I used to use writable volumes for OST files, search indexes, ...but stepped away from it completely. Too many problems with writeable volumes in my opinion.
Since a couple of months I am using FSLogix for this (and other) purpose and could not be happier. We did not have a single problem since we moved away from writeable volumes. FSlogix is free (for almost everybody), is easy to setup, faster the AppVolumes, ...
Lieven. Thank you very much for your suggestion and the information.
Although you mentioned that you had too many problems with writable volume,
did you have the same problem (New outlook profile setup is required when user login every time)?
I'd like to accomplish the profile management with the default basic functions first.
Then, if it doesn't work with bug or performance, I'd like to move to another solution(FSLogix, etc.).
However, thank you very much for your kind help.
I did not have the same problems that a new outlook profile setup was required when a user logs in every time. I am redirecting this part of of te profile to redrected folders (outside of App Volumes)
