In politics being asked to resign is the same as being fired. And again, his failure to adhere to email standards for using his private email was cited. Why keep dancing around the truth?
i'm not sure you know or understand the facts. It was a standard internal audit report and he resigned after seeing a draft. No surprise given its contents:
"The Ambassador does not read classified front channel messages and has not established a system to have his staff screen incoming cables relevant to Kenya and U.S. interests in the region."
"The Ambassador has lost the respect and confidence of the staff to lead the mission. Of more than 80 chiefs of mission inspected in recent cycles, the Ambassador ranked last for interpersonal relations, next to last on both managerial skill and attention to morale, and third from last in his overall scores from surveys of mission members. The inspectors found no reason to question these assessments; the Ambassador's leadership to date has been divisive and ineffective."
"The respective responsibilities of Embassy Nairobi and the Somalia Unit are clear in principle, but in practice the Ambassador has set a tone that discourages collaboration between the embassy and the Somalia Unit."
"The Ambassador's efforts to develop and focus the mission's work around what he calls "mission essential tasks" have consumed considerable staff time and produced documents of unclear status and almost no value to the Department in approving priorities and assigning resources. His efforts have also created confusion about the relevance of the embassy's annual Mission Resource Request (MRR). The Office of Inspector General (OIG) team agreed with embassy staff that the mission essential task process added no real value to the management of the embassy."
"The Ambassador has damaged the cohesion of Embassy Nairobi's country team by underscoring differences between offices working directly with Kenya and those with regional responsibilities. Country team members, particularly those from other agencies, relied on the recently departed deputy chief of mission to maintain a sense of common purpose at Embassy Nairobi. Unless corrected there is a risk that the country team will become dysfunctional. The Ambassador needs to broaden his understanding of why various agencies are part of his mission, cease avoiding contact with them, and work with the assistance of a senior Department of State (Department) official and the next deputy chief of mission to restore country team harmony."
"The Ambassador's greatest weakness is his reluctance to accept clear-cut U.S. Government decisions. He made clear his disagreement with Washington policy decisions and directives concerning the safe-havening in Nairobi of families of Department employees who volunteered to serve in extreme hardship posts; the creation of a freestanding Somalia Unit; and the nonuse of commercial email for official government business, including Sensitive But Unclassified information. Notwithstanding his talk about the importance of mission staff doing the right thing, the Ambassador by deed or word has encouraged it to do the opposite."
etc.
The report wasn't written to outline the reasons for "firing" him; it was a standard audit report/assessment. He chose to resign after seeing a draft of the report as was widely reported at the time. There were far more issues than his e-mail account, which was mentioned once in a rather extensive list of egregious problems with his occupation of that post. You'd have to be pretty obtuse to portray this as a matter of e-mails. The man was exposed by the Inspector General as an incompetent malcontent who didn't play well with others and wouldn't do his job. Its pretty bad when you can't even handle a cushy post like Kenya and if he hadn't resigned then he should have been fired for those reasons.
