This has been happening on this computer for weeks now. We have many Gigabytes of data in Outlook folders, but archiving these out to shrink the mailbox size has not improved the performance of Outlook. In fact, many times the archiving process stops completely before finishing.
Aside from that, the rest of the computer is sluggish as well. We are using Egnyte (an online data storage facility) and those operations seem to be sluggish. Internet activity in general is sluggish. We don't have the world's fastest internet connection here, but other computers don't seem to be as bad as this one, even with the same amount of Outlook data in the mailbox, so I'm not convinced that Outlook is the only problem with this computer.
Things seem to slow down even when no activity is taking place according to CPU usage (resmon, etc.). I have disabled things like the indexer and even the Egnyte synch to see if those were slowing us down, but to no avail.
I am here because I need to get this problem solved as soon as possible as it is costing us a great deal to not be able to work on this machine.
I can submit dumps from MiniToolbox, etc. below, but don't wish to post them until they are requested.
Best regards and thanks for your willingness to look at my issue.
