There is a size limitation for Inbox, Outbox and the like. Whenever you delete an email (say a junk mail), Outlook will put a &quot;flag&quot; in the email message and make it disappear in the Inbox folder.<br />
<br />
However, the deleted message is still there, occupying hard disk space and making the Inbox fatter. To physically remove the deleted message, you have to pack or compress the folder (Inbox/Outbox) in question. Inside Outlook, use the HELP function in Outlook to find out how to perform this action.<br />
<br />
This also applies to Outlook Express. The size limit is 2GB beyond that the folder will corrupt.

pradsmk--Thanks, but that article is referring to migrating mailboxes. &nbsp;This mailbox was not migrated and was created on Exchange 2007, where it still resides.<br />
<br />
Jimmy_Ho--That's really not relevant to my issue at all. &nbsp;This is an Exchange mailbox that does not have a limit. &nbsp;Further, it's only 84MB anyway.

Try to re-configure one user outlook profile, if it is not working check the Auto discover setting.
</div>


<div>
Auto discover is working fine as we do not have any issues with other users. &nbsp;In addition, autodiscover works fine on new PC setup for everyone else. &nbsp;It is only this one user account in question now that I have recreated the first one.

Hello,<br />
<br />
Please restart the information store service and RPC Client Access service, and then restart the Outlook and see it.
</div>


<div>
As I said above, I already restarted the entire server. &nbsp;This did not resolve the issue.
</div>


<div>
Please try the below given steps :<br />
<br />
It seems the problem is in the Legecy DN, &nbsp; <br />
<br />
Legecy dn = /o=ORG/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recip<wbr />ients/CN=p<wbr />art1lastna<wbr />me\-part2l<wbr />astname, firstname mi<br />
<br />
The \ after cn= maybe causing the problem. &nbsp;Once you remove the / so that the name read &quot;CN=part1lastname-part2las<wbr />tname, firstname mi&quot; account could be opened using Outlook.<br />
<br />
Please let me know if this solution works for you.

<div>
Glad to hear that, Thanks for sharing the solution.

I had a user yesterday who could not open her mailbox with Outlook. &nbsp;I checked the mailbox on a terminal server and had the same issue. &nbsp;The strange thing is that I could access the mailbox via Outlook Web Access without any problem, and I also could open her inbox (File--&gt;Open Other User's Folder) with a domain admin account in an Outlook client without issue. &nbsp;I gave up diagnosing the issue and just deleted and recreated her mailbox and this resolved the problem.<br />
<br />
Later in the afternoon, I had another report of the same issue with another user. &nbsp;At this point I do not want to just delete and recreate his account, I want to resolve the issue.<br />
<br />
I've tried rebooting Exchange.<br />
I've tried disabling and then reconnecting his mailbox.<br />
There aren't any events in the event viewer on Exchange.<br />
I have over 100 other users who are not having any issues.<br />
<br />
I'm lost at what to do next.
