We recently started having issues with FSLogix and Outlook and hope someone has seen this before and can offer some assistance.
We have been using FSLogix Office Containers in our VDI environment for a couple of years now without any major issues. However, we recently started having issues with Outlook creating a new OST file every time a user launches Outlook in a new session. This is mainly happening to new users in the VDI environment, and I confirmed this by deleting my profile and logging into VDI as a new user.
If I log into a VDI session and launch Outlook, it will start and say "Preparing Outlook for first use." every time I log in.
Do you have a GPO for the Exchange setting?
User Configuration -> Policies -> Administrative Templates -> Microsoft Outlook 2016 -> Account Settings -> Exchange
And set “Automatically configure profile based on Active Directory Primary SMTP address” to Enabled.
“One time Only”. Using the One time Only will not try to apply the configuration on all subsequent Outlook runs.
Not sur eif the one time will help.
I looked at my %localappdata%\Microsoft\Outlook and see 2 files the same size with different extensions. username.nst and username.ost. You have the same?
Thanks for replying and the suggestion, but for some reason it stopped happening shortly after posting, and the issue has not returned, but I'm not exactly sure why. And I cannot make it reoccur.
FWIW, when the issue was present, I had 6 different ost/nst files in my %localappdata%\Microsoft\Outlook folder. A new one would get created every time I launched Outlook at a new login. All had the same filename with the traditional Windows (1), (2), (3) at the end of the filename.
