Outlook 2010, iCloud, and Eset Outlook addon causes Outlook to hang

There's apparently some incompatibility between the iCloud Outlook addon and the ESS5 Eset Outlook addon in Outlook 2010. When both addons are enabled, and I try to access anything in iCloud, then Outlook starts to hang for quite a while (at least 15 min before I became impatient and killed it). Access to the iCloud part works fine if I disable the Eset Outlook addon, and I can see no obvious issue if I disable the iCloud addons but have Eset Outlook addon loaded.

What does the Eset Outlook addon do? And is there a way for me to have it loaded and have both operating fine?

Issue Reproduction:
1) Load Outlook (with both ESET Outlook Addon and iCloud Outlook Addon)
2) Try to access any iCloud items, such as contacts and email

Hello,

I have asked ESET's QA department to investigate this.
