The case ref number is 230-483-398. I was able to talk to a support person in evening and they have recommended upgrading the outlook add in to latest version as we using previous 6.0 add in. But this is still an ongoing issue.
We have ton of errors mostly it starts with 7001, 6259, 6307, 6304, 7180 and 7001 again.
The storage service or any service never stops but users are unable to connect after a while.
The CPU goes to 70 -100%. Most of CPU consumed by storageonlineopns and archive task.
Thanks for looking into it and will really appreciate any help.
Regards
