I had a funny little issue with my PC at work that took me a fair while to figure out today. I’d set up a new Site Collection in Sharepoint and connected it to Outlook (something that I’d never done before) and it was excellent…I could see all the different documents (Excel sheets, Word docs etc) in Outlook just as I could in the portal…nice
However after a while I noticed that Outlook was taking it’s time to send mails etc and then when I tried to swap to another application-it all went wrong! Apps started “not responding”, hanging, the works…a quick CTRL+SHIFT+ESC and Task Manager showed OUTLOOK.EXE on 99%…WTF!!! I killed the process tree and restarted Outlook but to no avail…I rebooted my machine too but it was useless; my processor was maxed out.
I started turning off add-ins in the Trust Center and then noticed 3 search/index related processes in Task Manager so I killed those and disabled indexing of the Sharepoint list I’d created. This was bound to work so I closed and re-opened Outlook and it was on 37%…not brilliant but better, then all of a sudden BOOM-99% again…holy maxed out processor Batman!
After having a look online I became pretty sure that it was related to .PST files but I was equally sure that I didn’t have a .PST file so that left me in something of a conundrum! However I went off to have a look anyway in:
C:\Documents and Settings\<Username>\Local Settings\Application Data\Microsoft\Outlook\<PST File name>
and what I found was interesting. While there was no Outlook .PST there WAS a Sharepoint List .PST…I deleted that and lo and behold, Outlook started behaving again (I also deleted the list from Outlook).
While I was happy to sort the problem out and be able to use my PC properly again, I am sad that I seemingly can’t have Sharepoint lists in Outlook Perhaps if I’d left it for a while the indexing would have finished and calmed the processor down but I just don’t have time for that…if anyone’s got any ideas please let me know!
