Microsoft Teams status is stuck on "Out of Office"

Someone has sent an invite with "out of office" selected. You must click on invite and choose "free".

I deleted the Application Cache, as well as deleting and declining a week-long out of office calendar event from a colleague I'd previously accepted (had to dig it out of the trash to decline it). I also deliberately set myself as out of office for 15 minutes. None of those things cleared the status right away, but about 20 minutes after the deliberate out-of-office event, the status cleared up.. no idea which of those things caused the "out of office" status in MS Teams to go away, but one of them did, so I'm listing them all here :) Note that I did NOT get around to deleting the blob_storage, so don't think deleting that one is necessary.

Note I'm on a Mac, so instead of deleting the items in %appdata%\Microsoft\teams\application cache\cache, I deleted them from ~/Library/Application Support/Microsoft/Teams/Application Cache/Cache/:

kgreenwell@srq3288:~$ cd /Users/kgreenwell/Library/Application\ Support/Microsoft/Teams/Application\ Cache/Cache

kgreenwell@srq3288:~/Library/Application Support/Microsoft/Teams/Application Cache/Cache$ ls -l

I had this same issue - posting this resolution that worked for me, in case it helps others.

I performed all the suggestions in this thread up to the cache clearing...nothing worked.

I opened an Incognito window in Chrome and signed into O365 there. Opened the web version of Teams. Changed my status using the drop-down. Finally, it saved, got rid of my OOO status and showed the correct status in the web version. Went back to the desktop app and it was fixed there as well as a result.

Who knows why this worked - this is definitely a bug.

Sadly, the Microsoft Teams Uservoice threads eventually direct everyone back to this forum entry.

The Unified Presence Service will update Teams OOF based on Automatic Replies OOF or Calendar appointments set to show status as OOF. In this situation, you can filter client query to search for OOF, then remove these calendar items. 

I understand the rationale behind this. But it becomes annoying quite fast. I'm working from different offices throughout the week without a pattern from week to week. In order for my colleges to know where I am I add "Working from elsewhere" full-time in my calendar and the name of the office in the subject field. I believe I'm not the only one in the world doing this :)

If I understand this correctly, Teams will read this as OOO and even refuse me to override the status to e.g. "Available" (I tried with the commands mentioned above - command was accepted, but no change still). The interesting things is that SfB show my status correctly. Teams icon on the taskbark show the "available checker icon", but in Teams itself I'm OOO. 

In order for Teams to show the correct status I would have to stop using "working from elsewhere" calendar entries, which I would say is a bit stupid. There is a reason why I'm using it. Why cannot Teams use similar mechanism as SfB? If I'm on my computer I'm available unless actively in a meeting or away. If we copy this Teams-mechanism to SfB I guess I would "appear as offline" or be "offline" all day long which would not make sense.
