I migrated to CU19 as one of the attempts to resolve). One difference is that we are running our own Exchange 2013 CU19 (though we were running CU16 when the problem first began. License, only on those with click-to-run install. The issue does not occur on clients with full open About 50 clients using the same Office 2016 click-to-run install. In Mid-December the issue began occurring. I have encountered the exact same set of circumstances over the last month. CU8 is too new so I am hesitate to upgrade to it at the moment.Ĭould anyone give me a hint how to check and find out what is going on? Are there some settings changed on server after upgrade? Never seen Loading Profiles message before CU7 upgrade. I now also notice the message 'Microsoft Outlook is synchronizing folders' appear and stay quite often. There is no difference in term of Avg Resp, Avg Proc when Outlook loading fast & slow Outlook.exe /safe fixes just for a day or after a few closing/opening, Loading profile comes back again. After it is connected, everything is normal.
After upgrading in house Exchange 2016 from CU5 to CU7, I noticed all Outlook 2016 CTR stuck at Loading Profile for more than 60 secs.
