Hi everyone, seeking advice/comments on my situation, I’m about a month and a half at this company (\~200 Employees across multiple cities, on-prem server + FW, Windows/Office365 environment, legacy apps and VMs, etc.)

TL DR:

Junior sysadmin, inherited a complex system from

two seniors (both have left in 3 weeks from my start) - overwhelmed and feeling as an impostor. How (and whether) to address it with the management without loosing my position and bringing panic and uncertainty? How to tell users “I don’t know” or “no” when overwhelmed?

Full version:

Joined the company as a junior admin to substitute one of the two senior admins who was leaving (3 weeks notice from my start) - shortly after I receive the news that the second guy leaves as well = I’m staying alone in charge of the whole system. We’ve had about 3 weeks together for the handover and we have some type of documentation which is mostly notes to some particular recurring topics/tasks.

I’m receiving a lot of requests regarding every subject imaginable from regular users, management, external contractors and service providers.

Feeling overwhelmed trying to solve everything. Saying often to users “I don’t know it yet, but I’ll do my research an come back to you later” and pile up the issues and requests , I solve them in the rate slower than the new inquiries come.

Also Defender / HW Dashboards and such add something to check: (for example, just receinlty we had a critical storage failure at one of the two servers (lucky me) - all other tasks were ofc on hold for the day to figure this out of course - making it stressful to catch up afterwards).

The HW is of older generation 2016-2019 , So the company also wants to “move to the cloud” or to a managed IaaS - of course I’m the main advisor and contact point for that to add to the mix (while

Having very basic experience with exactly this)

Should I address it all with the management / HR? Or shall I “fake it” till the things get better with time? Afraid to loose my position or shatter the confidence of them in me.

Fair to say - the second guy leaving was a surprise to the management as well as they say and they look for the teammate for me this whole time (1.5 months by now) - so I get the support hopefully soon enough in coming months.
