive is using via the Registry to I can map around it? Why do I have a question mark instead of a drive letter in the event log message?<br />
