Is this for all users or a single individual?<br />
If single individual try setting him up with a clean mail profile under control panel&gt;&gt;mail.<br />
See if that works better.

hi Maclean<br />
<br />
i did that many times also tried other accounts , resulted same error. i think this got to do with virtual directory on IIS, also deleted the folder in user folder local/app /Microsoft/outlook OAB folder <br />
thank you your response
</div>


<div>
Have you attempted to <a href="https://technet.microsoft.com/en-us/library/bb123595(v=exchg.141).aspx" rel="ugc">re-create the OAB virtual directory</a>?<br />
And are there any errors in the event logs to confirm that the problem is IIS related?
</div>


<div>
thank you Maclean <br />
i will try that as soon that box ready, rebooting now, adn will let you know asap <br />
<br />
thanks
</div>


<div>
Ok, I should probably have made a note to make sure you have backups just in case. Should be fine, but never a bad idea to have a backup.

Hi Maclean<br />
<br />
good new More hanging but bad new new error failed 0x80200049, :).<br />
the GAL etc...address is still there i can see all addresses. just not allowing me to download<br />
<br />
thank you, i will let you know if i found something new.

Regarding that error, I think you might be able to resolve that with a CMDlet on the CAS server<br />
<br />
&quot;<b>Update-OfflineAddressBook -Identity &quot;Default Offline Address Book</b>&quot; <br />
<br />
Once done wait for perhaps 15 minutes, then restart the File Distribution Service on your CAS server.<br />
Once completed run the following CMDlet &quot;<b>Update-FileDistributionSer<wbr />vice -Identity CASServername</b>&quot;
</div>


<div>
i ran this and got an error not recognized command &nbsp;&quot;Update-FileDistributionSe<wbr />rvice -Identity CASServername&quot;. so this maybe for ex2010<br />
<br />
the Update-OfflineAddressBook -Identity &quot;Default Offline Address Book&quot; &nbsp;OK it excepted
</div>


<div>
Could be that my notes on the latter command were wrong. It might be &quot;<b>Update-FileDistributionSer<wbr />vice -Identity CASServer</b>&quot; But as I did not make a note whether it has to state the actual word <u><i>CASServer</i></u>, or the <u><i>Server Name</i></u>, I assumed it was the server name.<br />
<br />
(I keep a spreadsheet with handy commands that I don't want to forget :))

<div>
Hi Maclean,<br />
<br />
yest i did my &quot;server name&quot;, BTW the GAL i was able download from inside network but not from outside.<br />
error 0x80200049, same error, but at least now it showed some error not like before just hang<br />
thank you sir
</div>


<div>
Maclean****** you have hit the nail right on the head Brother (BITSADMIN.EXE /RESET)<br />
millions thank you sir
</div>


<div>
Not a problem. I would recommend making a full server &amp;&nbsp;AD backup at some stage, so you can implement CU11 as well. It has various bug fixes that could prevent some other issues, but not critical as your problem appears to have been a mix of 1] Resetting OAB virtual directories, and 2] Clearing BITS queue. So CU11 is merely a recommendation. Enjoy the rest of your week.
