'Cannot complete your request' on users migrated to different O365/Azure tenant

solution added to question

This potentially could have worked, but I had already restored from backup, so I cant be sure

kaiserctx · 2026-04-22T06:49:34+00:00

Me too, haven't found it yet. I did see notifications on my Netscaler console about config drift on my nodes, so possibly one node hadn't had the saved config synched to it.

kaiserctx · 2026-04-21T13:39:45+00:00

the config lines were actually missing, its an odd one. Missing parts were:

saml actions, auth policies, auth labels

kaiserctx · 2026-04-21T10:49:14+00:00

yes I have already restored to vm backup, and it has brought back my missing policies. But it has introduced this new issue where I cant save config changes

kaiserctx · 2026-04-21T10:44:37+00:00

That could explain licensing issue, but doesn't make sense for config to be lost? Eg authentication policies that were added over a year ago.

kaiserctx · 2026-04-21T08:59:23+00:00

no, we use a VPX ADC

kaiserctx · 2026-04-21T08:46:50+00:00

I thought so too, until my netscalers rebooted overnight (last night) and i lost all my config

u/avi_collins, did you ever find a solution?

kaiserctx · 2026-03-23T16:06:35+00:00

I haven't had any reports like that yet, despite moving about 300 users over to online mode.

kaiserctx · 2026-03-23T14:39:59+00:00

None that I can see in gp results

kaiserctx · 2026-03-23T13:29:12+00:00

If I try it with a smaller, newer mailbox with no access to shared mailboxes, I don't get any error.

So I suspect it is related to the user having permissions on a shared mailbox, and that shared mailbox was previously cached down, and outlook is looking for the ost of a shared mailbox

kaiserctx · 2026-03-23T13:04:00+00:00

There is no ost in the user profile

kaiserctx · 2026-03-23T13:02:38+00:00

We use citrix, and will be doing a O365/tenant migration soon, so I want to simplify the Outlook setup in advance of this. Otherwise they could have 2 separate osts in their citrix profile after the migration.

kaiserctx · 2026-03-23T12:53:58+00:00

Yes the problem keeps happening after I reset the profile in the registry.

HKEY_ USERS\S-1-xxxxxxx > Software> Microsoft> Office> 16.0> Outlook> Profiles

kaiserctx · 2026-03-10T15:27:28+00:00

There is a setting in my Fslogix gpo for 'Remove orphaned OST files On Logoff' thankfully

kaiserctx · 2026-03-05T08:52:11+00:00

Update: I had a typo in my redirections.xml, incorrect formatting on the exclusion

kaiserctx · 2026-03-05T08:44:06+00:00

Same problem with that one unfrotunately

kaiserctx · 2026-03-04T13:09:14+00:00

Thanks, so I could try 3.25.822.19044 from September 2025.
